Usually in Power BI, we build visuals by dragging and dropping fields onto the report page to form our axis and values. If we want to answer this question, we're faced with a problem. Note here that the Month column is a date type field, but I've changed the formatting to make it more readable.īased on the data in Fact Sales Snapshot, we've been asked to answer this question: For how many months did each store sell below their sales targets? Since the table contains a snapshot of the sales up to the end of each month, let's call this table Fact Sales Snapshot. This dataset contain the Sales and Sales Targets, with an underlying table that looks like this… We have been given data about how each of the company's 16 stores have performed in each month of the 2019-2020 financial year. In this example, we will be answering questions about a hypothetical retail company based in Melbourne, Australia. Histograms aren’t just useful in statistics - they can also be used effectively in business scenarios to provide useful insights. Using a histogram to answer business questions you don't need to include ages 0-9 when describing staff at a company. The context of the situation may make it reasonable to omit empty bins at the top or bottom end of the distribution if they are not between two nonempty bins, e.g. Histograms include bins that have a count of zero. We’ll only focus on histograms using individual integer values, since there are a number of articles already written by others on using binning for segmentation. An item represented in a column of a histogram could have any value within that bin. The values on the x-axis can be individual values (ages 0, 1, 2, 3, etc.) or binned values (ages 0-9, 10-19, 20-29, etc.).
names of groupings), and the y-axis contains frequency / count data. numbers) rather than categorical values (i.e. The x-axis contains continuous values (i.e. Histograms have a number of particular features that not all column charts have. While you may be used to column charts that display financial measure like profits, histograms are column charts that give you information on the frequency of values, often times using a COUNT measure in Power BI. For many people, they may seem like one in the same, but while all histograms are column charts, not all column charts are histograms (similar to how all humans are mammals, but not all mammals are human). Histograms, quite simply, are a type of column chart. What is a histogram again? Isn't that just a column chart? We’ll start with a simple implementation, then build out a more sophisticated one with additional flexibility and insight into our scenario.

However it’s not immediately obvious how to set them up in Power BI, so we’re going to go through a few techniques for how to build them to address a business scenario. Histograms can be useful not just within statistics, but also for answering business questions. They can show you the most common values, the outliers, and the spread of your values, all at a single glance.
A histogram is a common tool in statistics to describe the distribution of values across a dataset.
