Grouping together related datasets in linechart

[AScherp2371]

I'm currently working on a project where I have objects that consist of multiple datasets for the Y-axis values (the x axis values are always the same interval), that looks as follows:

{
name: "measurement 1",
resultSetA:[10, 25, 65, 75, 54, 30, 10],
resultSetB:[10, 22, 34, 40, 37, 28, 12],
resultSetC:[2, 5, 9, 12, 8, 4, 3]
}

What I'm looking for is for the lines to be grouped by their parent object: same line color, style, but I also need them to share the same legend entry(to make filtering easier).

Has anyone tried creating something similar to this?
