3Std.Dev limits on parellel line chart with multiple categories

[gsksarepta]

I have this parellel line chart in Power Bi desktop with 3 separate categories on X axis and multiple runs and their yields on Y axis displayed in different colors. I want to add 3 std. dev lines for each of this category as upper and lower limits to this same chart. Because each category have its own std.dev limits, it wont be a straight line but follows the trend of how most other runs are aligned. Can I know how can I display the +/- 3 std.dev values as upper and lower limits to this chart? Additionally an average line as well.. Thanks in advance.

No, this gives me the static average line. Here I need average line with different average (and Std.dev) values for each category on X axis

Hi @gsksarepta 

For average lines, you can switch to below ribbon and try "Average line" there. 

For 3 std. dev lines, currently I cannot imagine what it should be like on the chart. If every category has upper and lower limits, it seems to be two points for every category on the line chart.
