# Why do I always have a grey corner on my plot? [closed]

I have encountered a very wired plotting issue:

I had a script to plot 6 triangles together in one graph as below (first figure). However, as you could see there are always two grey parts in the corner that come from nowhere. When I simply plot these two triangles, they look perfect as in the second & third figure.

Could anybody tell me what mistake I have made? Thanks so much in advance!

• Clipping. Show a MWE (i.e. code that produces the problem) for more advice. Or look it up in the documentation for Plot and post your own answer. – Michael E2 Aug 18 at 15:04
• Add PlotRange->All to each of your plots, once they are calculated you can't adjust it above what was set. – Kuba Aug 19 at 9:16
