Reference lines with slope in scatter plot

[fpennisi17]

Hi,

it is somehow possible to add one or more reference lines with a slope (not parallel to X or Y axis) to a scatter plot, similar to the image below?

I would like to understand, at glance, how many points of the scatter fall in a sector.

One solution is to find a .PNG image online of a perfect 45 degree line with a white background.  Then, use this image as your plot area background with an "Fit" image style.  Not a perfect solution, but this displays a line with a slope equal to 1.  Example:

@fpennisi17 unfortunately, if it is not in the analytical pane then there is no way to add lines (afaik).

@fpennisi17 check the analytics pane and I think that is where you can add lines.

This is not the case.

The only available options I have are:

- Tendency line, which represents a linear interpolation

- Reference parallel to X axis

- Reference parallel to Y axis

- Symmetric shadowing, which provides only two areas and I cannot control the slope

This is why I was asking...
