I have another use case. I have a scatter chart for actual versus predicted values. The users are not interested in showing the trend line, but they do want a diagonal line thru center (x = y) - I was not able to create the line, but at least I was able to use the Symmetry Shading option under the Analytics tab. However, they also need error band mean lines, which is basically the standard deviation calculation. For example, if the standard deviation of the selected data is 105, they would like to see diagonal lines at 105 intervals on each side of x=y (up to 3 sets). The equation for the first set of lines would be y = x + 105 and y = x - 105, the equation for the 2nd set of lines would be y = x +210 and y = x - 210, and for the 3rd set y = x +315 and y = x - 315. I tried doing a screen shot, but it will not let me paste it from my clipboard.
Hi I'd like to be able to add multiple diagonal lines to a scatter plot, similar to the symmetry, horizontal and vertical lines with set gradients. ie. x=y - symmetry axis, x=2y, x=3y etc.. At pr...
