I do not see any references to Wall objects inside Excel.Chart object???
Without Walls and Floors certain charts are not possible because hiding majorGridlines removes the very top and bottom line which I need to keep....modifying floor and back wall line styles gives me the look that I need but since they are not accessible via OfficeJS the project is getting burned.
Is Wall/Floor not yet supported in OfficeJS? Seems like a fundamental object...Any timelines when it will be available? I cannot even find it in preview API...and it is end of 2022...
