"Stata has stopped working"-error when using kdensity in twoway graph

[Morten Nielsen]

I am new to Stata and have recently run into problems with the graph twoway and kdensity commands in Stata 13.1.

kdensity x if x < 1000

kdensity y if y < 1000

both produce the desired graphical output. But when running

twoway (kdensity x if x < 1000) (kdensity y if y < 1000)

I get a dialog box with the error message "Stata has stopped working" and Stata shuts down.


Has anyone experienced something similar or have a clue as to what I am missing? I am able to produce e.g. twoway scatter plots without Stata issuing the same error

Morten:
welcome to the list.
I cannot replicate your problem, as the following:

. set obs 1000
obs was 0, now 1000

. g x=10000*runiform()

. g y=10000*runiform()

. twoway (kdensity x if x < 1000) (kdensity y if y < 1000)

works for me (i.e., produces graphs) under both Stata 13.1/SE and Stata 14.2/SE.

Are you sure that your version of Stata 13.1 is fully updated?

[Morten Nielsen]

Thanks.

Your example works for me as well, so I guess the problem is related to the data I am using. I will investigate this further.
As I am working on a external server I cannot update my current version of Stata. But it seems the problem is related to something else.

Best, Morten

The next step might be to ask the Stata support folks. They are extremely helpful. If this is happening, it might indicate a bug.
