Hello,
I am having an issue with 2D plots in mathcad. I am unsure if there is a bug, or I am not understanding something. I am using M14 M020 14.0.2.5.
The main issue is that when using certain values for variables, my 2D plots will no longer display. See attached worksheet. With the current values, the plot showing the horizontal stresses is blank, while the vertical stresses are displayed properly. I believe that the values are still being calculated properly.
If the value for zone1 is changed to 1, then the plot displays correctly.
If the value of ELE.base is changed to 170m (with zone1=2)then it displays correctly. If ELE.base is changed to 174, then only part of the plot is displayed.
In searching for the cause/solution I have discovered something I don't understand regarding the axis values of the charts. If you look at the plots on the sheet to the right of the main plots, the function plots correctly when the maximum value on the x axis is 200, however when I change it to anything smaller, then the function does not display at all.
This is very strange behaviour which I do not understand. Can anyone explain what is going on?
