Areas with the same coords will be removed from map element.

It doesn't matter if the areas overlap. They can stay.

I am only talking about areas that are identical!
An area would be identical if all their coordinates are equal.

I have noticed that the ImageMapUtilities will produce multiple map elements for identical coords. In the method: public String getImageMapAreaTag( ToolTipTagFragmentGenerator toolTipTagFragmentGenerator, URLTagFragmentGenerator urlTagFragmentGenerator) { you could put the coords into a Map, or a Se...

Okay,

with my limited French, I gather that this means it is not yet possible
to set different label colors for different Pie Segments, non?

Does anyone know of a way to do this otherwise?

Hi, I am rendering a DefaultCategoryDataset using a a BarRenderer and would only like to display the very first and very last Category Label (i.e. the label for an actual Bar). Is it possible to use a specific Axis class to do this or is the only way to leave the values out of the dataset to begin w...

Hi, I am rendering two XY line charts using a CombinedDomainXYPlot. I would like to render tooltips and URLs on the image that: 1) Extend the full length of their Range Axis 2) Extend back to the point before. This is so that the entire plotarea is 'clickable'. I extended the ImageMapUtilities.getIm...

Hi, I am hitting similar walls with image map generation not being flexible enough. My problem is that I would like to overwrite the default image map areas for a particular point. For example, I would like a line chart to be clickable on the entire X-Axis, and not just at the point on the line. If ...

Hi,

I was wondering what the easiest way to implement a StackedXYAreaRender
that takes a standard XYDataset instead of a TableXYDataset would be?
i.e. The data to render is not nescessarily rectangular.

Any suggestions would be great.

Cheers,
Nick.

You said you specified your own standard tick units - try adding a smaller tick unit to your collection. Right, but when I add the tick units, I do not know the size the of the graph, size of the labels etc. All this gets done at renering time in NumberAxis in the method: calculateVisibleTickCount....

No. The auto tick unit selection mechanism will choose the smallest tick unit---from your collection of "standard" units---that it can display without the labels overlapping. The chart just looks really wierd with only one tick-unit value displayed. This is usually 0, and then punters have no other...

Hi, I would like to know if it is possible to set the minimum amount of TickUnits shown on a ValueAxis in a XYPlot. I am using my own StandardTickUnits, via the setStandardTickUnits method on the ValueAxis. I noticed that then calculateVisibleTickCount in NumberAxis always returns 1 for a certain se...

thanks, that is perfect.

Hi, What would the best way to display to the percentages, as well as the values of segments in a Pie Chart be? I have a lot of data, and do not nescessarily want to to iterate twice over the dataset to calculate these percentages. I am sure Pie Chart calculates this already to draw each segment. Ch...

Hi, Has jfree chart implemented a heuristic that will group segments of a pie chart that are too small or insignificant to dedicate an entire segment and label for? For example, say I have a dataset of 100 values to draw, I would only like to show the top 10 values separately. The others would be gr...

Does anyone know how to do exactly the same, but instead to plot an XYStepAreaChart ? I have the same problem, in that using the current implementation of XYStepAreaRenderer, whenever I call setSeriesOutlinePaint() or setSeriesFillePaint(), the default colors are always used instead of those I set. ...
