Matplotlib Markers

This lesson is part of Python · All levels

Summary

A marker is a small symbol at each data point in a line graph, such as a circle 'o', a star '*', or a box 's'. The size of the marker is set by the parameter ms (markersize), the color of the contents by mfc, and the color of the edge line by mec. Marker also becomes a key element in scatter graphs, where each symbol represents one observation. Marker adjustments help to keep data dots visible, especially when the lines are thin or the data is very large.
