> > Sungbok: I tried your example on Stata 11 MP on Mac OSX 10.7 with 32G of mem & again on Stata 11SE on Windows Server 2003 with 10G of mem but I could not reproduce the problem. The latter system got a bit slower when generating more than about 30 graphs, but it did not freeze. Since you stated that you've found that there is some limit in terms of the number of graphs that will open, based on memory allocation, I think your best solution would be to not allow Stata to open all those graph windows/tabs at the same time. To do so, I would put commands in your loop to save the graphs, export them to your favorite format that can be opened in an external program (e.g., .pdf, .eps, etc.), and then close the graph window before generating the next graph in the loop. I don't know what the benefit of having all 40 graphs open at the same time would be unless you wanted to compare them in some kind of -graph combine- scenario--if you simply want to tab through them in fullscreen, you can do that in another program. I've modified your do-file with these changes (closing/saving the graph windows & creating a combined graph window at the end), you can then go and open your newly created graphs in some external graphic-viewing program: ********* clear all set more off set mem 32g set graphics on set obs 20000 gen x = runiform() gen y = rnormal() local in = 40 g str5 graph_name = "" //<-- for later use with -graph combine- forvalues i=1(1)`in'{ twoway(scatter x y)(line y x), name(toy`i') graph save toy`i'.gph, replace graph export gr`i'.eps, as(eps) replace name(toy`i') window manage close graph toy`i' replace graph_name = "toy`i'" in `i' } //for a combined graph// levelsof graph_name, local(gn) graph combine `gn' graph save all_toy.gph, replace graph export all_top.eps, as(eps) replace drop graph_name ********* **note** I turned off tabbed graphics windows preference in the Windows OS version of Stata (it's not an option in the Mac OSX version of Stata)...I didn't try this with the tabbed graphics window preference on. ~ Eric __ Eric A.

I also saved all graphs generated by loop and selected graphs for combining with the commands of `graph use' and `graph store' by loop. But, sometimes, I press a button for maximizing the window size without a caution. This freezing problem occurs even when pressing 'graph edit'. My STATA 11 is 64-bit MP version on Windows Vista. I allocate 20g for memory partly because my data size is huge and partly because the installed memory is 32g. I also simulated a simple case. I found that it may depend on the number of graphs, the allocated memory size and the option of graphic window. Actually, it does not matter with the capacity of processing graphs in STATA. I sometimes hope to save the codes even when encountering this freezing. Thanks again, and I will communicate with STATA.com later. > > If anyone is wondering this problem, try it. > > * open stata --> edit --> preferences --> graph preferences --> check "Create multiple graphs as tabs in a single window" > > clear all > set more off > set mem 10g /* <- change as you have */ > > set graphics on > > set obs 2000 > gen x = runiform() > gen y = rnormal() > > local in = 40 /* <- change as you want */ > forvalues i=1(1)`in'{ > > twoway(scatter x y)(line y x), name(toy`i') > > } > > > > > Sungbok Lee > > 4th Year Graduate > Department of Economics > TAMU > javanfish@tamu.edu > 422-1088 > http://www.searchatall.com > > -------------------------------------------------- > From: "Clyde Schechter" <clyde.schechter@einstein.yu.edu> > Sent: Friday, December 04, 2009 9:31 AM > To: <statalist@hsphsun2.harvard.edu> > Subject: Re: st: Still Thinking or Resisting > >> FWIW, I had a similar problem several months back.
