.. User charts can be scaled (lines, texts, markers, legend)
.. Plot area background color honours overview card color
when we're on an overview.
.. when adding a user chart to an overview make it span a couple
of columns and 3 times deeper than a metric tile.
NOTE:
There are two bugs that need to be squashed individually
and are related to user charts on overview:
1. Mouse event handling seems to be broken for user
charts in Overview.
2. User chart axis colors are always black when the series
are configured to use named colors.
