How to draw a temperature line chart
The temperature line chart is drawn as follows:
First, create a table and set the maximum and minimum temperature values corresponding to the date; select the data source and insert the line chart; add data markers; select For the Y axis, set the abscissa to cross the "maximum axis value" to display the X axis above; modify the title and add grid lines.
Introduction to line statistical charts:
A statistical chart that uses the rise or fall of a polyline to represent the increase or decrease in statistical quantities is called a line chart. Line statistical charts use the ups and downs of the polyline to represent the increase or decrease in data. It can not only express the quantity, but also reflect the increase or decrease of data. Line charts can be divided into dynamic line charts, dependency line charts and frequency distribution line charts.
People often use line charts to depict the dynamics of overall indicators of statistical matters, the dependence between research objects, and the distribution of various parts of the overall. Statistical charts are tools that use points, lines, surfaces, bodies, etc. to draw geometric figures to represent the relationships between various quantities and their changes.
A general term for various graphs that show the size and change of statistical numbers. There are bar charts, sector charts, line charts, pictograms, etc. In statistics, the method of using statistical graphics to represent statistical data is called statistical graphical representation. Its characteristics are: concrete image, concise and vivid, easy to understand and clear at a glance.
Mathematical meaning:
A line chart is a graph that uses the rise and fall of a polyline to represent the trend of statistical data changes. It is also called a curve chart. Line charts can be divided into dynamic line charts, dependency line charts and frequency distribution line charts. People often use line charts to depict the dynamics of overall indicators of statistical matters, the dependence between research objects, and the distribution of various parts of the population.
In primary school mathematics, only dynamic line graphs are generally taught, which refer to graphics showing a certain trend as the data of statistical items changes with time. When drawing a dynamic line chart, you must first establish a plane rectangular coordinate system. The horizontal axis represents time, and the vertical axis represents the number of changes in statistical items. The corresponding coordinate points are drawn on the coordinate plane, and each point is connected to form a line chart of the quantitative change trend.
