Python streamplot the rows of x must be equal
WebNov 29, 2024 · A few features of the streamplot function are shown in this example: Varying the color along a streamline. Varying the density of streamlines. Varying the line width along a streamline. Controlling the starting points of streamlines. Streamlines skipping masked regions and NaN values. WebSep 5, 2024 · Theoretically, the integration for making the streamplot need not be done on regularly spaced 1-d x/y grids. You just need to replace dx/dy = constant by a varying function. But the streamplot code is all written assuming dx/dy are constant; I'm not wholly convinced that the streamplot code could not be simplified a fair bit and made to accept ...

Use the quiver function to plot the gradient and the contour function to plot the contours. First, create a grid of x- and y- values that are equally spaced. Use them to calculate z. Then, find the gradient of z by specifying the spacing between points.
