This is a graphical representation of the numbers attending Holy Mass as a total in the four parishes. The date is on the x-axis, the number of attendees on the y-axis. You can see the previous number of people who attended Holy Mass at the top.
The blue line is the actual number of people week by week, the red point, which will become a line as figures are added, is a simply four point rolling average.
