Rendering Gradient Fills

[raumaduth]

Hi,

I am trying to fill an area chart with a gradient fill, (similar to how the barchart renderer does a gradient fill with the gradient paint transformer). In essence i am defining the max and min values of an area chart and filling defining a gradient fill for rectangle enclosing the graph. My shading goes off the moment i resize or zoom into a chart. is there any way to prevent this from happening. I noticed with the bar chart renderer, the setGradientPaintTransformer method is set once when setting the renderer properties, and the shading is kept perfectly on zooms and resizes. How can i do this for an XYArea Chart.???

Please help..

You need to modify the (fixed) control points for the GradientPaint once you know the dimensions of the chart (which is not until drawing time). The bar renderer does this as it draws each bar. You could perhaps do this in the initialise() method in the area renderer, since you only want one gradient.
