Sophie Osborne Posted January 17, 2022 Share Posted January 17, 2022 I have made a scatter plot that I have added a straight line fit to. Additionally, I would like to add a straight line at P10 and P90, but I don't want it to be just vertical or horizontal (i.e. it needs to have a slope). I'm assuming I would use the curve draw feature, but I do not know what the expression would look like to create these lines. Thank you. Link to comment Share on other sites More sharing options...
Gaia Paolini Posted January 17, 2022 Share Posted January 17, 2022 P10 or P90 are similar to e.g. a Median line. If you take it on all data, it is a single value. Can you elaborate on how you need this to be calculated and maybe give a visual example Link to comment Share on other sites More sharing options...
