Charts personalization

Good afternoon,

I had two quick questions regarding charts:

- Is it possible to order the bars in a bar chart from smallest to biggest amount/bar, or vice-versa? Right now I can only manage to order it by the name of each bar, but not by their size.

- Is the chart color scheme customizable in any way? For example red and light blue are the standard colors in a pie chart with two data points. Can those be changed at all?

Many thanks for your help and have a great weekend,

Giovanni
