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.

ImageMapUtilities improvement

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...

PieChart Label Colors

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?

Cheers,

selectively display DomainAxis values

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...

getting a list of entities for a subplot

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 ...

StackedXYAreaChart for non tabular/rectangular data

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...

set Minimum tick unit count

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...

Best way to display percentages on a pie chart

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...

Grouping minor/insignificant values of a Pie Chart

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...

XYStepAreaChart different seriesOutlineColors to seriesFillC

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. ...
