I was using ArcMap 10.3.1 and having issues with inserted charts not exporting symbology (color, icons) correctly. Thus, I upgraded to ArcMap 10.5.1 and installed patch hoping that Esri fixed this issue, but I am still having the same issue.
It will be clearer if you see the attached chart in my layout compared to what it looks like when it gets exported.
The work around I found is draw a box and text and then place the box and text where they are not showing up on export, but this is extremely time consuming.
This is really frustrating and I can't imagine that nobody else has seen this issue. Any ideas what's going on?
