Embedding, Drawing, Curser in Tkinter

stefanschubi · May 11, 2017, 5:17am

Hello to everyone.

I develop a GUI and i want to embedd Matplotlib in a Tkinter Canvas. Theres
is no problem until here. But i want to draw the lines and have a curser
line in the diagram. In the code below i embedd the canvas in the
INIT-Function.

class BOStrab_Fahrzeugeinschraenkung:
  def __init__(self, top=None):
            ......
    self.ya = np.array(ddd)
    self.yb = np.array(ddd)
    self.z = np.array(ddd)

    self.canvasframe11 = Frame(self.TPanedwindow4_f2)
    self.canvasframe11.place(x=0, y=0, relwidth=1.0, relheight=0.95,
bordermode=INSIDE)
    self.canvasframe12 = Frame(self.TPanedwindow4_f2)
    self.canvasframe12.place(x=0, rely=0.95, relwidth=1.0, bordermode=INSIDE)

    global ax1
    self.fig1 = Figure (figsize=(5,4), dpi=100)

    self.ax1 = self.fig1.add_subplot(111) #f?r 2d-Plot
    self.ax1.set_title('Definition der LRUGL')
    self.ax1.set_xlabel('Breite y [mm]')
    self.ax1.set_ylabel('Hoehe z [mm]')

    self.ax1.axis([-2000,2000,0, 5000])
    self.ax1.grid(True)
    self.ax1.plot(self.ya,self.z, color='red', linestyle='--', marker='')
    self.ax1.plot(self.yb,self.z, color='red', linestyle='--', marker='')

    self.canvas1 = FigureCanvasTkAgg(self.fig1,self.canvasframe11)
    toolbar1 = NavigationToolbar2TkAgg(self.canvas1, self.canvasframe12)

self.canvas1.get_tk_widget().pack(fill=BOTH, expand=TRUE, pady=2, padx=2,
anchor="n")

In several examples i saw the drawing in def's and the input for the drawing
from root. So the following code is function then.

def onMouseMove(event):
  ax1.lines = [ax1.lines[0]]
  ax1.axhline(y=event.ydata, color="k")
  ax1.axvline(x=event.xdata, color="k")

def updateData():
  global level1, val1
  clamp = lambda n, minn, maxn: max(min(maxn, n), minn)
  yield 1 # FuncAnimation expects an iterator

def visualize(i):
lineVal1.set_ydata(val1)
return lineVal1

My question is. Is my way to embedd the code in Tkinter right? Or its better
to declare the diagram functionalities outside the class and only draw into
the class?

Best regards from Stefan

Stefan,

On a quick skim that does not look wrong.

I would not use globals and have the callbacks be methods on
your BOStrab_Fahrzeugeinschraenkung class.

Hi Thomas,

thank you for answerring. I have already developed further. Here is my
current code.

def PlotFrame(self):

    self.fig = Figure (figsize=(5,4), dpi=100)
    self.ax = self.fig.add_subplot(111)
    self.ax = self.fig.add_subplot(111) #fuer 2d-Plot
    self.ax.set_title('Definition der LRUGL')
    self.ax.set_xlabel('Fahrzeugbreite y [mm]')
    self.ax.set_ylabel('Fahrzeughoehe z [mm]')
    self.ax.axis([-2000,2000,0, 5000])
    self.ax.grid(True)

    self.canvas = FigureCanvasTkAgg(self.fig,self)
    self.toolbar = NavigationToolbar2TkAgg(self.canvas,self)
    self.toolbar.update()
    self.plot_widget = self.canvas.get_tk_widget()
    self.plot_widget.pack(side=tk.TOP, fill=tk.BOTH, expand=1)
    self.toolbar.pack(side=tk.BOTTOM, fill=tk.BOTH, expand=1)

self.ax.plot(np.zeros(100))

def onMouseMove(event):

        self.ax.lines = [self.ax.lines[0]]
        if event.xdata and event.ydata: # python3 often has None
            self.ax.axhline(y=event.ydata, color="k") #(y=event.ydata,
color="k")
            self.ax.axvline(x=event.xdata, color="k") #(x=event.xdata,
color="k")
        self.canvas.show()

self.canvas.mpl_connect('motion_notify_event', onMouseMove)
self.canvas.show()

def fig_ax_request():
publish('FIG,AX',self.fig,self.ax)

subscribe('REQUEST_FIG,AX',fig_ax_request)

def DrawPlot(self):

def test_plot():

self.ax.imshow(np.random.normal(0.,1.,size=[1000,1000]),cmap="hot",aspect="auto")
self.fig.canvas.draw()

self.buttonAAA['command'] = test_plot

    def get_fig_ax(fig,ax):
        self.fig = fig
        self.ax = ax

subscribe('FIG,AX',get_fig_ax)
publish('REQUEST_FIG,AX')

Now i have a table for input and an embedded diagram in tkinter canvas.
This code above is only for testing. I want the functionality that i can
write values in the table and let it simultanously paint into
matplot-Canvas. Hav eyou some suggestion or imrpovements to do that ?

Best regards from Stefan
