[Matplotlib-users] using the matplotlib backend with another Tk window.

[Hiro T. <hi...@as...>]

Hi,

 

I am trying to change my plots using another tk window I made, but it does
not work well.

I am wondering if someone could help me.

 

Here is an example to try to change the X axis of the plot using scale bars
on another

Tk window. But once I run the program, the figure window for matplotlib gets
darker several

second later, and I cannot use pan/zoom buttons etc.

from pylab import *

from Tkinter import *

 

class TkWindow(Frame):

  def init(self):

    self.vmin= IntVar()

    self.vmax= IntVar()

    self.vmin.set(0)

    self.vmax.set(10)

 

    l2=Frame(self)

    scale_vmin=Scale(l2,label='x(min)',variable=self.vmin,

                to=20,from_=-20,length=200,tickinterval=10,

                     orient=HORIZONTAL)

    scale_vmax=Scale(l2,label='x(max)',variable=self.vmax,

                to=20,from_=-20,length=200,tickinterval=10,

                     orient=HORIZONTAL)

    scale_vmin.pack(side=LEFT,padx=5)

    scale_vmax.pack(side=LEFT,padx=5)

    scale_vmin.config(command=self.exec_scales)

    scale_vmax.config(command=self.exec_scales)

    l2.pack(fill=X)

 

  def exec_scales(self,event):

    vmin=self.vmin.get()

    vmax=self.vmax.get()

    ax.set_xlim(vmin,vmax)

    draw()

 

  def __init__(self,ax,master=None):

    self.ax=ax

 

    Frame.__init__(self,master)

    self.init()

    self.pack()

 

### Begin ###

 

ax=subplot(111)

plot(arange(0,10))

tkw=TkWindow(ax)

 

show()

tkw.mainloop()

Thanks a lot for your attention!!
