Linechart viewfinder uses wrong colors if some series are disabled

[fufas]

Let's say you have a line chart with a view finder (focus). You specify colors ['red','green','blue','orange'].
Your 4 data series draws fine, then you click on the 'blue' one in the legend. So it disappears from the chart, but the blue color is still being used in the view finder (orange - the last one - isn't). So at that moment view finder colors don't match the chart colors.

Seems like a legit bug. Probably the view finder axis it's not being updated. I'll take a look.
