On a column chart, the height of each column is proportional to the value it represents (that is, a smaller number is shorter and a larger number is taller). Its purpose is to show the actual and comparison values for each month in the period you have selected. Similar to the area chart, the column chart is good for visualizing non-segmented metrics, like operating income and cash flow.
Column charts on the overview
On the overview, the column chart has two sizes:
The chart shows your monthly actual values as blue columns and the comparison values as gray background columns. These charts have no axis labels and the smallest one doesn't have a legend. They are just meant to show the general trend for your actual results vs. comparison period. You can click on these smaller overview charts to see the detailed trend view of the chart.
Column charts on the trend view
On the trend view, the column chart provides some additional detail:
- Comparison selector: The comparison selector allows you to choose whether you are comparing your actual results to the forecast, the previous period, or the previous year:
- Hover pop-up: When you hover over a month on the chart, the actual and comparison values (and percent difference) are shown in a popup. The percent difference is also shown with a green arrow (if the change is good news) or a red arrow (if the change is bad news):
