Line chart percent

I want to make a line chart that shows value percentage wise but I can’t find an option to do so.
If I try to do it with Stack series > Percent - It adds them up and shows the percent based on that which I don’t want to do.
Thanks in advance.

Not sure that I fully understand what you are trying to do. Are the numbers you want to plot already calculated as percentages or are they decimal fractions (0.25 instead of 25%)? It might be simpler and more straightforward to calculate your percentages as part of your spreadsheet and then plot those calculated values in an x-y scatter diagram.

Can you post an example of your data so that we can see what might be necessary to do? (Just edit your original question with the sample as an attachment.)
