Hi Caca Zhang
It is possible that you are not displaying the graph output before trying to export it. This problem is particularly common when exporting into PNG format.
So, the main question: can you see the graph you are trying to export before you try to export it?

On Fernando's point, make sure you've specified the "name" option

sysuse auto, clear
sc price weight, name(scatter, replace)

such that Stata names it that

Sorry, I only saw your reply now, thank you very much for your help.
For Fernando's question, I can't see the chart;
For Jared's suggestion, I will try;
After restarting the computer today, it can be used. I am also in confusion. Thank you for your enthusiastic help.
