The concept and reason of temperature statistics are obtained.

Drawing temperature statistical chart is an effective visualization method, which can clearly show the change of temperature with time or place. This graph is usually represented by a line chart or histogram, in which each data point represents the temperature at a specific time or place. In order to accurately reflect the temperature change, this diagram needs to include the title, axis label, data label and other elements.

Reason:

1. data visualization: the temperature statistical chart can visually display the distribution and change of temperature data in a graphical way. In this way, observers can quickly understand the data and discover the trends and patterns in it.

2. Convenient comparison: If the temperature data of multiple places or times are displayed on a map, observers can compare them conveniently. For example, the observer can clearly see in the picture where the temperature changes more violently, or which time period has the highest temperature.

3. Reveal the trend: By connecting data points and drawing the trend line, the temperature statistical chart can help observers identify and predict the changing trend of temperature.

4. Discovering anomalies: If a data point is obviously higher or lower than other data points, or there is a sudden jump or drop, this may mean that there is an anomaly. By observing these abnormal points, observers can further explore the possible reasons.

In a word, the temperature chart is a very effective tool, which can help us to better understand and analyze the temperature data and find the laws and anomalies in it.
