line chart qestion -- display data value

[itchytoes]

Hi --

 

On a lineChart, is there a way to display the value of the valueExpression on the chart itself over the point?

 

Thanks

You could achieve this via a chart customizer that would do something like

Code:

CategoryPlot categoryPlot = (CategoryPlot) chart.getPlot();
LineAndShapeRenderer lineRenderer = (LineAndShapeRenderer) categoryPlot.getRenderer();
lineRenderer.setBaseItemLabelGenerator(new StandardCategoryItemLabelGenerator());
lineRenderer.setItemLabelsVisible(true);

 

Looking at the JR sources, I see that we are not using the category datset label expressions for line charts. Doing that would make sense, and if you think we should do it please log a feature request [url=http://jasperforge.org/sf/tracker/do/listArtifacts/projects.jasperreports/tracker.feature_requests]here.

Hi --

 

Thanks! That worked like a charm. I had already fussed with the setItemLabelsVisible(true) to no avail, because I did not know I had to create one of these BaseItemLabelGenerator thingies.
