matplotlib extension functions to plot trajectories

3D trajectory with equal size axes

To generate a quick 3D trajectory plot with equal-axis is a one-liner:

import matplotlib.pyplot as plt
import trajplotlib

# compute/load data for xs, ys, zs

# create plot
fig, ax = trajplotlib.quickplot3(xs, ys, zs, radius=184.0)
plt.show()

In the above, xs, ys, and zs are arrays of the trajectory coordinates, and radius is an optional value for plotting a sphere of radius radius.

This generates the following:

The above function returns ax, which is an Axes3DSubplot object. As such, the plot may be modified or more elements may be appended just as one would do with regular matplotlib:

ax.set_xlabel('x, km')
ax.set_ylabel('y, km')
ax.set_zlabel('z, km')
ax.set_title("My trajectory")
