I think the settings of the plot and the PF do not need to update at each iteration, these operations are time-consuming.

So, I add two properties for PROBLEM, fastdraw and display, where fastdraw is 0 or 1, and display is a string of the current display item, and add the PROBLEM as a new argument for Draw()

PROBLEM.fastdraw=0 when the PROBLEM objective is created. The plot will be updated by the usual method if PROBLEM.fastdraw=0.

When the PROBLEM.fastdraw=1, the Draw() will only update the plot of solutions, the settings of the plots and the PF will not be updated.

The purpose of PROBLEM.display is to detect the change in the display item, it will be updated after the plot has been drawn at each iteration. At each iteration before the Draw() running, If the current display item is not the same as PROBLEM.display, that means that the display item has been changed, then the PROBLEM.fastdraw will be set to 0. After the plot has been drawn, the PROBLEM.fastdraw will be set to 1. In the following iteration, if the display item is not changed, only the plot of solutions will be updated.

I have debugged these codes, and it's significantly faster than the original. If these codes have any bugs, please let me know, thank you.
