LS,
I'd like to plot multiple motion detectors in one graph.
Reason for that is to allow me to image on the movement in the house, determining whether someone is there. Eventually a variable is set "HouseInUse", based on the different motion sensors.
Plotting those as 0 or 1 implies any of the detected motions is shown on the y-axis, though multiple variables are written on the 0 or 1 scale. X-axis in time.
When no motion is detected all variables are plotted on the 0 value of the scale.
I assume using the multiplier per variable allows me to plot (for example) a 2, 3 or 4 on the y axis.
However, using that setup, when no motion is detected all the variable are still plotted on 0, making the graph impossible to interpret. All *, ^, + are on the same line, making it impossible to distinct.
I thought about a solution to cover this is to add 1 per motion detector, so the first one +0, the second one +1, the third +3, etcetera.
This would allow me identify which variable (motion) is on or off during a specific time span.
As far as I understand there is only the option to multiple, which will be useful for the ON state, though Off is still plotted on the 0 line. All motion detector plotting on 0 again makes the interpretation of the graph impossible.
Is there another way covering this?
Thanks for the input,
