We have a requirement to render charts based on there locale, e.g. if the chart is displayed for an Arabic user, the chart should be rendered "right to left".

What does this mean for a pie chart, if the legend is normally displayed on the right hand side, then for an Arabic user the legend should now be positioned on the left hand side.


I have added script to change the legend frame colour, the border colour, to set the legend to visible/invisible, see below, they all work fine.

But the line of script to move the legends position from right to left does not work?

I guess is something simple like calling a re-paint method or something, if this is not possible in Java script is it possible by writing a Java Event handler/Adaptor?

Regards.
Anthony.

Here is the output of the debug lines (before the chart position is right, after
we update the setting to left, but the legend is still on the right!!!)
current setting=Right
current setting=3
updated setting=Left
updated setting=2

Have you tried grabbing the chart in the beforeFactory and changing the position there? Let me know. Also let me know your BIRT version and I'll try it out.
