20 maj 2019 · 5. i'm looking for the best way to create a contour plot using a numpy meshgrid. I have excel data in columns simplyfied looking like this: The x and y values define a 2d plane with the length (x-Axis) of 7 values and depth (y-Axis) of 2 values.
Contour plots in Python with matplotlib: Easy as X-Y-Z. Feb 24, 2020 • A quick tutorial on generating great-looking contour plots quickly using Python/matplotlib.
Meshgrid() The function meshgrid() takes two vectors x and y that contain the location of the grid points and generates matrices X and Y that are used by all 2D Matlab plotting functions, in particular contour()/contourf() and surf(). f = @(x,y) x.*y; g = @(x,y) y; Nx = 4; Ny = 3; N = Nx*Ny N = 12 x = linspace(0,1,Nx) x = 1×4 0 0.3333 0.6667 1 ...
A contour plot can be created with the plt.contour function. It takes three arguments: a grid of x values, a grid of y values, and a grid of z values. The x and y values represent positions on the plot, and the z values will be represented by the contour levels.
Contour Plots¶ Contour plots can be created with Matplotlib. In Civil Engineering a contour plot could show the topology of a building sight. In Mechanical Engineering a contour plot could show the stress gradient across part surface.
Comparison of a contour plot of irregularly spaced data interpolated on a regular grid versus a tricontour plot for an unstructured triangular grid. Since contour and contourf expect the data to live on a regular grid, plotting a contour plot of irregularly spaced data requires different methods.
meshc(X,Y,Z) creates a mesh plot with a contour plot underneath. A mesh plot is a three-dimensional surface that has solid edge colors and no face colors. The function plots the values in matrix Z as heights above a grid in the x-y plane defined by X and Y.
