        This tool will generate a scatterplot representing data from two groups/conditions. 

        The input data should be in tabular format and the user can determine which groups (columns) to plot.

        Multiple groups can be plotted on the same or multiple plots by providing a column with a group identifier under "Advanced - plotting multiple groups".

        Feel free to explore the (many) advanced options to customize your plot. Galaxy makes this type optimization easy for the user!  

        The ouput is a pdf file with your scatterplot. The dimensions of this file can be modified under "Advanced - output dimensions"
