Hello, I'm developing an application in which I have Charts representig data over time, the common date intervals are weeks. What I would like to achieve is that when the Charts are initially shown, there are only the first 16 weeks that are shown. So basically, I would like to zoom on those first 1...

Thank you for your help. Seems like my colleague managed to solve the problem by writing a custom renderer.

Does nobody know? Or is something unclear? Please help me

I have a Graph which shows time-based data usind a XYPlot. I use a TimeSeriesCollection with one TimeSeries for each datarow I have to display because of my intern metadata definition and because I implemented the possibility to make single series (un-)visible using checkboxes. So each Collection ha...

Hi there, I wrote a little application to visualize some data and put the whole thing into a jar file. My chart is a combined chart that contains XYItemRederered TimeSeries and ClusteredXYBarRendered data.Now when I exceute the jar file normally, everything is shown as I want it to look like: the ba...

You have to create a TimeSeries for each 'line' you want to show and add it to your TimeSeriesCollection.

Thank you very much, I didn't know I had to do that and read over it looking at the demo code. Sorry.

Hello, I'm trying to make a chart that contains a XYPlot using TimeSeriesCollections as datasets. Now I wanted to try to set one renderer of the Collections to StandardXYItemRenderer and the other one to XYBarRenderer(). So I did that, compiled it, tried to run it and I've got a NullPointerException...

I would suggest to use the BoxLayout for that. Have you tried to repaint the panel that contains the chartPanels?

What about removing the series you want to hide, save it in a TimeSeries variable (or a Vector if you have more than one) and then just adding it again when you want it to be shown? then, you'll only have to repaint the chart.

It would be easier to tell if you showed some code, but I think it's you messing something up when you do something with you dataset.

Hello,


try this:

for Ä: '\u00C4'
for Ü: '\u00DC'
for Ö: '\u00D6'
for ä: '\u00E4'
for ö: '\u00F6'
for ü: '\u00FC'

I hope this works

There are plenty of example programs (with code) in the zip/tar.gz file you downloaded. Look in the jfreechart file in path: /src/org/jfree/chart/demo. I think you'll find what you need there.

Try using the setInnerGap() and setOuterGap() methods of the StandardLegend class.

Get the renderer you want to use and then use the setToolTipGenerator() method.
