# A tribute to Pi

Pi (Π) day is celebrated on 14 March every year.
Θ– Θ

However, this year, that day shall remain etched in history,
and in our memories too; For once in a lifetime,
our own beautiful pi, is bestowed with this unique
celestial event, where it heartily celebrated its birthday
coinciding with the day of the year.

(3.14159 is rounded off as 3.1416,
which is 14 of March, 16).

Though many brilliant artworks on Π exists, [such as this by Martin Krzywinski], a contribution from me can be seen in this excel file, where you can see the randomness of the decimal digits, in the form of a line chart, by pressing the F9 function on the keyboard, with a simple flick.
Θ– Θ

The 10,000 decimal digits of Π was taken from here. You will see from that the frequency of digits is very similar yet the numbers do not seem t0 converge:

(a video by Numberphile on the one million digits of is worth mentioning here.). If you are interested in Excel formulas, you would like to check how I have used the Offset function to randomly select a row for the series that’s  just been plotted.
Σ– Σ

Also, using conditioning formatting (press F9 to randomise the shapes), one can generate artwork that is very personal. I have chosen ‘Yellow‘; for numbers: 0 -3; ‘Blue‘ for numbers: 4-6; ‘Orange‘ for numbers: 7-9 and used the repeat function to add dashes to a cell. It looks pretty indeed. You can also see the sparkline in the excel file to get a quick glance at the variations of points in the 1200 or so rows. Excel file
