After further review I was a bit premature to claim victory. Each graph is in it's own range. I want them to be the same range, so the change is visible. The auto-scaling that is calculated per graph should be applied to all graphs in the combined. Exampe: The scale for both graphs should be 0 - 312...

Doing the above, as you suggested causes each plot to have its own range. That is not acceptable. The magnitude of change is skewed when you allow each plot to have a different scale.

I'm trying to create a CombinedDomainXYPlot, but am having troubles getting it to scale correctly. It seems like the scale of the last XYPlot added wins and all others are ignored. Here is a simplied version of my code. Any help is much appreciated. import org.jfree.ui.ApplicationFrame; import org.j...

Worked great! Thanks! btw... This is how I implemented it... where mouseX & mouseY are used in the main panel. private void evaluateScreenMouseXY(XYPlot plot, XYDataItem di) { ChartRenderingInfo info = this.chartPanel.getChartRenderingInfo(); Rectangle2D dataArea = info.getPlotInfo().getDataArea(); ...

Is there a way to get the X and Y values for the XYPlot's crosshair location? Read carefully before you answer. plot.getDomainCrosshairValue() gives the value for X in the Dataset, but I'd like to know the X value on the panel to position some text relative to the crosshair location. It'd be nice if...

Is there a way to tie the arrow keys to iterate through graph plots? Similar to the side effect of the slider in 'Crosshair Demo 1'. I could just use the slider, but I'm having a hard time figuring out how to find out what item in the dataset I've selected. The slider is tied to the dataset.getItemC...

move the chartPanel.addChartMouseListener(new org.jfree.chart.ChartMouseListener() {... to the constructors chartPanel.

You've created an extra chartPanel in the createChart method that is not necessary.

Can I disable single click response for the crosshairs?

The crosshair values don't mean anything when the chart is single clicked ( it's all over the board ).

That'd be awesome! Please repost to this when it's available.

Is there a way to force the crosshair value to update?

I'm plotting 2,000 points. I was using the ChartProgressListener, but it seems to bog down the CPU with this many data points.

I'm using an XYChart with use of the crosshair functionality which matches closely to CrosshairDemo4.java. This example states that the crosshairs will lock on the nearest data point. The Crosshairs visibly migrate to a valid point, but the double x = plot.getDomainCrosshairValue(); double y = plot....

I'd like to change the background color of the XYTextAnnotation, so the text is a little more easy to read.

Thank you for your help.

I'd really like to have a look at the source code as well.

Please....
