Screen cell sizing

[zabbixhack]

I am creating screens with graphs. I have added two graphs of the same size to two cells. There are two things wrong already:
1. The graphs are different sizes even though they are configured with the same dimesions.
2. The space around the graphs is excessive. I need (like most people (I would think) for the cell to size to the object inside it. At this rate, the screen will be huge, with wasted space.

What's the trick here to get the graphs the same size in the screen and get the cell to collapse around the object?

Thanks

Sorry. This is version 1.8.11

Content matters

1. Solved, sorta
So I see that the content is a part of the sizing. I had no Y axis on the right on one graph, so I had to make it larger to compensate. The same goes for # of items. I have one more on one and it makes it taller.
I can work with that I suppose. It would be nice to auto-scale the text so that it's not cut off when the graph is set for a smaller dimension.

2.
The border space around the graph is now my only real issue. I don't want all that wasted space.
