JavaScript Line Chart Formatting


I’ve put together a couple of line charts in a chart collection but they are both using the same color line, so it’s a little it’s a bit difficult to tell where one stops and the other begins. Is there any way to define what the color of the line is either from Charts/Reports or within Chart Collections, independent of interface-wide color schemes?

Additionally, is there a way to format the X axis? It’s a date field so it shows “10 Mar” but I would also like to give the day of the week for those dates (bonus points to anyone who can tell me how to display the full day name with dateformat() too).
