3 Examples of “Line Graph in Excel Not Working” Issue with Solutions

Problem 1: Line Graph Command Is Producing Two Lines

In the case of showing two lines in a chart, you need to convert one series of data (in this example, Year) into text format. Look at the following image. We have plotted this chart for showing different sales in different years. Inserting a line chart, we get the two lines in the chart.

Line Graph Command Is Producing Two Lines

Our goal is to omit the Year line from the chart.


  • For this, we need to convert the Year data into text format. We can simply do this by selecting data and putting Apostrophe in front of it as shown in the image below.

  • Next, you need to drag the Fill Handle to the remaining cells to convert all the Year data into text format.

Here is the Year data converted to text data.

  • Now, insert the double-line chart again. At this time, you will see the one line that is the Sales line.

Problem 3: Line Not Visible on Chart

Consider a chart with year on X-axis and COMBO Y axis in which data is displayed as four series (three lines on the left Y axis and one bar graph on the right Y axis). The lines are all good except for one that isn’t visible. There is a legend for the missing line, but not the actual data line, showing up as part of the data series. You may have tried selecting data/hiding cells/connecting data points with lines, but are not able to get the last data to appear. There is a solution for you discussed below.


After selecting the chart, the Chart Tools group appears on the right-hand side of the Ribbon, including the Design and Format tabs. In the Format tab, you can select different elements of the chart using a dropdown menu on the left. You should see little handles where the points should be if you select a series you cannot see.
