My Arduino is sending 0 or -127 to the charts.. how do I delete these values or prevent them from being displayed..

 

I'll modify my sketch to prevent such mix/max values from being updated to thingspeak..

If you add min and max parameters to the chart URL you can filter numbers above the max and below the min value.

Example:

(no min/max)

https://api.thingspeak.com/channels/3/charts/1?round=2&average=10

(min/max)

https://api.thingspeak.com/channels/3/charts/1?round=2&average=10&min=70&max=75
