net_graph "1"
net_graphheight "840" // Changes height, how high on the screen it is.
net_graphinsetbottom "130" // Adds additional margin which is added to the height. You could also set this to 0 and increase the height.
net_graphinsetleft "80" // Adds margin to the left
net_graphinsetright "0"
net_graphinsettop "0"
Happy tweaking.

Also use net_graphproportionalfont "0" to make it small.
