What it is¶
The Number Chart is a single aggregate value with no dimensions. For
example, in the image above, the value is the average of an entire column
named Amount. You can aggregate Number charts by
Count Unique (for
Custom (where you can apply any SQL compatible custom
function; see Custom Measures).
When to use it¶
Use a number chart when you want a compact display of one
metric and are not interested in breaking out that metric by time,
category, or some other dimension. You can add multiple number charts
to a dashboard to concurrently view several aggregate calculations. For
example, viewing the
Sum of a
column all at once.
How to set it up¶
Since the Number Chart has no dimension, specify the column to be aggregated, and choose the aggregation type.
