[Engine-devel] [UX] how to design a bar/line chart?

Hi all, There is a feature request [1] which aims to replace the resource utilization graphs (for example the cpu utilization from vm tab) by some which shows not only the actual percentage which is not so useful by some monitor graph. I have the following concerns: - I can think of a bar chart or a line chart and not sure what would be better. - Not sure if replacing the current chart with a bar/line chart would make the statistics readable enough. Maybe if you hover the chart it could pop up a bigger version of the chart? Or not needed? - Would it be enough to have it in one color? Or should it be something like "the bigger the utilization the more red"? Please advise from the UX perspective. As soon as the final design will be a bit more clear I will provide a feature page. Thank you, Tomas [1]: https://bugzilla.redhat.com/show_bug.cgi?id=803251
