  Bars with Marks

Hi Peter,

I have a bar layer with two data sets. For every bar I need a mark line. I use the box-whisker layer to add the mark lines. For every x axis value are two bars and two mark lines. My problem is that the mark lines cross the two bars but they should cross only the bar to that they belong.

Regards
Gerrit

Hi Gerrit,

You may use Layer.alignLayer.

I suggest something like (in Java/C#):

//align myBoxWhiskerLayer0 with data set 0 in myBarLayer
myBoxWhiskerLayer0.alignLayer(myBarLayer, 0);
myBoxWhiskerLayer0.setDataWidth(c.getPlotArea().getWidth() * 0.4 / noOfBars);

//align myBoxWhiskerLayer1 with data set 1 in myBarLayer
myBoxWhiskerLayer1.alignLayer(myBarLayer, 1);
myBoxWhiskerLayer1.setDataWidth(c.getPlotArea().getWidth() * 0.4 / noOfBars);

Hope this can help.

Regards
