I don't see any way to change chart colors in the Intelligence Dashboards or to be able to edit the X and Y Axis legends. It just defaults to shades of blue and green and puts in whatever the filter name is for the Legend Text
And when I customize the dashboard layout, it is difficult to size the widgets. I can move widgets around, but they seem to stick to a predetermined grid spacing and I find it difficult to size the widgets and place them where I want. I was just trying to find out if there is some way to manipulate the widgets to fit better?
