Thread: how to chose single color in design?

Attachment 38308

This is a screen shot...
I can choose design of above (sample is purple) but all of them are in range of very dark purple to very light purple and as you can see in red circle - light lines are very hard to see...

How I can choose a simple, solid, old-fashin black color for all lines

(Can take one by one and change them but there is hundreds lines and adding new... other words, I want to change all at once...)

You can not apply formatting to all lines at once. Code is the only quick way.

Hm, that's not solacing

Look on excel table (you have on sent items, too big to post it here)... I somehow manage to do that on first sheet (don't ask me how.. I think I mess something with a code )

But strange that you can't pick single color for entire chart...
