SWT -- Tooltips and plot Orientation

[marc0]

Hello everyone,

I currently am using JFreeChart 1.0.13 to develop an Eclipse plug-in that will generate plots, using the ChartComposite class within a JFace Structured Viewer.

I have found out that whenever I set the plot orientation to horizontal during runtime, tooltips will not show up at all, unless I set the plot back to vertial. This is happening whether I use an XY chart, bar chart, etc..

I wouldn't want to say that this is a possible bug yet, but is there a known workaround, or am i doing it wrong?

Here is an example code I used (and modified a bit), I do not remember the source (it may probably be this forum!). It is not a JFace application but if you set the plot orientation to vertical during runtime, this 'bug' will show up.

Code: Select all

import java.awt.Frame;
import java.awt.GridLayout;

import org.eclipse.swt.SWT;
import org.eclipse.swt.awt.SWT_AWT;
import org.eclipse.swt.layout.FillLayout;
import org.eclipse.swt.widgets.Display;
import org.eclipse.swt.widgets.Shell;
import org.jfree.chart.ChartFactory;
import org.jfree.chart.ChartPanel;
import org.jfree.chart.JFreeChart;
import org.jfree.chart.plot.PlotOrientation;
import org.jfree.data.general.DefaultPieDataset;
import org.jfree.data.xy.XYSeries;
import org.jfree.data.xy.XYSeriesCollection;
