change the wrong figure

Today, I changed the wrong figure.

Summary:

The day before yesterday, I plotted the importance result. But there are two problems.
1. I deleted inputs one by one without using 0 to replace them.
2. The accuracy drop was not divided by original accuracy.
I fixed them and plot the following figure, which should be no problem.

Tomorrow, I will continue to look for methods to rank importance and give you the final version of the paper.
