目标是在图表上输出实时数据,并能够更改其尺寸。我尝试使用从here获取的默认matplotlib示例。我已经改变了一点:
import numpy as np
import matplotlib.pyplot as plt
import matplotlib.animation as animation
def data_gen():
t = data_gen.t
cnt = 0
while cnt < 10000:
cnt+=1
t += 0.05
yield t, np.sin(2*np.pi*t) * np.exp(-t/40.)
data_gen.t = 0
fig, ax = plt.subplots()
line, = ax.plot([], [], lw=2)
ax.set_ylim(-1.1, 1.1)
ax.set_xlim(0, 5)
ax.grid()
xdata, ydata = [], []
def run(data):
t,y = data
xdata.append(t)
ydata.append(y)
xmin, xmax = ax.get_xlim()
if t >= xmax:
ax.set_xlim(xmin, 2*xmax)
ax.figure.canvas.draw()
line.set_data(xdata, ydata)
return line,
ani = animation.FuncAnimation(fig,run,data_gen,blit=True,interval=10,repeat=False)
plt.show()
在窗口尺寸发生变化之前,一切都很好。 Matplotlib通过整个图形绘制线到第一点,然后将另一条线绘制到它想象的位置。最后它看起来像this。所以这个数字搞砸了,我不知道该如何处理它。
我使用的是Ubuntu 15.04,python 2.7.9,matplotlib 1.4.3。在Windows 7和8.1上也是如此。
答案 0 :(得分:0)
要完全关闭此问题,因为即使在matplotlib 2.0.0中也会出现此问题,我将自己回答这个问题。正如 @BrenBarn 指出的那样,我只需要<Style TargetType="Navigation:HtNavigationMenuCategoryItem">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="Navigation:HtNavigationMenuCategoryItem">
<Grid Margin="10,10,10,0">
<StackPanel Orientation="Vertical">
<ItemsControl ItemsSource="{Binding RelativeSource={RelativeSource TemplatedParent}, Path=CategoryItems}">
<ItemsControl.ItemContainerStyle>
<Style TargetType="Navigation:HtNavigationMenuCategoryItem">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="Navigation:HtNavigationMenuCategoryItem">
<Controls:FooControl Text="test" Foreground="Yellow"></TextBlock>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
</ItemsControl.ItemContainerStyle>
</ItemsControl>
</StackPanel>
</Grid>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
。
