Using WaferMapDataset

[hubes]

Hi,

I'm using the class org.jfree.data.general.WaferMapDataSet to display wafer maps within a simple swing based application. By the way, JFreeChart is a fantastic set of chart library components...

But now I'm running into difficulties using the WaferMapDataSet.addValue(value, chipX, chipY) method to fill up the wafer map with data. First of all, is there any possibility to set the "reference die" to the for example left upper corner? The other thing I don't understand is how position/coordinate (0,0) is treated by the library - for some maps (0,0) is visible on the wafer, for other maps, like

Code: Select all

final WaferMapDataset data = new WaferMapDataset(15, 15);

data.addValue(50, 0, 0);

the position is not on the wafer map. Can anyone explain in detail how coordinates are referenced in the WaferMapDataSet?

Thanks and best regards
