I am using a bar chart and maxing the size of the bars so there is no gap between the dimensions being measured.
But when I put the sheet into a dashboard, small white gaps appear between some of the dimensions, this changes between the dimensions whenever I adjust the size of the dashboard.
How can I get rid of these white gaps?
The container on your dashboard containing this sheet is set to 'Entire View' display.
Go into the Bédoin sheet and set it to 'Entire View', you'll note the same thing occurs.
You could set your dashboard contained to 'Standard' and the gaps will disappear, or, play with the sizing of the container on the dashboard to eliminate the white gaps.
