   It is suppose to advance at each mouse click. But it is odd that before the first click it is "empty". Is it possible that it has just plotted the first iteration and is not truly "empty"? 
Note that the -ksp_monitor_draw draws the plot at EACH iteration, it does not wait for all the iterations and then draw one plot at the end.
