XY Chart: Identify chart lines (with labels or legend etc.)

[ebugden]

There is no easy way to identify which line is which. There is no visible legend for lines. (Only possible to know which is which by checking and un-checking the box.)

Some options for identifying lines:

• Label lines directly
• Add legend for line colours
• Write label text in the line colour

Disk I/O has a legend to the right of each checkbox label, but because the width of the section can't be adjusted, the legend is only visible if the screen resolution is large enough.

Hovering cursor over xy-charts would show a tooltip with the legend: The legend labels each line color, but does not indicate the process name. @bhufmann Should this issue be closed?
