Extend width of card

I am becoming crazy in here … 2 hours that I am trying to extend the width of this history-graph card without it also extends to the bottom.
This is for a tablet, I do not want to scroll to I am limited in height with 715 pixels (I have made a “custom:grid-layout” with 11 x 65 pixels.
I have this history card in the first column, You see it goes till the 715 pixels, but I would like to extend the width … without success …
If I increase the first column, then it affectively increases the width, but also the height …
If I set r2-1 on the second column, that doesn’t work.
I have also tried with card-mod but there no success neither.
What is the solution in here ?

I am also pasting my code in case you can edit it / test it to get the desired purpose :
