Trellis bar chart customization - DS 1.4

Hi,

I need to present trellis chart (split by months as shown on picture below).

Do you know wheter it is possible to control the width of each bar chart in the trellis? I would like to shrink each small chart so I would display all 12 months in one screen.

I tried to seach for any configuration inside DS 1.4 but there is not much options.

Best Regards,

Pawel
