need advice regarding datasets flot jquery
Hi I have 2 questions regarding the script below.
Question 1: Why is only Test1date, Test1time, Test1Test1modules etc.... getting diffrent colors, while the colors of Test1date, Test2date, Test3date etc... getting the same color, and how can I change this??
Question 2: I Only want to print out checkboxes for "failed" and "cover" below, but how do I check if a key contains anything with "cover" or "failed"?? As for now I check if a key is equal to "Test3failed" or "Test2cover". But I only want to check if key==something containing "cover" or "failed" Thanks in advance =)

1) You are getting the same color for the objects because you are setting var i = 0; at the start of every loop, move it to outside of the loop expression.
2) You can check if a variable contains another by using .indexOf. For example, to check if key contains "cover" you can do: if (key.indexOf("cover") > -1) { ... }
