Question

Troubleshooting with several 3d plots in one graph

Hi

I have 3 surface plots and one vector that I would like to plot in the same coordinate system.
The situation is the following (axis scales are predefined and fixed):

1) Each plot by itself works fine

2) If I plot one surface plot and the vector the vector is reduced to a dot

3) If I plot a second surface plot to an existing one mathcad does the "divide by zero"-error.

Any help or work around appreciated! (I run Mathcad 14 on 64-bit Windows 7)

Please post a worksheet showing the problem.

ok, its a bit messy but its the plot all the way to the bottom

thanks so much for your effort!

Could you add the other two plots you are having trouble with. I have no way of guessing what you typed into the graph placeholder for those.

If the vector is so short, then scale or otherwise mesh the surface plot on the same scale as the vector.

The principle of scaling a vector [pole] and the surface plot.

No matter the type of surfaces and vector, just plot what

you have, if plottable ... You may have to do some re-work.

Sorry for the inconveniences - new file attached with all the single plots i want to make at the bottom

Scaling solved the Vector problem (might still be incorrect in the attached file but I solved it now)

However, two surface plots in one graph is still a problem.

Maybe the error is the following: when trying to plot in a defualt coordinate system Mathcad always does the divie by zero error which is correct regarding the functions i attempt to plot. I then have to adapt the quickplot data to make it work. But when adding a second surface plot to an existing one it wont let me access the quickplot data anymore for that plot but automatically does the divide by zero error. I can still access quickplot data for plot one.

Thanks for your time!
