Is there a way to set multiple Y-Axis Scales on a History Graph? I am using a Photoresistor to monitor light level in a room, and a simple magnet proximity sensor to monitor a door (open/closed). I am able to get the data into the History Graph with no problem. The issue is, that because the light level sensor values go from 0 - 1000(ish), I cannot really see the change in the Proximity sensor value (0 or 1). I would like to have two (possibly more) Y-Axis Scales so I can see the changes in the proximity sensor better. Is this possible?
Not at the moment. Your options are either have two history graphs or map all values to the similar scale in your sketch.
Ok. Thanks for confirming what I had already suspected. I am currently using two history graphs. The trouble with this is that my project takes up two tabs. It’s not that big an issue, as I put both history graphs on the second tab. I just now have a lot of blank space on the first (time to expand some buttons). The other issue is the cost of the extra history graph (900 energy). Hopefully this feature gets added in the future (fingers crossed).
Oh BTW, Love this APP.
multiply the value of the proximity sensor by 1000 or so in the code before sending to blynk server, than you will have a readable graph.
