I am trying to build a gui app for graph plotting. I used multiple files to read and plot as a slideshow. For that first set of data is read and plot then after a time interval it should plot next set of data and so on. I also have play ,pause, forward, backward for the slideshow for plot. Data from the file should be plotted as a slideshow if play button is clicked. For pause button, it should pause the slideshow. Forward and backward button for loop to plot forward play and backward play.
