Dear Stata users,

I'm trying to combine multiple lqregpred (lqregpred adjs, for(v1) plotvs(v1)) graphs in Stata using -graph combine- command.

Due to the different width of the labels of individual ticks, the X axes of the graphs start in slightly different positions.

I am wondering, is there a way to force the X axes to start from the same point in graph region?

Codes:

PHP Code:

gr combine graph1a.gph graph2a.gph, cols(1) iscale(.7273) ysize(8) graphregion(margin(zero)) 

Thank you so much.
Best wishes
