如何在python图中连接点？

Question

Wanted to connect points in matplotlib plot.below is the sample code. each element in list has timestamp and argv. Please educate.Code below plots correctly but do not connect points between different elements of list even if I have mentioned 'rs-'.

for a in list:
      plt.plot(a.time,a.argv,'rs-')

Answer 1

If you want your points connected, you need to plot them all in one call. Create a list of the points you want to plot, then call plt.plot

points = [(a.time, a.argv) for a in l]
plt.plot(points, "rs-")
