I had just found that out and was about to post it here

It would be nice to have a live drag mode though. Does the chart need to be constantly repainted during the live drag of a JInternalFrame?

Hi, I have noticed that a JFreeChart in a JDialog or JFrame doesn't get redrawn during the dragging of the window, however in a JInternalFrame the graph is constantly being redrawn while the JInternalFrame is being dragged. I have some fairly large graphs and this slows down the dragging of JInterna...

So it isn't a problem with your JFreeChart code, its your swing code. What LayoutManager is the panel using? is CENTER_ALIGNMENT the correct value for the LayoutManager? Are you adding the panel after or before you do pack(); setVisible(true); If you are putting the panel on afterwards, you can do a...

Where are you putting jPanel1? on a JFrame/JDialog?

JFreeChart is a Java library, not a .NET library.

If you want to use JFreeChart in a web application, you will need to use J2EE.

Hi, I'm looking for a way to move the label for a category on a bar chart to the end of a category (so the category labels appear to be inbetween the categories). This was easy to do with the gridlines by using: plot.setDomainGridlinePosition(CategoryAnchor.END); but I can't seem to find a similar m...

Hi, Im using XYPointerAnnotations to mark some points on a graph to the user. I would like to make the label on the XYPointerAnnotation printed vertically. The setAngle method sets the angle for the arrow, but I cannot find a method to set the angle of the label. I have tried using a seperate XYText...

you could try getting the tick size:

Code: Select all

NumberAxis yAxis = (NumberAxis)chart.getXYPlot().getRangeAxis();

double size = yAxis.getTickUnit().getSize();

rangeAxis.setUpperBound(maxValue+size); 
rangeAxis.setLowerBound(minValue-size);

forsey85

chart.getXYPlot().getDomainAxis().setLowerBound(double)

and

chart.getXYPlot().getDomainAxis().setUpperBound(double)

call getRangeAxis() for the Y axis

or

plot.setOutlinePaint(new Color(0,0,0,0));

to set it as a transparent colour

I've realised that it works fine so long as you don't use 0 for any of the dataset indicies. If you start from an index of 1 then its fine.

NumberAxis is a subclass of ValueAxis.

You should be fine I think

Oh yeh, I do have a bug in that code :lol: When I fix the bug however i get a slightly different problem. plot.setRenderer(1, new XYStepRenderer()); works correctly now, but plot.setRenderer(0, new XYStepRenderer()); sets the renderer for both datasets, when I only one it to set the renderer for the...

My source code isnt easy to post as it isn't very self contained, but I made a demo instead: import java.awt.BorderLayout; import javax.swing.JFrame; import javax.swing.WindowConstants; import org.jfree.chart.ChartFactory; import org.jfree.chart.ChartPanel; import org.jfree.chart.JFreeChart; import ...
