Number Chart
A number chart displays one or more numbers, optionally with the delta to another (e.g. previous) value.

Data Requirements
The Number chart is available if the query result has one or two rows of data, each
with 1-8 numerical columns. The values in the first row are interpreted as the
"current" values and the values in the (optional) second row are interpreted as the "previous"
values. For example, a query result such as
| a | b |
|---|---|
| 3 | 42 |
| 5 | 43 |
produces the following number chart (with default configuration)

Interactive Features
When hovering with the cursor over a number chart, the current and previous value (if present) are shown in a tooltip. The labels used in the tooltip can originate from another result column, see Configuration.

If configured with a drill-down, clicking on the current value or the delta can result in settings a filter value on the same or a different dashboard.
Links
A value can be displayed as a clickable link by formatting its column as HTML and returning an anchor tag from your query — useful for linking a metric to a related dashboard, record or external page.

For example, setting a column's format to HTML (see Settings)
and returning
'<a href="https://example.com/dashboard" target="_blank" rel="noopener noreferrer">Open dashboard</a>'
renders Open dashboard as a link that opens in a new tab. The markup is
rendered exactly as written, so include attributes such as target="_blank" and
rel="noopener noreferrer" yourself — the
Table chart adds these automatically
when it detects links in Text columns.
Configuration
The Number chart configuration has the following general options:

- S, M, L, XL: Preset sizes for the numbers shown.
- Horizontal, Vertical: If multiple numbers (i.e. multiple rows) are shown, they can be either horizontally or vertically aligned.
- Classic, Modern: Display style for the chart (see Display Style).
- Chart Alignment: Whether the entire chart should be left-aligned, centered or right-aligned.
- Display Title: Whether the column names should be shown as titles above the numbers.
- Human Column Titles: Whether the titles, if shown, should use human-friendly capitalization.
Display Style
The Number chart supports two display styles:
- Classic: The original styling, used by all existing charts. Delta colors use the dashboard color scheme, and drill-down hover uses a box-shadow underline effect.
- Modern: Updated typography with bolder values, lighter titles, and smaller delta
text. Delta colors use more prominent green (
#34A853) and red (#DB4437). Drill-down hover uses a subtle scale animation with a text-decoration underline.
All newly created Number charts default to the Modern style. Existing charts are unaffected and remain in Classic style unless manually switched.
Settings
In the Settings section the formatting of the
numeric columns (and deltas, if a previous value exists) is configured. Note
that you can choose to hide result columns that are not intended to be shown but
e.g. used in a drill-down or conditional
formatting.

If a result column that is hidden (by choosing the - option), the Use label as tooltip option is available. If enabled, the values of that column are used
as the tooltip labels rather than the default labels Current value and
Previous value.
Drill-Down
A drill-down action on a number chart can be used to apply a value (typically the shown number, but any result column can be used) as a filter value on the same or a different dashboard when selected, thus making the number chart an interactive filter control.

Conditional Formatting
The Conditional Format section allows configuring formatting rules for the
numbers shown based on conditions on any result column.
