yannrichet / jmathplot Goto Github PK

-Does JMathPlot have a GPL style license making the library free for commercial 
use and inclusion
(but not reselling)?

-Where are the Javadoc files for JMathPlot?

-May JMathPlot produce graphs, charts, plots which are fully 3D rotatable?

-May JMathPlot produce one object for the final chart, which includes all data 
and metadata
within the plot, as a fully rotatable JAVA3D Object? How is this acheived?

-May JMathPlot produce 2D or 3D graphs as jpeg, bmp, gif, png file types 
automatically?

What steps will reproduce the problem?
1. Try using this library from project that uses Apache Maven 2+ as build tool
2.
3.

What is the expected output? What do you see instead?

I want the numbers on axes to be more visible.

What steps will reproduce the problem?
1. Run the histogram example from the wiki
2. Notice that it is consuming an entire CPU core...

What is the expected output? What do you see instead?
It shouldn't be constantly redrawing

What version of the product are you using? On what operating system?
Latest code from SVN 

Please provide any additional information below.

It looks like the problem is that HistogramPlot2D.plot() calls:

draw.canvas.includeInBounds(bottomLeft[0]);
draw.canvas.includeInBounds(topRight[XY.length - 1]);

..which in turn call repaint() and force a redraw of the chart, hence looping 
infinitely.

Skim-reading the code, I guess the same applies to ClodPlot2D and 3D too.

What steps will reproduce the problem?
- Plot2DCanvas:
When providing two arrays, one for X and for Y, each of length 2, to the 
Plot2DCanvas method "addScatterPlot(String, Color, double[], double[])", then 
the columns don't get merged to create an array of x-y pairs, but merely 
returned (see method "convertXY" in org.math.plot.canvas.Plot2DCanvas class). 
This means that the two arrays, listing x and y separately, get treated 
incorrectly as two x-y pairs instead.

- Plot3dCanvas:
When providing three arrays, one for X, one for Y and one for Z, each of length 
3, to the Plot3DCanvas method "addScatterPlot(String, Color, double[], 
double[], double[])", then the columns don't get merged to create an array of 
x-y-z triplets, but merely returned (see method "convertXYZ" in 
org.math.plot.canvas.Plot3DCanvas class). This means that the three arrays, 
listing x, y and z separately, get treated incorrectly as three x-y-z pairs 
instead.


What is the expected output? What do you see instead?
I've attached two source files that solely depend on the jmathplot library. 
Both of them will pop up two JFrames, one with the correct display and one with 
the incorrect display.
In the 2D case, it is immediately apparent, since the incorrect one displays 
the same min/max for the X and Y axes (10-50) instead of X:10-12 and Y:45-47.
And in the 3D case, it is easiest to turn them in such a way, that one looks 
onto the X-Y plane (= bird's view). The correct display has the axis ranges 
X:10-12 and Y:45-47, the incorrect one X:10-100 and Y:10-200.


What version of the product are you using? On what operating system?
Latest version from subversion/trunk. Linux (Centos 5.5 64-bit). Java 1.6.0_20 
64-bit.


Fix:
I've attached a patch file (plot_canvas.patch), generated from the current 
trunk in the subversion repository, that fixes this problem.

Currently distributed jmathplot.jar is not signed. This causes problems for 
using it with java 6_10 (browser asks user if he/she wants to block not signed 
application form execution).

What steps will reproduce the problem?
1. include the pckage

What is the expected output? What do you see instead?
expect it to the exist and for the tutorial to work as planned; it does not 
exist, so cannot import anything from org.math.array.

What version of the product are you using? On what operating system?
2009 version, Windows 8

Please provide any additional information below.

What steps will reproduce the problem?
1. Plot2DPanel.addLinePlot("", new double[]{1,2,3}, new double[] {4,5,6})
2. Plot2DPanel.addLinePlot("", new double[]{1,2}, new double[] {4,5})
3.

What is the expected output? What do you see instead?
according to the arguments (String, double[] X, double[] Y), #1 should be 
plotting the follow data points(1,4), (2,5), (3,6) and #2 should plot (1,4) and 
(2,5).

This does not happen for #2. #2 plots (1,2) and (4,5).

Rotating the axislabel misalign the line plots. 
I'm adding some line plots to my graph and want to rotate the axis label of the 
y-axis.

Code Used: 

panel.getAxis(0).setLabelPosition(0.5, -0.15); 
panel.getAxis(1).setLabelAngle(-Math.PI / 2);
panel.getAxis(1).setLabelPosition(-0.15, 0.5); What is the expected output? 

OS: Windows XP SP3
JAVA: 1.7

What steps will reproduce the problem?
Use Plot2DCanvas insted of PlotPanel.

I was using PlotPanel with the method:
    addLinePlot(String, double[], double[])

When I changed to Plot2DCanvas it gave me a compilation error.
I Guess Plot2DCanvas should also have that method.

    // add a line plot to the PlotPanel
    plot.addLinePlot("my plot", x, y);

    // put the PlotPanel in a JFrame, as a JPanel
    JFrame frame = new JFrame("a plot panel");
    frame.setContentPane(plot);
    frame.setVisible(true);

    double[] x = { 1, 2, 3, 4, 5, 6 };
    double[] y = { 45, 89, 6, 32, 63, 12 };

    Plot2DPanel plot = new Plot2DPanel();

    plot.addLinePlot("my plot", x, y);

    JFrame frame = new JFrame("a plot panel");
    frame.setSize(600, 600);
    frame.setContentPane(plot);
    frame.setVisible(true);

}

What steps will reproduce the problem?
1. generate a plot
2. click on the "save graphics as a .PNG file" button
3. enter name, select location, and choose "save."

What is the expected output? What do you see instead?
expected: plots are saved as .png
instead: plots are saved as .file
