Legend spacing not proper

[bharat-mukheja]

The legend takes a lot of space from the graph even when not coinciding. e.g. look at the below graphs -

It shouldn't need that much space just to lay out two values. But I guess the legend is being processed independent of the graph hence the graph doesn't know about the spacing requirements. What can be done here is that.

As an extension, the spacing of the graph itself should be improved. For example, the below -

this is legend set as horizontal

this is legend set as vertical

No other change was done to the pie graph. Seems like the legend wants to be vertical always, but when asked to be vertical specifically, it takes extra space from the graph canvas.
I think we need a better spacing algorithm than this.
