The auto generated script from Graph builder has three variables (X, Y1,Y2). So i am using this auto generated script for plotting same grpah for different set of data. This is working. But whenever Y2 variable is not there in the new set of data, script is giving error. This is expected. But i would like to modify the script in such a way that it generate graph for the available variable and just ignore Y2 variable if its not availble in the given data set without giving error. Please help me to get this. Thanks!
