Frankyl, I am still a bit confused because every new image is slightly different from the previous ones. So maybe the following advice isn´t all that helpful:
If you want to left align charts that are in different ChartPanels, first you have to left align the ChartPanels! JFreeChart wont be really helpful with this task, since it is primarily a Swing layout issue. But let us assume that you have managed to solve that.
Then, you need to left align the plot areas of the two different chart. Here, the main issue is probably the length of the tick marks of the range axes of both plots. If you can guarantee that the tick labels of the range axes are of identical length, then the plot areas should be automatically left aligned as well (unless the labels of the two axes are visible and have a different font size, but this should be easily noticeable). If you need to show the tick labels, then it can be difficult to make them having the same length. However, if you call
Code: Select all
AxisSpace rangeSpace = new AxisSpace();
rangeSpace.ensureAtLeast(50, RectangleEdge.LEFT);
plot.setFixedRangeAxisSpace(rangeSpace);
on both XYPlots, then the plot will reserve the mentioned space (in pixels) for drawing the axes, even though the actual size requirement might be smaller.
