Charts now support POST requests

For example, the jar available for download doens´t contain LineChart.java
and so, without the .java, is impossible to make it work without
downloading the src.

Function CutNumber round badly float numbers.

Use GridLineBuilder constructor with value 9.0909

example new GridLine.GridLineBuilder(9.0909, 10);

Result for graph is 9, but should be at least 9.09.

You should preserve at least 2 places after point.

Solution could be

NumberFormat numberFormatClone = (NumberFormat) numberFormatEnglish.clone();// 
english format for point (czech format has comma)

// placesMin and placesMax could be as parameter or configuration
numberFormatClone.setMinimumFractionDigits(placesMin);
numberFormatClone.setMaximumFractionDigits(placesMax);

// result
return numberFormatClone.format(number);

placesMin and placesMax = 2, formats 9.0909 as 9.09.

update javadoc

Multiple output formats now supported, including PNG, GIF, JPG, and validation 
mode

What steps will reproduce the problem?

Create an XYLineChart with a pair of series and generate URL.


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

Expected comma for series separator in extended encoding set but get pipe.


What version of the product are you using? On what operating system?

svn trunk

Please provide any additional information below.

Patch attached.


Producing an XYImageLine chart generates invalid URL due to handling of 
auto and extended encoding.  Problem is two-fold:

1. Auto encoding for collections uses separator defined for Auto encoding 
and not the encoder for the appropriate type;
2. Extended encoding should be comma separated as per Google data format 
spec:

http://code.google.com/apis/chart/formats.html#extended

"A string where each two characters is a data point, and each series is 
delimited by a comma."

Scatterplots now support a trace line marker

What steps will reproduce the problem?

plot.setGridLine(new GridLine.GridLineBuilder(30, 15).segment(12, 
2).offset(25, 25).build());

Produces:

chg=30.0,15.0,12.0,12.0,25.0,25.0

length blank segment value is 2 not 12.  Also, where a float is ".0" then 
there is no point having this extra load on the URL.

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

Corrected and improved output:

chg=30,15,12,2,25,25

What version of the product are you using? On what operating system?

svn trunk

Please provide any additional information below.

Patch attached - I've corrected the length blank issue and ammended 
GridLine.CutSample to optimise the ".0" case.

I would guess that this is WAY too big for a issue, but just wanted to
deliver a heads-up that since Google App Engine doesn't whitelist the vast
majority of java.awt.*, and this library uses certain classes extensively
(Dimension, Color, etc), this library can't be used in a GAE environment. 
While it would be great if this library could be used without the AWT
classes, this is more to ask you to add your weight to the issues marked
"please whitelist java.awt.*" to the GAE forums...

To Reproduce:
Try to create any chart in a GAE environment

What steps will reproduce the problem?

I identify two problems.

1.
Can't add two independed data lines to line chart.
See LineChartDataAppender on line 169 and replace comma by pipe.
Probles is solved.

2.
Issue is with encoding char title or legend labels. There is a problem with
spaces. Solution is to replace space with + (by google rules).

New annotation marker added (chm=A)
New error bar marker added (chm=E)
New horizontal line fixed to a specific point (chm=H)
New box charts, also called box plots
Now support commas in the text string
Anchor placement now available for data value markers

What steps will reproduce the problem?

See attached code RenderSparkChart.java

As the library currently stands, you'll need to comment out the lines on the 
axis style that set line styles. 

This produces a URL that when rendered contains axis lines.


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

Current:

What version of the product are you using? On what operating system?

revision 189.

Please provide any additional information below.


A patch has been attached to allow specification of line style which when used 
with RenderSparkChart will produce the expected spark chart.

(I'm sure this used to be available at some point in the past!)

Text encoding is now called basic text format

The modifications in r148 mixed up the usage of &lt; and &gt; for < and >. 
&lt; was used for > whereas &gt; would have been right.

Should be fixed in order to not confuse the developers using the api.

Data sets are now called data series

New chart URLs supported ([0-9].chart.apis.google.com)

New formula images added

What steps will reproduce the problem?

    @Test
    public void testMissingValue() {
        final int[] series = new int[] { 19, -1, 20 };

        final IEncoder encoder = 
EncoderFactory.getEncoder(EncodingType.ExtendedEncoding);

        final String encoded = encoder.encode(series);

        Assert.assertEquals("e:AT__AU", encoded);
    }

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

org.junit.ComparisonFailure: expected:<e:AT_[_]AU> but was:<e:AT_[]AU>

Expect double underscore encoding for -1 value, but get single char which 
is against the data format spec:

http://code.google.com/apis/chart/formats.html#extended

Missing values are indicated with a double underscore (__).


What version of the product are you using? On what operating system?

Patch attached for JUnit test and fix.

Deploing an application with googlechartwrapper.jar on GlassFish4 will result 
in  

java.io.FileNotFoundException: FOO\lib\lib\swingx-0.9.0.jar (The system cannot 
find the path specified)
    at java.util.zip.ZipFile.open(Native Method)


What does it have to do with it? Is the swingx jar necessary? or can it be 
removed from Manifest.mf ? 

If i remove it- its working. Please bring it into an offical release. Its 
better than having to used a manually patched jar

Thanks

What steps will reproduce the problem?
1. Create a RangeMarker with a transparent Color, eg, new Color(255, 255, 255, 
0)
2. Assign this Range Marker to a chart
3. Attempt to generate the URL for the chart

What is the expected output? What do you see instead?
A Range Marker with transparent colouring is expected - instead the application 
crashes with an index out of bounds error in the getAppendableFeatures method 
of RangeMarker

What version of the product are you using? On what operating system?
Using version 1.1 of the googlechartwrapper on Windows 7

Please provide any additional information below.
This is caused by the same problem as issue #22.  The only difference is that 
in the case of issue #22 , the code is trying to cater for transparency, but 
fails.  In the case of the Range Marker, if the code worked it would not add 
transparency when required, however the root cause of the crash is the same.  
The fix for #22 needs to be applied to RangeMarker to prevent the crash and add 
transparency.

What steps will reproduce the problem?

de.toolforge.googlechartwrapper.Color c = new 
de.toolforge.googlechartwrapper.Color(255, 255, 255, 0);

String rgba = c.getMatchingColorHexValue();

Exception in thread "main" java.lang.StringIndexOutOfBoundsException: String

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

No exception and no output to std out.


What version of the product are you using? On what operating system?

revision 189, Win 7.


Please provide any additional information below.

As a work around, I replaced getEightCharacterHexValue with the following:

    public String getEightCharacterHexValue() {
        return String.format("%02x%02x%02x%02x", red, green, blue, alpha);
    }

New dynamic icons added

Axis labels now support custom formatting

Financial markers are now called candlestick markers

Underscore ( _ ) now means null in text encoding
