Matplotlib is an amazing visualization library in Python for 2D plots of arrays. Matplotlib is a multi-platform data visualization library built on NumPy arrays and designed to work with the broader SciPy stack. It was introduced by John Hunter in the year 2002. In this article, we studied python matplotlib, matplotlib pyplot, matplotlib inline, installing matplotlib, the anatomy of a figure, backend in matplotlib, list of backend renderers, list of pyplot matplotlib functions, plotting 2D and 3D graphs, types of 2D and 3D graphs and python implementation of these functionalities.

If None, a simple autoscaling algorithm is used, based on the average vector length and the number of vectors. The arrow length unit is given by the scale_units parameter scale_units: None, or any of the units options.

I am making a quiver plot using pgfplot and I want the arrow head size to be scaled "nicely" with the length of the vector (e.g., the way Matlab quiver plot does). I've come across several solutions to similar requests, but I can't get them to work quite right. Notes. The resulting arrow is affected by the axes aspect ratio and limits. This may produce an arrow whose head is not square with its stem. To create an arrow whose head is square with its stem, use annotate() for example: from matplotlib.pyplot import * from numpy import * x = arange (10) y = x # Plot junk and then a filled region plot (x, y) # Now lets make an arrow object arr = Arrow (2, 2, 1, 1, edgecolor = 'white') # Get the subplot that we are currently working on ax = gca # Now add the arrow ax. add_patch (arr) # We should be able to make modifications to ...

I'm trying to get some "pretty" arrows for graphs and other uses in Sage. One of the problems we've been having with the FancyArrow and YAArrow is that the arrow is skewed when the aspect ratio is not 1:1 and it is scaled along with the plot. I wanted to visualize better the generated 3D quiver plot by specifiing a custom color for each arrow as follows: vector3d(x, y, z) -> rgb(x/x_max, y/y_max, z/z_max) where all values are absolute values. After browsing the doc, I came across the colors argument which is passed to LineCollection.
