ax.format_coord is the function that formats the numbers shown in the red ellipse of your picture. Given that knowledge you can put anything in that red ellipse you want.

Hi Jody,
Did you check the picture I attached? You are still in the wrong direction about what I want???..
Please check the digit in the red ellipse in my picture!!!

Maybe?
def format_coord(x, y):
return 'x=%4.4e, y=%4.4e?%(x, y)) # or whatever formatting you want
ax.format_coord = format_coord

Hi Jody,
I apologize if I said it backwards!
I think you now get what I want.
I tried your code. It didn?t work still.

Did you try:
from matplotlib.ticker import ScalarFormatter
fmt_no_sci = ScalarFormatter(useOffset=False)
fmt_no_sci.set_scientific(True) # NOTE True instead of False.
I think you just said it backwards: You want scientific ntoation, not decimal notation.

Hi Jody,
Please check the red ellipse in the picture.
I want the value 1.85092e+06 to be 1850922 in the red ellipse in the following picture.
fmt_no_sci = ScalarFormatter(useOffset=False)
fmt_no_sci.set_scientific(False)
# ax.fmt_xaxis = fmt_no_sci
fig = plt.figure()
ax = fig.add_subplot(111)
ax.plot(testdata)
ax.fmt_xaxis = fmt_no_sci
plt.show(0)
The x axis value displayed at the left-bottom corner of the figure is still scientific notation, but not decimal notation.
Please check the x axis value displayed at the left-bottom corner of the figure in the red circle.

HI Eric,
Did you review the picture attached in my former email?
I suspect you go to the wrong direction about what I want to ask.
Best Regards,

Hi Ardeal,
Its not clear to me what you want. Do you want 3.2 x 10^3 instead of 0.0032? The former is scientific and the latter decimal.
Thanks, Jody

I'm getting a different result, but on the basic point we now agree:
the ScalarFormatter is not the right tool for this. What you need is a function that takes a number and returns the kind of string you want.
Examples:
def format_as_int(num):
return str(int(num))
def format_float_no_sci(num):
return "%f" % num

Hi Eric,
I added your code to my code:
*from *matplotlib.ticker *import *ScalarFormatter
fmt_no_sci = ScalarFormatter(useOffset=False)
fmt_no_sci.set_scientific(False)
/# ax.fmt_xaxis = fmt_no_sci
/prow = 4
pcol = 1
pidx = 0
fig = plt.figure()
pidx += 1
axx = fig.add_subplot(prow, pcol, pidx, ylabel=*'rawdata'*)
axx.plot(np.abs(testdata))
axx.fmt_xaxis = fmt_no_sci
The *x axis value displayed at the left-bottom corner of the figure*is
still scientific notation, but not decimal notation.

Hi,
If I put the mouse on the figure, x and y axis are displayed on the
left-bottom corner of the figure.
but the x axis is displayed as scientific notation, I want it to be
displayed as decimal notation.
how to make x axis or y axis values displayed as decimal notation
on
the left-bottom corner?
*Best Regards,*

Something like this, assuming your Axes is ax:
from matplotlib.ticker import ScalarFormatter
fmt_no_sci = ScalarFormatter(useOffset=False)
fmt_no_sci.set_scientific(False)
ax.fmt_xaxis = fmt_no_sci
