How to draw a statistical chart of temperature broken line
First, make a table and set the highest and lowest temperature values corresponding to the date; Select a data source and insert a line chart; Add data identification; Select the Y axis, and set the abscissa to cross the "Maximum Axis Value" to display the X axis to the top; Modify the title and add gridlines.
Introduction of broken line statistical chart:
A statistical chart that shows the increase or decrease of statistics by the rise or fall of broken lines is called a broken line statistical chart. The statistical graph of broken lines shows the increase and decrease of data with the fluctuation of broken lines. It can not only represent quantity, but also reflect the change of data. Line charts can be divided into dynamic line charts, dependent line charts and time distribution line charts.
People often use line charts to describe the dynamics of the overall indicators of statistical matters, the interdependence between research objects and the distribution of various parts in the population. Statistical chart is a tool to express the relationship between various quantities and their changing geometric figures with points, lines, surfaces and bodies.
Various charts showing the size and changes of statistical data. There are bar charts, fan charts, line charts, pictograms, etc. In statistics, the method of representing statistical data with statistical graphs is called statistical graph method. Its characteristics are: concrete image, concise and vivid, easy to understand and clear at a glance.
Mathematical significance:
The broken-line statistical chart is a graph that shows the changing trend of statistical data with the rise and fall of broken lines, also called curve statistical chart. Line charts can be divided into dynamic line charts, dependent line charts and time distribution line charts. People often use line charts to describe the dynamics of the overall indicators of statistical matters, the interdependence between research objects and the distribution of various parts in the population.
In primary school mathematics, only dynamic line charts are generally taught, which refers to the figures showing a certain trend when the data of statistical items change with time. When drawing a dynamic line chart, we should first establish a plane rectangular coordinate system, with the horizontal axis representing time and the vertical axis representing the number of statistical changes, draw corresponding coordinate points on the coordinate plane, and connect the points to form a line chart with quantitative change trend.
