I am using matplotlib to plot multiple curves (time series) in one plot. To do this, I use a for
loop as seen below.
%matplotlib
for i in range(0, len(force)):
plt.plot(distance, (force[i]), alpha=0.1)
plt.xlabel('Distance [mm]', fontsize=12)
plt.ylabel('Force [N]', fontsize=12)
Unfortunately, with the number of curves (approx. 70) that I have, the plot would be unreadable if I labeled each curve. Does anyone know of a way to create labels that only appear when the cursor hovers in the vicinity of that curve (timeseries)?
I looked on the example from this post, but have no clue how to adapt it to my issue:
Possible to make labels appear when hovering over a point in matplotlib?
You could use mplcursors. Each curve can have a unique label, which is shown by default.
from matplotlib import pyplot as plt
import mplcursors
import numpy as np
force = np.random.randn(70, 100).cumsum(axis=1)
force -= force.mean(axis=1, keepdims=True)
plt.figure(figsize=(12, 5))
for i in range(len(force)):
plt.plot(force[i], alpha=0.2, label=f'force[{i}]')
plt.margins(x=0.01)
cursor = mplcursors.cursor(hover=True)
plt.show()
If you're working with a Jupyter notebook, you might need %matplotlib nbagg
or %matplotlib qt
instead of %matplotlib inline
to enable interactivity.
