Figure 9
The graph is titled “School 1-A”. The horizontal axis shows dates ranging from 02.08.2022 to 03.02.2022. The vertical axis is labeled “Temperature (degrees Celsius)” and ranges from 0.00 to 25.00 in increments of 5.00 units. A legend identifies four data series: A blue dotted line labeled “Environment”. An orange solid line labeled “Datalogger”. A green solid line labeled “Calibrated”. A red dotted line labeled “Before Calibration”. The blue “Environment” line starts at 4.00 degrees Celsius, fluctuates between 2.00 and 13.00 degrees Celsius with repeated spikes and valleys throughout the time period, and ends at 7.00 degrees Celsius. The orange “Datalogger” line starts at 18.00 degrees Celsius, fluctuates between 18.00 and 26.00 degrees Celsius with repeated peaks and valleys throughout the time period, and ends at 25.00 degrees Celsius. The green “Calibrated” line starts at 18.00 degrees Celsius, fluctuates between 18.00 and 26.00 degrees Celsius with repeated peaks and valleys throughout the time period, and ends at 25.00 degrees Celsius. The red “Before Calibration” line starts at 17.00 degrees Celsius, fluctuates between 15.00 and 24.00 degrees Celsius with repeated peaks and valleys throughout the time period, and ends at 23.00 degrees Celsius.
