One helpful tip in improving dashboard presentation is by creating combination charts. Excel allows us to combine different chart types in one chart. This article assists all levels of Excel users on how to create a bar and line chart.

Bar Chart with Line
There are two main steps in creating a bar and line graph in Excel. First, we insert two bar graphs. Next, we change the chart type of one graph into a line graph.
Insert bar graphs
- Select the cells we want to graph
Figure 2. Selecting the cells to graph
- Click Insert tab > Column button > Clustered Column

Two column charts or vertical bar charts will be created, one each for Quantity and %Reduction.
Figure 4. Vertical Bar Graph
Change bar graph to line graph
We want to present %Reduction as a line graph.
- We right-click on the series “% Reduction” and select Change Series Chart Type
Figure 5. Change Series Chart Type in Menu Options
- The Change Chart Type dialog box will appear. Select Line > Line with Markers

The %Reduction bar graph is now presented as a line graph. However, since the values are less than one, the line graph values are too close to the horizontal axis to be visually significant.

The work-around is to plot the line graph on a secondary axis.
- Right-click the line graph and select Format Data Series.
Figure 8. Format Data Series Option
- The Format Data Series dialog box will pop-up. Tick Secondary Axis in Series Options.

We now have a combination bar and line graph.

Next let us clean up our bar and line graph by doing the following:
- In Format Data Series, choose Marker Options > Marker Type > None
- Marker Color > Solid Line > Orange
- Delete the gridlines
- Add a chart title in Layout tab > Chart Title > Above Chart, then type “Rejects”
