How to set labels dinamically

[Marcial Atienzar]

Hello,

I take data from a BD. I need to know how to set labels inside the image. Is to say, I use bar to represent the image, and I need to put labels on top of this bars. Is it possible?

A lot of thanks,

Marcial Atienzar

Hello,

You can use the setValueLabelsVisible(true) so that the values are displayed inside the chart, on the datapoints.

The method is not implemented in each renderer.... I hope to provide some changes in order to widen the already existing work - perhaps end of next week.

However, I only planned to display values in a first time. I wondered to if it was more interesting to display kind of "tooltips"... but as I need a quick solution with values so I'll first write that !

So, the solution would perhaps be to write kind of ValueLabelGenerator class as the ToolTipGenerator, with some default labelTypes :
- valueOnly
- value + custom Text
- series value
- series category value
- ...
Any suggestion is welcome.

Regards,
Arnaud
