seems can not set Gradient start from negative stop to zero..

[GoogleCodeExporter]

What steps will reproduce the problem?
1. i constructed a barchart which contains two data array..one is for negative 
values,another is for positive..
2. i need set two gradient to show negative and positive values..so i set as 
below:

renderer.getSeriesRendererAt(0).setDisplayChartValues(true);
        renderer.getSeriesRendererAt(0).setChartValuesTextSize(12);
        renderer.getSeriesRendererAt(0).setGradientEnabled(true);
        renderer.getSeriesRendererAt(0).setGradientStart(0, Color.CYAN);
        renderer.getSeriesRendererAt(0).setGradientStop(500, Color.BLUE);

        renderer.getSeriesRendererAt(1).setDisplayChartValues(true);
        renderer.getSeriesRendererAt(1).setChartValuesTextSize(12);
        renderer.getSeriesRendererAt(1).setGradientEnabled(true);
        renderer.getSeriesRendererAt(1).setGradientStart(-500, Color.MAGENTA);
        renderer.getSeriesRendererAt(1).setGradientStop(0, Color.CYAN);

What i wanna is from 0 to 500..the gradient from color cyan to blue and it's 
working.. but from -500 to 0 the gradient should from color magenta to cyan.. 
not working...can specify what the problem is??many thanks!

What version of the product binary library are you using?
I'm using the AChartEngine 0.7.0 binary build library.

Please provide a full class for me to test.
I think you are not using the RangeCategorySeries correctly. Please see an 
example here:

Do you have some complete code that I can use to replicate this issue?

I have the same issue as above, but with a single series passed to the Bar 
Chart and with the use of CategorySeries (instead of RangeCategorySeries). The 
package cannot render any negative bar chart values when r.setGradientEnabled 
is set to true (cannot see them at all on the chart). I am using my locally 
compiled JAR of AChartEngine 0.7.0.  I extracted and cleaned up the relevant 
class code and have attached it as a file (first post to this forum, not sure 
if i should have embedded the code or if there are code tags, etc). Let me know 
if you need anything else

I'm seeing the same issue on AChartEngine 1.0.0.
