My understanding of an Ogive graph is that it is a line graph that shows how the cumulative distribution of some data accumulates over time in terms of proportions. The minimum proportion is 0 at time 0 and 1.00 (or 100%) at the final time.
I suppose that over a 22 year period a plot like this could be drawn, but its appearance and utility would be very dependent on the time scale that was used. If data are summarized over a full year there would be 23 points starting at (0,0) and ending at (22, 1.00). The points would be connected and show a trend as it changed by year. If you used months, then there would be 22 x 12 = 264 + 1 data points and teasing out details of a trend given that detail could be difficult. The data would run from (0,0) to (264, 1.00). The y-axis, showing the cumulative proportions of data would require much finer definition in order to make sense.
Another issue is that as soon as the 23rd year begins, new data begins to accumulate and the existing calculations will no longer be valid.
