I write increasing values to VirtualPin. I add SuperChart to see history. I need to compare values between measures: see columns upper zero and lower. Like this: http://criticaltosuccess.com/wp-content/uploads/2014/05/IMG-Difference-Chart-Actual-v-Target-01.png I see straight SuperChart settings 'delta', but I can't understand how it works.
Is it possible?
If it is not possible, maybe I should calculate deltas on the device and send to another pins? The better way to do this is read previous values from virtual pin, calculate delta, send new data. I don't see API for reading values..
Again, please use Blynk community forum for such questions. You may just copy-paste it
