Remove the highlight on the Y Axis in JViews Chart JSF component

Technote (troubleshooting)


How to remove the highlight on the Y Axis in JViews Chart JSF component?


Upgrade to JViews 8.8
Set a <jvf:highlightInteractor> to your JSF Chart.
The Y Axis will also become highlighted when you hove the mouse over it.


The Y Axis highlight is a new feature for version 8.8

Resolving the problem

If you want to remove this highlight on the Y-Axis, you just need to write a subclass of IlvDefaultChartHitmapDefinition, and overwrite drawIntoHitmap() as follows:

public void drawIntoHitmap(IlvChart chart, IlvChartHitmapAccumulator
for (IlvChartRenderer renderer : chart.getRenderers()) {
if (renderer.isViewable())
drawIntoHitmap(chart, renderer, accumulator);

You then need to set this hitmap subclass to the hitmap property of you servlet in the web.xml.
