The tutorial explains the process of making a line graph in Excel step-by-step and shows how to customize and improve it. The line graph is one of the simplest and easiest-to-make charts in Excel. However, being simple does not mean being worthless. As the great artist Leonardo da Vinci said, 'Simplicity is the greatest form of sophistication.' Line graphs are very popular in statistics and science because they show trends clearly and are easy to plot.

So, let's take a look at how to make a line chart in Excel, when it is especially effective, and how it can help you in understanding complex data sets. • • • • • • • • • • • Excel line chart (graph) A line graph (aka line chart) is a visual that displays a series of data points connected by a straight line. It is commonly used to visually represent quantitative data over a certain time period. Typically, independent values such as time intervals are plotted on the horizontal x-axis while dependent values such as prices, sales and the like go to the vertical y-axis. Negative values, if any, are plotted below the x-axis. The line's falls and rises across the graph reveal trends in your dataset: an upward slope shows an increase in values and a downward slope indicates a decrease. When to use a line graph Line charts work well in the following situations: • Good visualization of trends and changes.

Of all the variety of Excel charts, a line graph is best suited for showing how different things change over time. • Easy to create and read.

A multiple line graph can help you reveal relationships between two or more variables.

More values would make your chart more difficult to read. • Best for continuous data. If you have discrete data in separate columns, use a • Not suited for percentages and proportions. To display data as a percentage of the whole, you'd better use a or a stacked column. • Not recommended for schedules.

In this example, we are going to do a single line graph, so our sample data set has the following two columns: • Select the data to be included in the chart In most situations, it is sufficient to select just one cell for Excel to pick the whole table automatically. If you'd like to plot only part of your data, select that part and be sure to include the column headers in the selection. • Insert a line graph With the source data selected, go to the Insert tab > Charts group, click the Insert Line or Area Chart icon and choose one of the available.
