Create a Card in Power BI Approach 2
In order to create one, first, click on the Card present in the Visualization section. It will create a Card with dummy data, as shown in the screenshot below.
Let me drag the English Country Region Name (Dimension data) into the Fields section. As you can see, the card in Power BI desktop shows the First Country Name as the Card value.
You can change the First function to any other Power BI supporting function.
Next, let me remove the Country Name and add the Sales Amount to the Fields section.
By default, it uses the default aggregated function called SUM. But, you can change this aggregate function as per your company requirement.
Let me do some quick formatting to this Card.
NOTE: I suggest you refer to the Format Card article to understand the available formatting options.
