It addresses some questions we have
25 / 32
- Our solution to these questions is to use calendar plot.
- This calendar format should be familiar to you. Bc it appears everywhere, on your wall, on the desk or on your elec dev

- High demand in Jan and winter time, no more than that
30 / 32
- Lemme just switch to the calendar display. Different story. During the summer time, particularly in Jan, one peak in the late afternoon due to the air conditioning use. As the temp goes up, the elec use goes up. By contrast, experienced two peaks in the Winter, one in the morning and the other on in the night for the heater use.
- Weekday and weekend
The 3rd or more examples are there for you to add and explore.
