python - Export matplotlib pdf with text not as path from tkinter -

i have simple gui plots figure this:

def display_graph(self,f1):       self.canvas = figurecanvastkagg(f1, self)      self.canvas.show()      self.canvas.get_tk_widget().place(anchor = n ,x = 200 ,y= 150)      self.get_all_figures()      self.canvas._tkcanvas.place(anchor = n ,x = 675 ,y= 325)      self.toolbar_frame = frame(self)      toolbar = navigationtoolbar2tkagg(self.canvas, self.toolbar_frame)      self.toolbar_frame.place(anchor = n ,x = 540 ,y= 933) 

there text xlabel, ylabel , user should able export in pdf format. work figure great if displayed text text object in example illustrator, recognized path. (no font information). have changed pyl.rcparams['pdf.fonttype'] = 42 work when plot directly console. there trick make happen gui using canvas?

to save image use toolbar , function (depending on user clicks)

def save_all(figures,save_path_name,curr = 'all'):  try:       pp = pdfpages(save_path_name)        if curr == 'last':            pp.savefig(figures[-1])          else:            in figures:                 pp.savefig(i)       pp.close()  except (oserror, ioerror) e:           messagebox.showinfo('error ...',e)           return  

this trick. updating everytime before plotting graph. not able make work, when changed in rc file. strange maybe overseeing something.

def display_graph(self,f1):  plt.rcparams['pdf.fonttype'] = 42  matplotlib.rcparams['pdf.fonttype'] = 42   self.canvas = figurecanvastkagg(f1, self)  self.canvas.show()  self.canvas.get_tk_widget().place(anchor = n ,x = 200 ,y= 150)  self.get_all_figures()  self.canvas._tkcanvas.place(anchor = n ,x = 675 ,y= 325)  self.toolbar_frame = frame(self)  toolbar = navigationtoolbar2tkagg(self.canvas, self.toolbar_frame)  self.toolbar_frame.place(anchor = n ,x = 540 ,y= 933)
