Simple script which takes CSV Data either from stdin or a given filename and plots a graph out of that.
|
||
|
|
You might want to retrieve CSV Data by executing the following command:
|
||
|
|
|
||
|
|
mysql -h button-back -u anonvoting -p foundation -B -e 'SELECT DATE_FORMAT(first_added, "%Y-%m") AS date, COUNT(*) as joined FROM foundationmembers GROUP BY date;' | sed 's/\t/","/g;s/^/"/;s/$/"/;s/\n//g' | awk 'FNR>1'
|
||
|
|
|
||
|
|
mysql -h button-back -u anonvoting -p foundation -B -e "SET @start = '2009-01-01', @end = '2009-08-30'; SELECT DATE_FORMAT(DATE_ADD(last_renewed_on, INTERVAL 2 YEAR), '%Y-%m') as date, COUNT(*) as dropped_out FROM foundationmembers WHERE last_renewed_on >= DATE_SUB(@start, INTERVAL 2 YEAR) AND last_renewed_on <= DATE_SUB(@end, INTERVAL 2 YEAR) GROUP BY date;" | sed 's/\t/","/g;s/^/"/;s/$/"/;s/\n//g' | awk 'FNR>1'
