Issue with Dimensions Not Appearing on X-Axis of Column Chart in Looker Studio

[Solutionec_123]

I am writing to report an issue I am experiencing with a column chart in Looker Studio.
The problem is that  all dimensions are not appearing on the x-axis of the column chart , some dimensions are still missing from the x-axis. I would like to know how it would be possible to show all dimensions or if there is an option to add a scroll bar on the x-axis to accommodate all dimensions . While creating the visuals the resolution is very low and not clear .
while Dragging  and dropping the dimensions into visual the user interface is slow.
How can we resolve all these issues?
