I used the following code to export the image of the slider diagram with my GUI open. But the image never update whatever I did to modify the case and slider diagram(trip lines, etc..). It seems It doesn't make any difference whether I open the case or not, the output slider diagram image always keeps the same. I tried psse 35 and 34 both do not work. Could someone give me any idea why it happens? Thanks a lot!

psspy.case(r"""case1""")
psspy.opendiagfile(r"""slider.sld""")
psspy.exportimagefile(3,r"""figure1.png""", 100)
psspy.closediagfile()
psspy.case(r"""case2""") # case2 has extra line outage
psspy.opendiagfile(r"""slider.sld""")
psspy.exportimagefile(3,r"""figure2.png""", 100)
psspy.closediagfile()

Save your slider case changes (at case2) to a new file, slider2.sld and then use it for the second call. If you keep using "slider.sld" for both cases, the *.png would be the same.

Thank you for your solution. I tried but it still does not change. It seems it the case information does not matter for the slider diagram.

You can use the same slider diagram for different cases. The slider diagram doesn't contain any status information! There seems to be a bug in some PSSE-versions. It works correctly for me in rev 35.3.3 and 35.4.0.

The code works fine for me in rev 35.3.3. Is saved case "case2" succesfully read into PSSE?
