Opening Graph Files

[Paulo Regis]

Hello,

I have created a graph using the following line (where X, Y and Z are the three variables for the contour plot):

twoway contour Z X Y , level(10) xlabel(0(200)1400) ylabel(0(200)1400) xscale(reverse)
graph save Graph "D:\2016-07-15_Space2007-2011.gph", replace

It takes around 3 days to do the plot because of the large combination of X and Y. Because it takes so long ot do the graph, I have saved it. However, it is taking a really long time to open the graph file now (12 hs and couting). Is there a gain in saving the file or should I run the command again?

Also, is there another way to open the file? I am not sure files with extension .gph can be opened with other software.

thank you for your help

Paulo

Just in case the issue come up, X=1,2,...,1400 and Y=1,2,...,1400 so that is a really long combination of values (1400*1400=1960000)
