Adaptive Design: Column chart width expand in drill-down

[gomeri]

Hello, everyone,
when I insert a column chart and use a dimension and a measure the distribution of the columns (dimension values) is horizontal (in width) and if there are a lot of columns (dimension values) the chart spreads well horizontally.

However, when there are only two columns (values of a dimension) I see that the chart does not fit in width. Is there an alternative way to display the data described above in a better form of visualization?

Thank you
