Linear Gauge Flow

This flow covers the 6 steps for the horizontal or vertical progress bar — the Linear Gauge. Step 4 is the dedicated Linear Gauge Axis Design screen where orientation, axis range, bar/marker pointer, and range bands are configured. Steps 5, 6, and 7 are skipped.

Chart Types Using This Flow

Chart Type	Primary Use	Page
Linear Gauge	Horizontal/vertical progress bar, target visualization	Linear Gauge

Radial Gauge Is a Separate Flow

Radial Gauge uses a different Axis Design screen for the circular pointer gauge. → Radial Gauge Flow

Step Pages

This flow runs 6 of the wizard steps (5, 6, and 7 are not present):

#	Step	Page	Key Content
1	Group Selection	01 — Group Selection	Select the Gauge card
2	Chart Type Selection	02 — Chart Type	Linear Gauge card
3	Compass Record Selection	03 — Compass Record	Single row, single numeric value
4	Linear Gauge Axis Design	04 — Linear Axis Design	Orientation, range, bar/marker pointer, range bands, value source
8	Card Design	08 — Card Design	Refresh, Border, Info Card
9	Display Information	09 — Display Info	Name, Tags, Folder

Steps Not in This Flow

Skipped Step	Purpose in the standard flow	Why it isn't needed here
5 — Series Design	Color, marker, and data label settings for line/bar series	The gauge shows a single instantaneous value; there is no "series" concept
6 — Add Series	Add a second/third series to the chart	The gauge does not support multiple series
7 — General Design	Title, legend, tooltip, axis, zoom settings	All visual settings (orientation, bar/marker pointer, range bands, labels) are consolidated in Step 4 — Axis Design

Data Requirements

The Linear Gauge query must return a single row with a single numeric value.

SELECT tank_fill_percent
FROM tank_status
WHERE tank_id = 1
ORDER BY ts DESC
LIMIT 1;

Column	Type	Role
Value column	NUMERIC	Instantaneous value displayed on the linear gauge
