本文介绍了在wxpython中嵌入实时更新的matplotlib图的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我是 wx python 的新手.以下是从可实时更新的文本文件中绘制实时图形的代码.任何人都可以帮我将此代码嵌入到 wx 框架中.我的项目非常需要它.
I am a newbie into wx python. The following is the code to plot live graph from a text file which can be updated live. Can anybody please help me to embed this code into a wx frame. I desperately need it for my project.
import matplotlib.pyplot as plt
import matplotlib.animation as animation
import time
fig= plt.figure()
ax1=fig.add_subplot(1,1,1)
def animate(i):
pullData= open('C:/test/e.txt','r').read()
dataArray= pullData.split('\n')
xar=[]
yar=[]
for eachLine in dataArray:
if len(eachLine)>1:
x,y= eachLine.split(',')
xar.append(int(x))
yar.append(int(y))
ax1.clear()
ax1.plot(xar,yar)
ani= animation.FuncAnimation(fig,animate, interval=1000)
plt.show()
推荐答案
这里我会给你一个例子,但你需要根据你的需要更改绘图部分:
Here I'll give you an example but you need to change the plotting part for your needs:
import wx
import numpy as np
import matplotlib.figure as mfigure
import matplotlib.animation as manim
from matplotlib.backends.backend_wxagg import FigureCanvasWxAgg
class MyFrame(wx.Frame):
def __init__(self):
super(MyFrame,self).__init__(None, wx.ID_ANY, size=(800, 600))
self.fig = mfigure.Figure()
self.ax = self.fig.add_subplot(111)
self.canv = FigureCanvasWxAgg(self, wx.ID_ANY, self.fig)
self.values = []
self.animator = manim.FuncAnimation(self.fig,self.anim, interval=1000)
def anim(self,i):
if i%10 == 0:
self.values = []
else:
self.values.append(np.random.rand())
self.ax.clear()
self.ax.set_xlim([0,10])
self.ax.set_ylim([0,1])
return self.ax.plot(np.arange(1,i%10+1),self.values,'d-')
wxa = wx.PySimpleApp()
w = MyFrame()
w.Show(True)
wxa.MainLoop()
