I'm working on reviewing a bunch of data. To best do this, I need to make 150 plots, all of which look basically the same but show data for different paramenters. To view the plots, I think the best plan is to export them to a single pdf. This way I don't have 150 windows on my screen at the same time. Is it possible to save a plot to a pdf, then loop back through the script, create a second plot, and save it to the same pdf. simple examples would be appreciated!!!
