You can use matplotlib.patches.FancyArrowPatch to draw a two-headed arrow. This class allows to specify arrowstyle : import matplotlib.patches as patches p1 = patches.FancyArrowPatch((0, 0), (1, 1), arrowstyle='<->', mutation_scale=20) p2 = patches.FancyArrowPatch((1, 0), (0, 1), arrowstyle='<|-|>', mutation_scale=20)

Detailed examples of Dumbbell Plots including changing color, size, log axes, and more in Python.

matplotlib.pyplot.arrow# matplotlib.pyplot. arrow (x, y, dx, dy, ** kwargs) [source] # [Discouraged] Add an arrow to the Axes. This draws an arrow from (x, y) to (x+dx, y+dy).

Is there an automatic way to generate all the arrows, given I have the vectors x, y, dx, dy? You can use a quiver plot (example here). Why not a for loop?

Oct 3, 2021 · In this tutorial I will be walking you through the process of creating dumbbell charts in Python using data analysis and plotting libraries: Pandas, Numpy and Matplotlib.

Arrows are often used to annotate plots. This tutorial shows how to plot arrows that behave differently when the data limits on a plot are changed. In general, points on a plot can either be fixed in "data space" or "display space".

In short this is used to plot arrows along your lines in matplotlib. The code is shown below. It can still be improved by adding the possibility of having different arrowheads.

Apr 7, 2025 · One of its useful functions is arrow(), which lets you add arrows to your plots to highlight or point out specific data points or trends. This article explains how to use the arrow() function, its syntax and how to customize arrows using various parameters.
