Missing Align in ChartLegendOptions

[tomas-kucera]

There are two attributes for positioning legend:

• position - implemented - sets whether the legend is top, bottom, left, right
• align - not implemented - sets the alignment of the legend - start, center, end

Solution: just add to the begging of class ChartLegendOptions:

external String /*'start'|'center'|'end'*/ get align;
external set align(String /*'start'|'center'|'end'*/ v);

and

String align,

to the top of the external factory ChartLegendOptions at the bottom of the class.

I guess we can close this as it was completed.
