> I'm trying to visualize a function of 3 variables v = f(x,y,z). Edit1: Welcome! If you provide a single list or array to plot, matplotlib assumes it is a sequence of y values, and automatically generates the x values for you.Since python ranges start with 0, the default x vector has the same length as y but starts with 0. Plot the function : evolving in time. contour3 can be used for contour plot of f=(x.^2) + (y.^2);, not when f is a function of 3 variables! For a full plot of 3 independent variables and one resultant variable, you need to encode the resultant variable as marker shape (one scatter3 or plot3 call for each different marker shape), or point size (scatter3; or a lot of plot3 calls), or as color (scatter3 or patch or a lot of plot3 calls), or as transparency (patch). As we said in the introduction, the main use of scatterplots in R is to check the relation between variables.For that purpose you can add regression lines (or add curves in case of non-linear estimates) with the lines function, that allows you to customize the line width with the lwd argument or the line type with the lty argument, among other arguments. Hey, I want to plot a function of three variables. For a full plot of 3 independent variables and one resultant variable, you need to encode the resultant variable as marker shape (one scatter3 or plot3 call for each different marker shape), or point size (scatter3; or a lot of plot3 calls), or as color (scatter3 or patch or a lot of plot3 calls), or as transparency (patch). I've got a function with 3 variables: v1'= (v1*sqrt ( (1+u)^2-4*u*cos (b)^2))/ (1+u) Can you plot this function? + Manage Tags. In some cases, it may be more efficient to use Evaluate to evaluate f and g symbolically first. So I'm > wondering is there any appropriate plotting function in Octave? But generally, we pass in two vectors and a scatter plot of these points are plotted. In the R programming language, we can do that with the abline function: In other words, "stack" various plots of the same function for a few different values of z. In the 3 variable case the third variable is discretized and a contour plot of the first 2 variables is produced for each discrete value.
