Single number

The single number chart shows exactly one value, large and clear. It's ideal for highlighting a key metric — like the total number of customers, average revenue, or maximum score.

You can:

• Set a title and description

• Select the data column to aggregate

• Choose an aggregation method (sum, average, minimum, etc.)

Use this visualization when you want to present a key metric at a glance.

How to create a single number chart

1. Go to the Chart tab.

2. Select Single number as the chart type.

3. In the Data column field, select the column you want to summarize.

4. In the Aggregate dropdown menu, determine how the number should be calculated.

Available aggregations

When using the single number chart, you need to specify how the final number should be calculated. This is the function of the aggregation setting - it summarizes all values in your selected column.

Aggregation	How it works
SUM	Adds up all values in the column
AVG	Calculates the average (arithmetic mean)
MED	Determines the median (middle value)
MIN	Shows the smallest value
MAX	Shows the largest value

Example: If you select Count of unique values of Customer ID and SUM, it will display the total number of unique customers in your dataset.

Title and description

As always, you can:

• Change the title (by default, this is the name of your insight)

• Add a description to explain what the number means

This is particularly helpful when displaying the chart in a dashboard or report.

When to use a single number chart

Use the single number chart when:

• You want to highlight a key metric

• You're creating a summary or overview

• You prefer a simple and minimalist display

If you need to break down the number by categories or over time, use a bar or line chart instead.
