Hi Thorsten- In the first screenshot, the area of each box is actually the same, even though some boxes have different dimensions.  As you observed, the size of your display impacts how the boxes are drawn. To adjust the box sizes via the API, please use the following steps: 1. On your Seeq installation, open the workbook that contains the Treemap and navigate to the API: 2. To get the ID of the asset that you would like to resize:        a. Navigate to GET Assets
