Get graphics from VisualizationComponent rapidminer

Hi,

How to get graphics or image from visualization component??
i have visualization component the same i am passing to JFrame tree is displaying in standalone app.
but in WebApplications it is not coming as Jframe will work for standalone apps.

Component visualizationComponent = gr.getVisualizationComponent(model, ioResult);
visualizationComponent .getGraph()...............>returns null even though visualization.isDisplayable() returns true.
if i use renderer where it will render ?

i want to get the tree and display in Application by setting some variable.

Thanks in advance

Renderer renderer = RendererService.createRenderer(result, "Graph View");
Reportable reportable = renderer.createReportable(result, dummy, imgWidth, imgHeight);

final BufferedImage img = new BufferedImage(imgWidth, imgHeight, BufferedImage.TYPE_INT_RGB);
Graphics2D graphics = (Graphics2D) img.getGraphics();
graphics.setColor(Color.WHITE);
graphics.fillRect(0, 0, imgWidth, imgHeight);
double scale = Math.min((double) imgWidth / (double) preferredWidth, (double) imgHeight / (double) preferredHeight);

Hi,

my codeblock from the linked thread paints the tree on any given Graphics object. Please consult Google for details on how to use the graphics context in Java.
