When applying a 3 charts in 2 rows = 6 charts situation for a kind of dashboard, I would like to resize the aspect ratio accordingly by being able to handle both width and height. However, the chart gets compressed horizontally. How can I maintain the aspect ratio - is there a method to influence the corresponding height of a chart to preserve this ratio?

Thank you very much for your answer, I see.

My next step is to buy KoolReport Pro, anyway, so that I will have access to the full-blown product.
