Plotting Issue

Plotting Issue

I have what is probably a simple plotting issue. It occurs at the bottom of the attached worksheet. I am comparing four outputs from Odesolve and Radau: velocity, stress, porosity and pore pressure. When I plot the velocity and stress together there is no problem (I know there are some differences in the peaks, but I understand why this is happening and it is not the issue). For the porosity and pore pressure, the outputs look ok if I put them on separate plots, but if I put them on the same plot, the output from the second quantity on the plot (from Odesolve) does not seem to plot correctly.

Hi John, thanks for saving it in Mathcad 11 format. Though it's no longer necessary to save as a .ZIP file. That forum problem was corrected some time ago.

 

To your plotting problem:

I see no definition of t. I'd expect it to be defined as a range, at least.

Now you're using the quickplot feature, which means Mathcad gets to choose the values of t. While that goes well in many cases, here it may cause interference with the values in the first column of S4...

 

Success!
Luc

Thanks Luc. That was the solution. Defining t explicitly eliminated the problem.
