What's happened to my chart?

@seaviewer42 Difficult to answer such a broad question. What is it that you don't like about it?

@seaviewer42 

It works as designed, looks nice.

But it is so faint as to be almost invisible. It wasn't initially.

Based on screenshot only it's hard to say what you'd like to have and how it works actually. Perhaps you may provide sample file with comment which desired result shall be.

Thanks. After more trawling around I found that the "Chart type" had changed. Don't know how or why, but it is now clearly visible.
Anyway, thanks for response.

@seaviewer42 , glad to know you sorted this out, good luck!
