Plotting line graph over scatter graph

I am aware of how to plot a line graph on top of scatter plot of the same data but is there a way to bring the line graph forward so it sits on top of the markers rather than behind?

Example code:

import numpy as np

x=np.array([1,2,3,4,5])
y=np.array([1,2,3,4,5])

plt.errorbar(x,y,xerr=0.1,yerr=0.1, fmt="x",markersize=5, color = "orange")
plt.plot(x,y)

This code outputs a scatter graph with a line graph behind it. When you increase the number of data points it becomes harder to see the line behind them all. Other than decreasing the marker size can I bring the line on top of all the points?

Solution

  • I think you are intending to draw things at different levels of z-order on the screen. This is done like such:

    plt.plot(x,y, zorder=10)

    Note 10 is arbitrarily large and this will likely plot on top of your legend too, so you may need to adjust it!
