Diagram Line Charter For Free

A line graph?also known as a line plot or a line chart?is a graph that uses lines to connect individual data points. A line graph displays quantitative values over a specified time interval.

To draw a line graph, first draw a horizontal and a vertical axis. Age should be plotted on the horizontal axis because it is independent. Height should be plotted on the vertical axis. Then look for the given data and plot a point for each pair of values.

A frequency diagram, often called a line chart or a frequency polygon, shows the frequencies for different groups. The frequency chart below shows the results of the table. To plot a frequency polygon of grouped data, plot the frequency at the midpoint of each group.

1 Line Graphs, Bar Graphs, and Frequency Polygons. Data from a frequency table can be graphically pictured by a line graph, which plots the successive values on the horizontal axis and indicates the corresponding frequency by the height of a vertical line.

They are: Simple Line Graph: Only one line is plotted on the graph. Multiple Line Graph: More than one line is plotted on the same set of axes. A multiple line graph can effectively compare similar items over the same period of time. Compound Line Graph: If information can be subdivided into two or more types of data.

Step 1: Identify the variables.Step 2: Determine the variable range.Step 3: Determine the scale of the graph.Step 4: Number and label each axis and title the graph. Step 5: Determine the data points and plot on the graph.Step 6: Draw the graph.

A bar graph shows a comparison among categories. A pie chart is used to represent and compare parts of a whole. A bar graph that shows data in intervals is called a histogram. A line graph is used to display data that changes continuously over periods of time.
