Gridlines in chart

[Guest]

How can I change the color of certain gridlines "not" all gridlines? For
example, with a control chart - a yellow line for mu - 2sigma and a blue line
for mu - 1sigma?

Rather than change grid line color, add a horizontal line at the value you
want.

I have an example control chart at this link.

I explain how to add a horizontal line here.

Hi,

You can not format individual gridlines. The work around is to add extra
data series for draw the line. Here is a collection of examples to
help you.
