Generating Flux Tally plot with Microsoft Excel.

Hello, I am trying to generate flux tally with the below code

<?xml version="1.0"?>

regular

50 1

<lower_left>-70.71 -70.71</lower_left>

70.71 70.71

1

1

flux

where 70.71 is the radius of my reactor. Now, In the tally.out file I got something

============================> TALLY 1 <============================

Mesh Index (1, 1)

Total Material

Flux 12.2047 +/- 6.30332E-02

Mesh Index (2, 1)

Total Material

Flux 11.7069 +/- 6.12077E-02

for the first two mash. And the rest is 0. I want to plot the neutron flux from center to radius of the reactor. I am not getting such values. Am I missing something? If I had the value I would use them to generate a downward plot in Microsoft excel. But, so far I am stuck on not getting the proper data in flux tally. Please help.

It will also be helpful if someone explains to me how the open create the mash tally?
