We want to see an Area Chart with the ON STATE corresponding
to a y-axis value of 1 and the OFF STATE corresponding to a y-axis
value of 0.
We might have a series of data like this:
23May08 11:43:35 ON
23May08 11:43:39 OFF
01Jun08 12:55:03 ON
05Jul08 06:32:01 OFF
08Sep08 08:00:02 ON
In reality this data could show a state change at any time.
Note in the first instance, above, the state was ON for only 4
seconds. We need to see that on the graph, as a visible line, even
though the graph might be displaying for six months. We need to
display this graph for a defined period with each ON state change
being represented by the area chart showing as 1 on the y-axis.
So can we pass this data to a flex chart and have it logged
efficiently and then display the corresponding chart? I would hate
to have to generate millions of values to achieve this. Four months
of one second data is about 10,368,000 lines of data!
