cannot install on os x
hi, i tried two methods as described on the home page:
conda install gr works but installs the old version 0.18. i then uninstalled that again.
conda --version gives 4.3.25.
pip install gr. my pip is the one from anaconda since the paths are set up that way. however, this installation fails during build. here is a snippet of the output:

and the output ends with

how can i install a recent version of gr on a current os x system?
Qt widget with matplotlib API
gr can currently be used as a matplotlib backend and as a Qt widget, but could it be possible to use both simultaneously? Namely, have a Qt widget (say, of MatplotlibGRWidget class), which would have a .figure attribute, that would be a matplotlib.figure.Figure.
allow selecting line type for grid
Currently, the grid is always drawn with a solid line type. It would be nice to be able to select the line type as for other lines.
Latest GR conda package for Linux is missing
I just checked in https://anaconda.org/jheinen/gr/files and saw that the latest conda package for GR is 0.15.1. It's not a big deal since the recipe is in the repository and I can build it myself, but leaving the note here still.
(By the way, I didn't see a changelog and the versions are not tagged in git - so while I feel like using the latest version, I don't really know what the improvements are)
grid lines
i would like to draw a rectangular grid of lines in the xy-plane with gr3. so far i could not make it work. i tried something like this:
self.mesh = gr3.createsurfacemesh(
self.segments[0], self.segments[1],
xs, ys, zs,
option=0 * gr3.GR3_SurfaceOption.GR3_SURFACE_FLAT)
and then
gr3.drawsurface(self.mesh)
but this made the entire viewport white.
follow-up: how to draw a cuboid - line grid in 3d?
can not run qt examples
Dear,
I have installed gr on linux and mac os using conda install and am getting the following error when trying to run the qt examples (mri.py or qtgrdemo.py):
GKS: dlopen(/users/joao/local/conda/envs/sorting/lib/python2.7/site-packages/gr/lib/qtplugin.so, 1): image not found
Is it not configured for using qt when installing from conda?
Is there an example for compiling from source it with qt?
Thanks in advance, Joao
ambient lighting
is it possible to create a more diffuse lighting style? in the api it seems there is only a specular light with a prescribed direction?
Import fails, installing using `conda install`
I installed gr using conda install -c https://conda.binstar.org/jheinen gr.
I use Anaconda Python installed in the locaiton /Users/allan/homeInstalled/anaconda/, but since I use virtualenv, I guess gr is installed somewhere in /Users/allan/homeInstalled/anaconda/envs/py27/
I get the following error when I import gr in python:

DOC: gr.herrorbars, gr.verrorbars wrong documentation for e1, e2
The parameters e1, e2 do not define the absolute deviation at a given point (px, py).
- We assume we have a given point (px, py).
- and the absolute deviation at a give point in negative and positive direction (dneg, dpos).
Then e1, e2 defines the following:
gr.verrorbars:
e1 = py - dneg
e2 = py + dpos
gr.herrorbars:
e1 = px - dneg
e2 = px + dpos
We should fix the documentation for both.
pip3 install gr results in error
When building under python3.3 - libraries can't be found in final link. The reason is - in my environment cython built files have SOABI extension like this - ./build/lib.linux-i686-3.3/gr/libGKS.cpython-33m.so
Here is the patch to fix this issue:

please check against mpl master
We are in the process of wrapping up matplotlib v1.5.
One of the major new features is, when in interactive mode, changing the state of Artist objects will trigger a re-draw of the figure. This relies heavily on the backends to have implemented draw_idle (which from quickly skimming https://github.com/jheinen/gr/blob/master/lib/gr/python/gr/matplotlib/backend_gr.py it looks like you do not implement and I don't know enough about the details of gr to your implementation of draw is lazy or not) to correctly defer actually re-drawing until the screen is ready for an update.
I only became aware of gr about 15 minutes ago, but it looks very interesting. If you would like, could you add a blurb to the mpl docs that this exists (maybe in http://matplotlib.org/devdocs/mpl_toolkits/index.html grouped in a new heading with the iTerm backend?) ?
I would definitely be interested in working together on the mpl backend, please be in touch!
colors format in mesh functions
this is about the python wrapper - should i file in sciapp/ somewhere instead?
gr as backend for matplotlib: Can I save images as png?
Hi,
I am new to GR. I read on the GR homepage: "... GR can be used as a backend for Matplotlib and significantly improve the performance of existing Matplotlib or PyPlot applications...".
Can I use the GR backend to write a png (without using pyplot)?
How?
Will this be faster than using the agg backend?
I experimented with the sine example form the homepage. If I use it with plt.show(), using the gr backend is about 1.5 times faster than using the tkagg backend.
If I naivly replace plt.show() by plt.savefig("test.png") the gr backend is slower than the agg backend.
If I have a closer look at what functions are called, I realize that no matter what backend I specify always the file backend_agg.py is used, if I want to save a png.
Thanks
Martina
cellarray gets slow/crashes when zooming in
When zooming into images drawn with cellarray, it appears that the whole zoomed-in image is drawn even if only a small part of it is visible within the bounds of the window.
For example, this display of a 64x64 cellarray crashes (X11 terminal):
import gr
import numpy as np
gr.setviewport(.1, .9, .1, .9)
gr.setwindow(0, 2, 0, 2)
N = 64
a = np.arange(N*N)
gr.cellarray(0, N, 0, N, N, N, a)
In Qt, there is no crash but the drawing becomes slower and slower, and at one point Qt warning messages of the form "QImage::setPixel: coordinate (67671,5) out of range" are emitted for each pixel.
how do I get a working C development environment
Using Ubuntu.
Installed python-gr to obtain code - no clear way to get C stuff without python or julia.
Built griddata example: cc griddata.c -I/usr/local/gr/include -L/usr/local/gr/lib -lGR -lm -o griddata
Added: export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/gr/lib
Did a symbolic link to fix missing fonts error: sudo ln -s /usr/local/gr /opt/gr
Finally get the message: GKS: X11 support not compiled in
How can I get the C use of GR working - is there a doc somewhere?
no win64 binaries
See title.
PNG output in C/C++
I am unable to get PNG output when using gr in C++. PDF output works fine, but something seems to be silently failing when using a png file extension. The same code translated to python works just fine, and outputs to PNG correctly. I have checked, and both the C++ code and python are using the same installation of gr, built from source. For reference I am using beginprint and endprint, and the C++ executable successfully outputs a PDF when the pathname is set to have a .PDF extension. I have had little luck trying to figure out the cause as the program still completes, and the GKS window does flash, but no png file is written at the end. The program then exits with error code 0
axes labels?
i see titles3d, but how does one create labels for 2D plots? for example,
julia> using GR
julia> GR.plot(1:10.,1:10.)
then what? thanks.
corrupted double-linked list

After running it two or three times. This is what I get for pendulum3.py (http://gr-framework.org/examples/pendulum3.html)

How to use drawimage to render a 2D array?
Hi,
New user to GR. One small question: I tried to use drawimage to render a 2D float-type array using whichever colormap, but did not figure out how to do that. Can anyone indicate?
Also, could anyone indicate where I can find the source code for the image plot (the first image on the homepage, http://gr-framework.org/, the 2D image plot with a logarithmic colorbar)?
Thanks very much!

Differences in rendering with matplotlib's agg backend
Running examples/matplotlib/artist_reference.py with matplotlib's (qt5)agg backend (left) and with the gr backend (right) reveals a few differences:
- gr does not seem to use antialiasing (this is clearer if you click on the screenshot to open it with its original size). Is that correct?
- color rendering seems different.
gr 0.23.0 and matplotlib 2.0 installed with pip on Python 3.6, Arch Linux.

Building on windows with Qt5 fails
Setup.py does not link against Qt5Widgets.dll
How do I build with 3rd party packages on OSX?
I would like to add Ghostscript and a few other packages to my GR source build. I do have the Ghostscript libraries and headers on my system (from homebrew), but it was not linked into the standard search paths like /usr/local/include due to conflicts. I see that Ghostscript is not reported as part of the build when I type make. What is the right way to specify 3rd party package locations in the GR build system?
wrongly formatted floats in PDF output when locale set in program
When a program uses setlocale() - as done in Qt by default - and the locale has a LC_NUMERIC setting that formats floats differently (e.g. "," as decimal point) the values written to PDF files during beginprint/endprint are wrongly formatted and cannot be read by PDF viewers.
This can be reproduced with e.g.
LC_NUMERIC=de_DE.UTF8 python examples/qtgrdemo.py
and then saving the plot as a PDF.
A workaround might be to use uselocale() to reset the locale to C in the thread that writes the PDF.
Long-running 2D graph leads to access violation
Hello,
I have the Python Qt-based GUI which is using the GR to draw eight curves. I am using the Plot once, the PlotAxes once and the PlotCurves 8-times.
I do the refresh every 40 ms. Before every refresh the curve values are shifted by one and the new value is added to the end. The X value grows by 0.04 for every refresh and thy Y values are within -1 to 1 range. All the curves are shifted in the same way, so the X axis is always in the range of approx 10 seconds, so there are 250 values within a short numeric range.
Everything goes fine for maybe 12 to 15 hours, but after that I receive this error:
origin outside current window
origin outside current window
Traceback (most recent call last):
File "C:\Anaconda\lib\site-packages\qtgr__init__.py", line 294, in paintEvent

File "C:\Anaconda\lib\site-packages\gr__init__.py", line 249, in updatews
__gr.gr_updatews()
WindowsError: exception: access violation reading 0x00000000
Unfortunately, I'm unable to compile the binaries on my Win7, so cannot debug the exact place where the binary fails.
I have no idea what I am doing wrong, but in general I hope the curve values are ok.
Thank you

scattered data interpolation
Hello GR and Josef Heinen,
I am looking for a way to do scattered data interpolation in Julia. Perhaps GR.jl might be helpful. I read your example
xd = -2 + 4 * rand(100)
yd = -2 + 4 * rand(100)
zd = [Float64(xd[i] * exp(-xd[i]^2 - yd[i]^2)) for i = 1:100]
using GR
x, y, z = GR.gridit(xd, yd, zd, 200, 200)
But is it also possible to return the (interpolated) value of z for a specific inputs (x,y)? So I am looking for a function like the following one:
zi = GR.somefunction(xd,yd,zd,xi,yi), where xi and yi are some specific values for x and y.

compiling under windows 32/64 with mingw64-static ?
Hi,
I would like to install (compile) gr with the mingw64 static compiler from Carl Kleffner (carlkl)
(https://bitbucket.org/carlkl/mingw-w64-for-python/downloads)
Do you think it is possible ? (I'm not expert at all in compiling outside of %cython, so I have no clue)
Installation MacOS Anaconda 3.5
Hello!
I have some trouble installing gr on a MacOS with Python3.5 on Anaconda.
I get the following error message, no matter what way i try to install:
...
File "setup.py", line 1493, in finalize_options
check_ext.finalize_options(self)
File "setup.py", line 846, in finalize_options
build_static.finalize_options(self)
File "setup.py", line 117, in finalize_options
if version[0] == 10 and version[1] < 7:
TypeError: 'map' object is not subscriptable
What can i do?
Another question i have:
I would like to visualize 3D-Data (some hundred datapoints/ dataset), which should rebuild as quick as possible. Is gr the right tool for this? Or would PyQtgraph or Vispy or something else be more suitable for this case?
Thanks a lot!

Keeping windows open when using gr as matplotlib backend
gr seems to return immediately after plt.show() when used as a matplotlib backend (e.g. MPLBACKEND='module://gr.matplotlib.backend_gr' python examples/matplotlib/artist_reference.py momentarily displays a window, then immediately closes it and the process exits). Would it be possible to instead make show() blocking and keep the window opened?

Look of markers
Really love GR, and mostly I use it for heatmap and line plots. However, every now and then
I use scatter plots and noticed the markers look a little "low quality", e.g. circles have little nicks and
such, namely at the top and left hand side of the marker.
I then switch to pyplot or plotlyjs for scatter plots, but I d like to stay on GR as much as possible :)
Did Pkg.checkout() to get latest version and I am on Julia v0.5 Linux.
Thanks for all the effort you put into this!

setcolormap documentation
Hello,
I am using GR with Julia and ran into some confusion with the colormaps and cellarray. In the code below, I display a cellarray with linearly increasing Int32 values: 1 , 2, 3, 4, ... n. On each each iteration of the for loop I change the colormap, but only a subset of the cells actually change color
import GR
function draw_pics(image, n, cmap)
GR.clearws()
GR.setwindow(0, 100, 0, 100)
GR.setviewport(0, 1, 0, 1)
GR.setcolormap(cmap)
GR.cellarray(10, 90, 10, 90, n, n, image)
GR.updatews()
end
for i in 1:100
n = 40
x = ones(Int32, n^2)
cumsum!(x, x)
reshape(x, (n, n))
draw_pics(x, n, i)
sleep(0.1)
endWhat is the logic for converting the values to the colors by the colormap here?
Compile with mingw as c++ library
Hi! I'm looking for some documentation about compiling on windows? Is it possible? Is also possible to compile it only as c++ library?
One of equation in spline.c is incorrect
In gr/lib/gr/spline.c line 355,
The correct equation is
R(i, 0) = 1 / (*p * C(i - 1, 0) + *q * T(i, 0) - f * R(i - 1, 1) - g *
R(i - 2, 2));
instead of
R(i, 0) = 1 / (*p * C(i - 1, 0) + *q * T(i, 0) - f * R(i - 1, 1) + g *
R(i - 2, 2));
It is "-" instead of "+".
some line types are not as expected in Qt
Some of the line types look not as expected in the Qt backend. For example, LINETYPE_SPACED_DOT looks like solid lines with inconsistent 1-pixel breaks.
LINETYPE_DOTTED does not have equal spaced dots, but looks like this:
In general, dots usually appear to be 2-pixel length lines.
no conda packages for py3.5 macOS
I was trying to test out gr on anaconda but I ran into a unsatisfiable error with the conda install on macOS. It appears that there are no python3.5 conda packages uploaded to https://conda.anaconda.org/jheinen so that explains why I get the error. Is there any chance python3.5 artifacts could be made available?
Create a mailing list of forum to support gr users
Hello,
I have an installation problem with gr, but I do not know, where I can ask questions.
Is there a mailing list for gr users?

gr crashes on executing the example
I installed gr using conda install -c https://conda.binstar.org/jheinen gr on mac osx 10.8.5. There seems to be an issue with the 'libfreetype.6.dylib'.
When running the example from the gr website:
from gr import pygr
pygr.plot([0,1,4],[3,2,5])
gr crashes and leaves an item named: "libfreetype.6.dylib" in the finder favorites column, which refers to the following terminal message:
Last login: Fri Dec 5 15:01:10 on ttys002
/opt/X11/lib/libfreetype.6.dylib ; exit;

-bash: /opt/X11/lib/libfreetype.6.dylib: cannot execute binary file

[Proces voltooid]
More information may be found in the apple crash report, most of which to be honest is beyond my comprehension. The apple crash report is attached below. How could I get gr working on my machine? Your help is very much appreciated.

ps: anaconda is installed in user/anaconda

Version inconsistency between github and pypi
The latest release here appears to be 0.27.0, but it's nowhere to be found on pypi.
On the other hand, the latter offers a version 1.0.0 that lacks all the plugins.
Is this on purpose?

starting with a fresh environment:
pip (8.1.2)
setuptools (25.1.3)

error: $MACOSX_DEPLOYMENT_TARGET mismatch: now "10.6" but "10.11" during configureinstalling from source using pip and changing the macosx-deployment-target to 10.11 does work, so it would make sense to determine the OS X version dynamically during setup:
'.'.join(platform.mac_ver()[0].split('.')[:2])seems to work. Should I compile a PR?
Makefile/build process
The build process is full of odd practices
- use
prefix(mostly to replaceGRDIR) - prefer OS provided libraries (e.g. use
-lzinstead of bundling zlib) - prefer dynamic linking over static
- don't install libraries from each other. e.g.
make -C lib/gr installshouldn't install gks. - have separate install targets for C library vs python library vs julia library
- use
$(MAKE)if you need to call out to another makefile

Resizing issue with the following example plot
using Plots
gr()
plot(sin,(x->begin sin(2x) end),0,2π,line=4,leg=false,fill=(0,:orange))
Issue 1:
Moving the mouse towards the lower right corner of the GKSTerm window in the foreground changes the cursor shape to a two sided arrow.
Click and move the cursor to shrink the window, then release the mouse.
A black block appears within the drawing area.
Issue 2:
Select „Rotate by 90“. Resizing distorts the drawing.
interactive camera motion
is it currently possible to pan the camera with the mouse? there is a headline in the docs but i did not find anything so far?
STDCALL and fortran
cdecl is now prefered over the old stdcall convention on windows. stdcall is only useful for accessing the WINAPI functions. IMHO cdecl should be used per default for the Fortran interface.
Crash (MacOS El Capitan) if GKS application accidentally deleted
I inadvertently deleted the GKS window between calls (I sometimes do Command-Q rather than Command-W). (I know it's a dumb thing to do...)
