hello,
After I finally found where to look at to output my charts I ran into an
exception. I am trying to use the device renderer to output my chart to
a file.
And this is the exception:
org.eclipse.birt.chart.exception.ChartException: $NO-RB$ Source value
can not be null
at org.eclipse.birt.chart.factory.Generator.render(Generator.ja va:1214)
Here is the relevant source code:
--snip--
final PluginSettings ps = PluginSettings.instance();
try {
dRenderer = ps.getDevice("dv.GIF");//$NON-NLS-1$
} catch (ChartException ex) {
ex.printStackTrace();
}
BufferedImage img = new BufferedImage(500, 500,
BufferedImage.TYPE_INT_ARGB);
Graphics g = img.getGraphics();
Graphics2D g2d = (Graphics2D) g;
dRenderer.setProperty(IDeviceRenderer.GRAPHICS_CONTEXT, g2d);
dRenderer.setProperty(IDeviceRenderer.FILE_IDENTIFIER,"C:\\ChartImage.gif ");
Bounds bo = BoundsImpl.create(0, 0, 500, 500);
bo.scale(72d / dRenderer.getDisplayServer().getDpiResolution());
Generator gr = Generator.instance();
try {
gcs = gr.build(dRenderer.getDisplayServer(), chart, bo, null, null , null);
gr.render(dRenderer, gcs);
} catch (ChartException e) {
e.printStackTrace();
}
--snip--

hello,
I found out the following. If I use the serializer.write method on the
chart before I render it with the device renderer, this exception
occurs. Otherwise I could output it on the device renderer. Same for
charts that I have read with the serializer.
But how can I read a chart representation from an xml representation now
and output it to a renderer?
thank you for your help,

You need to bind the runtime dataset again after you
serialized/deserialized the chart model. the serialization will
eliminate all the runtime information including the runtime dataset.

Thank you for the tip. I already thougt of something like that. But how
can I do this? So far I was only using the chartwizard with my custom
IDataServiceProvider. I dont know what I need to bind now.

You need to implement the interface IDataRowExpressionEvaluator, then
use Generator.bindData(). The IDataServiceProvider is only used by the
Chart Builder at design time.

Thank you for the tip... I am now using the bindData method from the
UiHelper class (or similar) to bind the Dataset with the
IDataserviceProvider.
I just got confused by the IDataRowExpressionEvaluator but it works fine
now!
