Mathcad contour plot11/25/2023 Vector field, 3D scatter plot and 3D bar graphs dont display either. I can, however, see contour plots of the same function. When I set up a two variable function and try to plot it, MathCAD recognizes the function and seems to plot it successfully but it doesnt display. I don't know in which version the behaviour of the 3D plots was changed and why - I was not even aware that there had been this convenient way in the good old days. Im new to these forums and I just had a quick question. If you are happy with the contour plots with wrong labels you can do that, but otherwise I found no other solution than to create those interpoation function to get what we obviously could have much easier with old Mathcad versions. Please look more closely at the axis labels/scales to see why all the work was done to create plots which equal the desired result which is seen in the pdfs.Īs already written i t is quite easy to bring the seemingly bad areas back to life simply by checking autoscaling for the axis - no need to insert a new plot. How? A new contour plot still shows just the index numbers for abscissa and ordinate, not the real frequency and range. Mathcad, a PTC Technology 1.63K subscribers Subscribe 1K views 10 months ago This video shows how to use the contour plot feature of Mathcad Prime, what is the format of the input data that. Is there a less cumbersome and elaborate way of getting that result?. In retrospective I like the bahaviour of the older version. We see that it worked in MC2K by looking at the html-version of the sheet (the second of Valerys links). In MC2000 the matrix calues are mapped to that range while in MC15 we don't see anything because the x values are out of the range 0.35. But in MC2000 it was obviously possible to cope with that by manually setting the axis scales (not the quickplot data) - in case of the sheet 50<=x<=800 and 1<=x.<=4. In MC15 there is no way to handle that if we plot a matrix. We plot a 36x36 matrix and so we only see a plot for 0<=x,y<=35, which does not reflect the true abscissa and ordinate values. I don't remember and I just had a look at the Mathcad2000 manual without being wiser, but it seems that the contourplot behaved differently in older versions. Under the advanced properties I can see the option choose colormap Q1: with the (default) rainbow map, is red the high value or low value (on the z axis) look high its the high value Q2: I believe (. Set both to autoscale and you get the same as a newly created contourplot would show. To all, I have created a contour plot and trying to control the scale and/or the colour scheme. Mathcad then linearly interpolates the values of this matrix to form level curves. Mathcad will assume that the rows and columns represent equally spaced intervals on the axes. The problem is the scaling of the x- and y-axis. To create a contour plot: Define a matrix of values to plot. The contour plot should not have this problem though, so I think the file must be corrupted in some way.
