Hi,
Another issue, in this that is happening which is far more important from
the perspective that I am looking at, is that when I click the button
twice, two graphs get created one below the other.
I tried adding a delete("all") statement as shown below.
Code:
def Submitplot():
print "Create plot"
print concsim.get()
f = Figure(figsize = (5,5), dpi = 80)
canvas = FigureCanvasTkAgg(f, simroot)
canvas.get_tk_widget().delete("all")
a = f.add_subplot(111)
a.plot([1,2,3,4,5],[10,11,12,14,15])
canvas.show()
canvas.get_tk_widget().pack(side = TOP)
toolbar = NavigationToolbar2TkAgg(canvas, simroot)
toolbar.update()
canvas._tkcanvas.pack(side = TOP)
Button(simroot, text = "Submit and Plot", command = Submitplot).pack(side =
TOP)
But this still does not clear the earlier made canvas and creates another
graph at the bottom. Can someone please tell me what I am doing wrong here?
I would really appreciate it.
I have also added the image as to how the two plots look like.

Thankyou
