Adding uniform y-axis scale to graphs while combining them

[Dhiroj Prasad Koirala]

Hi all,
I have been trying to make two different kdensity plots using command below:

kdensity tsolar, addplot((kdensity bsolar)) legend(order(1 "Census Tract" 2 "Census Block") pos(12)) ytitle(Density) xtitle(Number of census tracts (blocks)) name(t_b_solar, replace)
kdensity tsolar, addplot((kdensity bsolar)) legend(order(1 "Census Tract" 2 "Census Block") pos(12)) ytitle(Density) xtitle(Number of census tracts (blocks)) name(t_b_sample_solar, replace)

Then when I combine them:

graph combine t_b_solar t_b_sample_solar

I see those graphs have different y scale. I tried different ways to make these graphs to have a same y-axis range (0 - 0.3), but nothing worked. Could someone help?

Hi Dhiroi,

Did you try:

graph combine t_b_solar t_b_sample_solar, ycommon

?

I may be missing something but what is different about those commands? Are you changing the data in between?
