If you click on one of the buttons above, it may take up to 10 seconds to update the chart.
The most recent data point (the rightmost one) starts at zero and moves higher every 10 seconds.
Hover your mouse pointer over a data point to see its value.
What does it mean?
Seconds: This is the most detailed chart. Horizontal axis is the time.
The value shows the power rating at that moment. For
example if the value is 100 Watts, this means that if the power level stayed constant at that level for one hour,
then 100 Watt Hour of energy would have been used. 100 data points are displayed.
The value shown is the rate at which the energy is being used.
Minutes: Some of the detail is lost in this chart. 100 minutes of data is displayed. The
value shows the actual energy used in that minute times 60. If the power level stayed exactly
the same for 60 minutes, that is the amount of energy that will be used.
Hours: More details are lost in this chart. 100 hours of data is displayed. The value
displayed is the actual Watt Hours of energy used in that hour.
Days: This chart shows the actual energy used in that day in Watt Hours.
What is Watts and Watt-Hours?
If we use an analogy of driving a car, the speed of the car would be like Watts,
and the distance we travel would be like Watt-Hours. In this case, Hours and Days
above would be like two trip-meters reset at each Hour, and each Day. Odometer would
be like the total number of Watts tracked by this system.
Known Problems
The tooltip does not show the right value in 'Seconds' mode.
X axis unit labels are overlapping each other and thus becoming unreadable.
