Doesn't pause when I write figure to file and pipe it to gnuplot

[YjyJeff]

I want to store figure to a file and then pipe it to gnuplot to show the figure. figure.show() method works well. But when I pipe the file that I wrote to to gnuplot, it quit immediately. I tried to add a pause command in the end. However, it doesn't work.

You need to do gnuplot -p < your_file. -p makes it persist after running.
