Highlight Parts of a Line Chart Posted on May 6, 2016 July 25, 2019 by goodly - The other day I was gazing at a business metric (a line chart) and I felt the need to just select a part of the line chart and focus on what happened during that time frame. Line graphs have a horizontal axis (the x-axis) and a vertical axis (the y-axis). We plot line graphs using several points connected by straight lines. Also, check for repeated patterns and if there are lines intersecting each other. Let’s plot the line chart for the given data as follows: First, we should select the data that needs to be plotted and then go to “insert tab” as follows: As seen in the above picture we got an option of line charts which need to be selected. They are Horizontal axis and vertical axis. The given image describes the parts of a line graph. Plot the horizontal line and vertical line select the suitable scale for both the axis. Many sources give credit for the line chart invention to Scottish engineer and political economist William Playfair. The y-axis. This curve illustrates… 4. Labels: Both the side and the bottom of the linear graph have a label that indicates what kind of data is represented in the graph. A general linear function has the form y = mx + c, where m and c are constants. These graphs are plotted as a series of points, which are later joined with straight lines to provide a simple way to review data collected over time. Use the data from the table to choose an appropriate scale. It offers an excellent visual format of the outcome data collected over time. Line graphs are drawn such that the independent data values are on the x-axis and the dependent data values are on the y-axis. A line graph is a type of chart used to show information that changes over time. x-axis: tells about labels on x-axis, which is generally time. To represent a Line graph in excel, we need 2 necessary components. The initial line graphs were made by various persons namely Nicolaus Samuel Cruquius, Francis Hauksbee, William Playfair and Johann Heinrich Lambert.
