Currently, the Bar chart is limited to show 10 Dimensions.
However, when the Dimension is e.g. "Country" you can easily go over the limit and therefore the chart will not show the complete data.
A solution might be to group remaining Dimensions as the "Other".
Thank you for submitting your request.
One way to show more than 10 Dimensions on a Bar chart is selecting ''Dimensions'' for x-axis (see screenshot), if this kind of report works for you.
