Plotting second figure with matplotlib while first is still open
K here's a more precise example of what I am trying to do. I am using WXBuilder for Python as my user interface with multiple plotting functionality ie the user must be able to plot a graph based on their chosen parameters. After a graph is plotted I want the user to be able to plot a second without closing the first figure. This is for comparison purposes. Below is an oversimplified example of what I am looking to do.
import matplotlib as plt
def OnPlotClick1(self, event):
plt.plot(self.DateArray1, self.kVAArray2) plt.show()
def OnPlotClick2(self, event):
plt.plot(self.DateArray1, self.kVAArray2) plt.show()
Now I am assuming my problem is arising due plotting and showing() the graph, and therefore the program somehow is blocked from functionality until the first figure or plot window is closed.
I hope this explains my problem better.
您也可以在同一幅图中绘制两个或两个以上的绘图仪
import matplotlib.pyplot as plt
def my_plotter(ax, data1, data2, param_dict):
out = ax.plot(data1, data2, **param_dict)
return out
fig, (ax1, ax2) = plt.subplots(1, 2)
#here you put your data
data1=[0,1,2,3,8]
data2=[0,1,2,3,8]
data3=[0,1,2,3,8]
data4=[0,1,2,3,8]
my_plotter(ax1, data1, data2, {'marker':'x'})
my_plotter(ax2, data3, data4, {'marker':'o'})
plt.show()
You should not block show. Use:
import matplotlib.pylab as plt
plt.plot([1,2,3]) # first plot
plt.show(block=False) # do not block
plt.plot([11,21,31]) # second plot
Each window is in matplotlib parlance, a new figure. You can call plt.subplots twice to create two figures:
import numpy as np
import matplotlib.pyplot as plt
x = np.linspace(0, 10, 1000)
y1 = np.sin(x)*np.exp(-x/5.0)
y2 = np.sin(x**2)*x
fig1, ax1 = plt.subplots()
ax1.plot(x, y1)
fig2, ax2 = plt.subplots()
ax2.plot(x, y2)
plt.show()
Note that plt.show() starts a GUI event loop and so generally it should only be called once per script.
