This is pretty easy with a PivotTable once we know about the group trick!Īll we need to do is right-click any day cell in the PivotTable and select Group. The final step is to create the intervals, or bins. For our histogram we want to change the math to count, so we right-click any PivotTable value cell and select Summarize Values By > Count. This is shown below.īy default, Excel will sum the Amount field since it is numeric. We Insert > PivotTable, and then insert the Days field into the ROWS area and the Amount field into the VALUES area. To summarize the data table and have Excel automatically place the data into intervals, we create a PivotTable. We have exported the open invoices from our accounting system, and stored the data in a table ( Insert > Table). We have defined an aging “As Of” date and then computed the number of Days between the invoice date and the As Of date with a simple subtraction formula. Depending on what you are charting, you could add blank value cells to the table for the missing interval labels, or, use a different solution including COUNTIFS, FREQUENCY, or the Histogram tool.Īssuming our data contains values for all needed intervals, it is pretty quick and easy to create a PivotTable and related PivotChart. That is, if there are no invoices falling between 31-60 days, that interval will be excluded from the PivotTable and PivotChart. PivotTables only display values that exist in the data source. Once the data has been summarized, it is fairly easy to plot.Īs with anything in Excel, there are several ways to summarize the data, and with a little trick, we can use a PivotTable.īefore we jump right in, there is a note of caution. Typically, the most time-consuming part of creating a histogram is summarizing the data and computing the number of items within each interval. We would like to create a chart that displays the invoices based on their aging status, grouped into equal intervals, 1-30, 31-60, 61-90 days, and so on. We have exported a list of open invoices from our accounting system. In this post, we’ll create a histogram using a PivotChart. For example, the number of days with a high temperature between 71-80 degrees, 81-90, and 91-100, the number of students with test scores between 60-69, 70-79, 80-89, or the number of invoices that are due in 31-60, 61-90, or 91-120 days. A histogram graphically displays the number of items that fall within equal intervals, or, bins.
