Power BI Bins or buckets help create a range of data, similar to SQL Buckets. Let me show you how to create bins with an example.
For this Power BI bins demonstration, we will use the SQL Data Source we created in our previous article. So, Please refer Connect to the SQL Server article to understand the Data Source.
Create Bins in Power BI
To visually demonstrate these bins, we will create a Table. As you can see from the screenshot below, we created a simple Table by dragging the Product Key and Sales Amount columns.
I suggest you refer to Create a Table and Format Table article to understand the steps involved in creating and formatting a Power BI Table.
Please select the field that you want to use as a bin and right-click on it to open the context menu. Then, select the New Group option from the menu.
Clicking the New Group option opens the following window.
- Name: Specify the Power BI Bin name
- Field: Field or Column that you used for binning
- Group Type: List (group) or bin.
- Bin Type: There are two options such Size of Bins or the Number of Bins
- Min and Max Value: Minimum and maximum values present in the selected Fields. Here is the Product Key.
If you selected the Bin Type as the Size of Bins, then you have to specify the Bin size (static Number)
Alternatively, if you selected the Bin Type as the Number of Bins, you must specify the bin count. Here, Bin size depends upon the Bin count.
Let me select the Bin size as 20 and click OK. It means each bucket size is 20
Now you can see the newly created bin under the Product table.
Let me add that bin to this table. From the below screenshot, you can see that the product Key value is 220 for the keys between 220 to 240
Edit Power BI Bins
Please select the bin you want to edit and right-click on it to open the context menu. Select the Edit Groups option from it
Clicking the Edit Groups option opens the following window. Use this window to change as per your requirement.
Delete Bins in Power BI
Please select the bin you want to delete and right-click on it to open the context menu. Select the Delete option from it
Click the Delete button to confirm the delete operation.
Create Bins in Power BI Example 2
To demonstrate the Bins, we created a Column chart that shows Color wise sales. This time we create a bin on Sales Amount
Right-click on the Sales Amount and select the New Group option from the context menu. As you can see from the below screenshot, we defined the Bin size as the 357.2655
Let me add this new Sales Amount bin to the Column chart legend section.
Let me Edit it, and change the Bin type to Number of Bins, and Bin count to 3
Now you can see each bar in the column chart is divided by a bin of count 3.
