Is there a way to make the classic graph or chart completely one colour, i.e. remove any embossed effects? If possible i would like to have been able to remove or paint black the lines shown in my attached png. I’ve tried painting them but cant get them to vanish!
I opted to mask those lines using black rectangle decorations in the end! if anyone knows of a neater solution, i'd appreciatte a heads up.
You can make it transparent by clicking the T that is available in the Color palette at the right top corner as shown.
Here is a good resource, look at the video on recoloring graphs:
