Then I want to add my colorbar beneath this figure but what happens is starting from the 2nd file, it only plots the frame (from set_viewport command) and plots everythin else inside this frame. How can I fix this? I use /advance and /noerase keywords in the map projection and contour routines but it gets stuck in this viewport. When i just do set_viewport,device. I can see the map
