Scale chart (sm 9.3x)

I neeed to scale the chart.

I put on the screen 6 charts on the screen (they are all in the same dashboard). 

They all displayed in 1 row and more than half of the screen is empty.

It would be ideal to show 3 graphs in two rows on the screen (in full screen).

Is it possible to control the scale and location of charts on the screen ?
