Updating Matplotlib Plots Efficiently
To update plots in Matplotlib while avoiding repeated plotting, consider the following options:
1. Clearing and Replotting with Clear Method
Call graph1.clear() and graph2.clear() before redrawing the plot. This ensures a clean slate, but can be slow.
2. Updating Data of Plot Objects
Update the data of existing plot objects instead of replotting entirely. This is faster, but requires the data shape to remain constant. Manual axis limit adjustment may be necessary.
To demonstrate the second option:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 |
|
This method efficiently updates the plot data in real-time without redrawing the entire plot.
