We have seen how to plot temperature/ species as functions of time (History Plots) for a particular node in the Tutorials and the example covered in class thus far. However, sometime you may need to plot the temperature/ species history for more than one node in the same window to compare the results for different nodes. The following steps outline the procedure for doing it. (Do the following steps after running your simulation in PreSTO)
1) Accept the file: FIPOST >> Accept. A new set of menu list comes up (see Figure).
2) Click on Plot. We are plotting the species history for different nodes for the problem done in class on Drug Delivery. The Plot window opens up.
3) In the Plot window, click on HISTORY. HISTORY Command window opens up.
4) Select Species from the drop down list below DEGREE OF FREEDOM. Left click on the slider and move it to 1 while holding the mouse.
5) Click on Accept. A new tab comes up on the top right hand side of the screen which says DATA NEEDED. 
6) Click on the text input field next to INPUT on the lower left side of the screen and type 10 200 50 and press Enter. The three numbers that are input represent ND1, ND2 and NGEN. ND1 is the first node number, ND2 is the last node and NGEN is the increment. In this case, the species history will be plotted for the nodes 10, 60 (=10+50), 110 (=10+2*50) and 160 ((=10+3*50).
7) Click on the text field again and type 0 and the press enter. 0 is entered to terminate the input command for the history plot.
You should see the species history plots for the nodes 10, 60, 110 and 160 in the Graphics window as shown below (These plots are for the problem covered in class on drug delivery)
