Were you able to determine if this is a new bug or the same bug? I can't find a post on Sourceforge for this bug; can you point me to it?

Thanks for the prompt reply. import java.awt.Color; import org.jfree.chart.ChartFrame; import org.jfree.chart.JFreeChart; import org.jfree.chart.axis.NumberAxis; import org.jfree.chart.plot.XYPlot; import org.jfree.chart.renderer.xy.StackedXYAreaRenderer2; import org.jfree.data.xy.DefaultTableXYData...

but still on the chart we have a new color wich is the addition of the 2 where is stacked ... Sad I noticed the same thing. When using an alpha value on a stacked area chart, an overlapping of areas is shown. This occurs when a series not on the baseline has a zero value at one data point and a non...

Alberto, It generally helps if you describe your error in detail and provide code so people reading your post can see what's going wrong. Here's an example using a TimeTableXYDataset (any XYDataset is valid): NumberAxis yAxis = new NumberAxis(); DateAxis dateAxis = new DateAxis(); XYPlot plot = new ...

I'd like to draw value markers as an arrow instead of a line. The arrow would be at the edge of the chart. I looked through the code to see where markers are drawn (AbstractXYItemRenderer lines 896-911 in my case) and changed some code appropriately. I'm wondering if there isn't a better solution to...

From the code posted to fix the bug: ... // don't let anyone draw outside the data area ... What if you do want to draw outside the data area? In my case, I'd like to draw markers as arrows on the outer edge of the plot instead of as lines across it. If I change the clip, they draw fine. Is there an...

I'm using a CombinedDomainXYPlot that contains XYPlots using TimeSeriesCollections and a DateAxis on the domain. When I set the fixed autorange, the plots don't update. I can't figure out why. TimeSeriesCollection[] datasets = new TimeSeriesCollection[] { new TimeSeriesCollection(), new TimeSeriesCo...

How did I miss getPlot()? I don't know. Yes, much cleaner code; thanks for the correction.

Thank you for the added info, kanishk. I think I can help you. The problem is that the Renderer knows nothing about the dataset. The only time it ever is given information about the dataset is in drawItem, which is called when the chart needs to be repainted. (See http://java.sun.com/docs/books/tuto...

You need to be more specific about what kind of help you need.

I have a CategoryDataset. Suppose it has 3 categories, each with a different color. If I remove category 2, category 3 takes on category 2's color. My thought is the chart should maintain the category-color association, but color is assigned based on category index and not its Comparable key. Should...

Thank you.

Interesting idea sdd. I hope you find a solution. You might consider (I haven't even looked at trying this) extending BarRenderer. I want to do almost an identical thing: for a single category, I want the positive values to have one color and the negative values to have a different color. For ("row"...
