Column Chart Showing Total Sales by Store Location

Click Add Chart.

Select the sample_supplies.sales data source.

In the Select Data Source modal that appears:

1. Click the Project tab.

2. Click the name of the deployment that contains the sample data source.

3. Click the sample_supplies database. The database's data sources appear.

2. Click Select on the sales data source.

Select the Chart Type

In the Chart Type dropdown, select Stacked Column.

To render a stacked column chart, Atlas Charts creates a bar or column for each distinct value in the category encoding channel field.

Add the desired fields to the proper encoding channels.

1. Drag the storeLocation property from the Fields section of the Chart Builder view to the X Axis encoding channel.

   This tells Atlas Charts to create a column for each storeLocation value in the dataset.

   Note

   Atlas Charts infers the data type of each field and provides symbols to easily determine these data types when building your chart. These symbols can help ensure your chart renders as expected by using proper data types for each encoding channel. For example, the calendar icon next to the saleDate field signifies that this field is a timestamp.

2. In the Fields section click the items field to expand the items object and view its properties.

3. Drag the items.price field to the Y Axis encoding channel.

   This tells Atlas Charts to use the items.price field for the chart's aggregation.

4. In the items dropdown below Array Reductions, select Unwind array.

   Array reductions dictate how to process an array so its elements can be visualized. The unwind array option creates a new document for each element in the array, so each item's price is added to the total for that store.

5. In the Aggregate dropdown, select sum.

   The $sum aggregation operator adds the prices of all items per store together to display the chart.

Title your chart.

1. Hover over your chart title above the center of the chart and click the pencil icon.

2. Copy the following into the chart title input:

   Total Sales ($) by Store Location

3. Click the check mark to save your title.
