[Calc] Remove data points from chart

I create a chart (XY Scatter) from two columns of data (corresponding to X and Y axis). Now from this chart I want to manually remove some outlier points. How can I do that please?

I tried to click on the point to be removed and then press the Delete touch but that does not work (Error: “This function cannot be completed with the selected objects”).

Thank you for your help.

Delete the offending points from your y column, or copy the y points to a new column, delete the “bad” points from the new column and plot that.

Just hide the lines containing the undesired points. This should suffice and you don’t need to delete any of your original data.
