To reproduce any of these, use the following script with trivial modifications. I could do many more, but that will probably enough for this blog :-) Below, I’ve plotted the phase (actually the sine of the phase, to make it continuous) of a Jacobi theta function θ 3(1+4j/3,q) (restricted to |q| < 0.8, because it gets extremely messy for larger |q|): Since the pure wireframe plot is much faster, I think I prefer it for now.įor complex functions, it’d also be nice with a color function separate from the geometry function - then you could plot the phase as color in the same picture.Ĭolor helps for visualizing complicated structure, especially for phase plots. This doesn’t seem possible with matplotlib because the surface plot doesn’t do smoothing (even with a stride selected) overlaying a wireframe works decently, but the wireframe doesn’t render with occlusion and this looks bad for some functions. I’d like to be able to do a surface plot with a widely spaced wireframe mesh to pronounce the geometry, and smooth colored surface between the meshes. Using the Riemann zeta function again, a surface plot looks as follows: Riemann zeta function in the critical strip: Imaginary part of Lambert W function, 0th branch: Principal-branch logarithmic gamma function: ![]() Until I’ve figured out the details, I’ll share a couple of test plots.Ĭoulomb wave function of a complex argument, F(6,4,z): There will probably be a 3D plot function in a future version of mpmath (or two functions for two-variable real, and complex functions), similar in style to the existing matplotlib wrappers plot and cplot. A big advantage of 3D plots over 2D color plots is that far fewer evaluation points are required for a good high-resolution image, and this helps when visualizing the slower functions in mpmath. These plots are informative, but sometimes a 3D plot (typically of the function’s absolute value) gives a much better view. I’ve shown a lot of color plots of complex functions on this blog to demonstrate complex functions in mpmath. Hooray! matplotlib 0.99 is out and it has 3D plotting, finally! Vivid photo inks produce bright, high-detail photographic quality images on the following substrates and may be used outdoors with limited weather and sun exposure: As of July 15, 2021, IT Services has retired poster printing (CPLOT) and computer lab document / blog / 3D visualization of complex functions with matplotlib Document printing is now managed by Imprint's 20+ Wepa printers, and their on-campus poster printing service. ![]() cplot: Conditional predicted value and average marginal effect plots for models Description Draw one or more conditional effects plots reflecting predictions or marginal effects from a model, conditional on a covariate.Backlit film for photo-quality images, used in indoor or outdoor sealed boxes.Photo papers in either satin or gloss finish make photos pop.50-pound bond is a heavyweight, bright white paper and an excellent choice for indoor posters and signs.Imprints also supports student, faculty, and staff printing from personal computers and smartphones, all using TritonCash, Student. Moreover, his standard helmet is of neon green color, which is also the theme for his eSports organization Quadrant. Cotton canvas is an ideal choice for art reproduction. cplot uses OKLAB, a perceptually uniform color space for the argument colors.Scrim vinyl is a waterproof material suitable for large, hanging banners for outdoor use.Polypropylene is an excellent and economical choice for one-time indoor or outdoor presentations.Currently methods exist for lm, glm, loess class models. Tyvek is a durable medium that can be used indoors or outdoors. This avoids streaks of colors occurring with other color spaces, e.g., HSL. As of July 15, 2021, IT Services has retired poster printing (CPLOT) and computer lab document printing. The contour abs(z) 1 is emphasized, other abs contours are at 2, 4, 8, etc. ![]() ETS - Print Queue Manager Cplot has been retired. ![]() This makes it easy to tell the absolte value precisely. Document printing is now managed by Imprints 20+ Wepa printers, and their on-campus poster printing service.
