Jan 4, 2019 · I am wondering if it is possible to get the line intensity profile from a matplotlib contour plot. Ideally I would like to hover over the contour and it give me the intensity at that point and the x and y profiles through the lines, see picture.

Sep 16, 2019 · To satisfy your requirements for #1, we can use a minimum threshold area to determine if the flake exists. For #2, once we detect the contour, we can use moments to determine the radius. Here's a simple approach. The main idea is to use a large median blur to remove the noise then adaptive threshold.

Jul 10, 2020 · In plot_surface() use alpha=0.7 and try contour() in place of contourf().

Project contour profiles onto a graph# Demonstrates displaying a 3D surface while also projecting contour 'profiles' onto the 'walls' of the graph. See Project filled contour onto a graph for the filled version.

Jun 11, 2024 · Seaborn, a Python data visualization library based on Matplotlib, provides a convenient way to create contour plots using the kdeplot() function. This article will guide you through the process of creating and customizing contour plots using Seaborn.

contour and contourf use a marching squares algorithm to compute contour locations. More information can be found in ContourPy documentation. Examples using matplotlib.pyplot.contour #

Projecting contour profiles¶ This is a comparison to the Projecting contour profiles onto a graph Matplotlib example. The get_projected_Contours method combines the multiple steps of creating the contour set, color mapping, and projecting the contour onto a plane.

Apr 21, 2020 · The matplotlib.pyplot.contour() are usually useful when Z = f(X, Y) i.e Z changes as a function of input X and Y. A contourf() is also available which allows us to draw filled contours. Syntax: matplotlib.pyplot.contour([X, Y, ] Z, [levels], **kwargs)

Mar 6, 2024 · Our goal is to animate a contour plot using Python’s Matplotlib library, transitioning smoothly between various states to better visualize and understand complex data relationships. Method 1: Using FuncAnimation for Custom Animations

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.
