Markers are used in Matplotlib plots to mark the points on a line which refers to a datapoint. All the possible marker styles in Matplotlib are listed here.
However, it is difficult to pick a marker just by looking at its character or its label. I generated the above image as a visual reference to pick markers. It was generated by using this piece of code:
#!/usr/bin/env python
import matplotlib.pyplot as pyplot
= {
mark_dict ".":"point",
",":"pixel",
"o":"circle",
"v":"triangle_down",
"^":"triangle_up",
"<":"triangle_left",
">":"triangle_right",
"1":"tri_down",
"2":"tri_up",
"3":"tri_left",
"4":"tri_right",
"8":"octagon",
"s":"square",
"p":"pentagon",
"*":"star",
"h":"hexagon1",
"H":"hexagon2",
"+":"plus",
"D":"diamond",
"d":"thin_diamond",
"|":"vline",
"_":"hline"
}
def line_plot():
= [1, 10, 30, 70]
x_list = [10, 20, 30, 40]
y_list
pyplot.clf()for mark in mark_dict:
= [y_val + 10 for y_val in y_list]
y_list =mark_dict[mark], marker=mark)
pyplot.plot(x_list, y_list, label
="best", prop={'size':11})
pyplot.legend(loc"markers.png")
pyplot.savefig(
def main():
line_plot()
if "__main__" == __name__:
main()
Tried with: Matplotlib 1.3.0 and Ubuntu 12.04 LTS
