Legend alignment

[guyom]

Hi guys,

I try to generate a StackedBarChart, but the legend is too long to be written on just one line and I don't know why the second part of it isn't left aligned. An illustration :



We can see that " souscrites en janvier" is centered although I set :
legendTitleNew.setHorizontalAlignment(HorizontalAlignment.LEFT);


I need you're help


Thanks !

I think there is no API method to fix this. The LegendTitle class is using a LabelBlock object to represent the label, and within this class a TextBlock is used. The TextBlock has a method setLineAlignment() which you could use...unfortunately it is not nicely exposed by the API. I suggest you try setting it within the LabelBlock constructor and see if it has the desired effect - something like this:

this.label = TextUtilities.createTextBlock(text, font, this.paint);
this.label.setLineAlignment(HorizontalAlignment.LEFT);

If that works, then the API needs changing to allow the LegendTitle to pass the required alignment down the chain. I don't have enough time to look at this more closely right now sorry.

Hi David,

I have been having the same problem as has many other developers with long legend text and having it centered as a default alignment. The patch to the LabelBlock class works as expected and will place the label text with left alignment within the block.

The company I work for, CA Technologies, would rather use a supplied jar maintained by the developer team than modify the existing API and maintain it ourselves.

Is there any time frame to provide a more general solution since this is an issue that has been around for quite some time? Perhaps a method in the LegendItem class that takes an Alignment parameter and passes it onto the LabelBlock class?
