On a dataset, by default the sorting is done on the metric and not on the property.
In order to assign the same color to each element of the chosen property on your charts, and this for different boxes, we advise you to go to the edition mode of your dashboard, in order to modify the charts of your dashboards.
For each of your charts, modify your dataset in order to change the sorting order; you must apply an ascending or descending order (alphabetical or not) on the concerned property. If you want the color of the metrics to be the same for each dimension, you will have to choose the same sorting on each dataset.
