I have a workbook with two columns A(X) and B(Y).
I have plotted the red curve on the plot. The plot type is the 'Line+Symbol'.

As one can see the curve has some self-crossing points and
I need to fill the outside area of the curve.

My attempt: Plot Details -> Line -> Fill area under curve -> Exclusive broken by missing value.



I have problems with the area and axis.

Expected result is:


How to fill an area on the plot?

Hi,

You can fill layer background color with red and then fill “Exclusive broken by missing value” with white.







Thanks,
Amanda

Amanda, your algorithm is OK only for a curve without self-intersecting points (right), but I have a problem with the left graph that contains self-intersecting points.
