how to add more than 3 lines in chart

[pmairoldi]

Add a forth dataset.

[rajeshm20]

I have but...Chart doesn't show the 4th line..but only legend only showing up

[rajeshm20]

is there any limit for number lines in Chart?

[pmairoldi]

Shouldn't be. What is the dataset for triglycerides?

[rajeshm20]

tcTriGlyc: ["150", "170", "166", "180", "230"]
tcCholstrl: ["195", "178", "189", "170", "188"]

[rajeshm20]

TriGlycerides: ["150", "170", "166", "180", "230"]
Cholesterol: ["195", "178", "189", "170", "188"]

I would assume that you correctly created the data set but have not added the values correctly. I can't know without seeing the code.
