4.2.8 Status History

4.2.8.1 Overview

The Status History panel displays a grid of colored cells where each column represents a time bucket and each row represents a metric. It provides a compact, calendar-style view of state patterns across multiple dimensions simultaneously — ideal for spotting recurring patterns, shifts, or periods of abnormal behavior across a long time range.

The screenshot shows Current (A) and Voltage (V) displayed side by side, with each column representing one time bucket colored according to the configured color scheme or threshold rules.

4.2.8.2 When to Use

Use the Status History panel when:

• You want a high-level calendar-style overview of states across many time buckets (hours, days, shifts)
• You are comparing state patterns across multiple metrics or devices at the same time
• You need to answer questions like "which hours this week had out-of-limit conditions?" or "which devices were in alarm on Monday?"

For a continuous band showing every state transition in detail, use the State Timeline instead.

4.2.8.3 Configuration

Graph Settings

Graph settings control the appearance of the grid cells:

Setting	Description
Show Values	Whether to display a value label inside each cell: Auto, Always, Never
Border Width	Width of the border between cells (0–10)
Row Height	Relative height of each row (0–1)
Column Width	Relative width of each time-bucket column (0–1)
Fill Opacity	Transparency of the cell fill color (0–1)

The time bucket size is controlled by the Sliding Window setting in the data configuration. For example, a 1-hour sliding window produces one column per hour.

Axis

The Status History panel configures only the X axis:

Setting	Description
X Axis	Show or hide the X axis
X Axis Time Format	Display format for X axis timestamps. Available when X axis is shown
Rotate Labels	Rotation angle for X axis time labels, -90° to +90°
Label Interval	Density of X axis labels: Auto, Small, Medium, Large
Show Grid Lines	Whether to display X axis grid lines: Auto, On, Off

Tooltip

When hovering over a cell, the tooltip shows the time bucket's timestamp and the metric value:

Setting	Description
Tooltip Mode	Display mode on hover: Single (hovered metric only) or Hidden
Max Width	Maximum tooltip width in pixels

Standard Options

Setting	Description
Min	Lower bound for values. Leave blank to auto-calculate from data
Max	Upper bound for values. Leave blank to auto-calculate from data
Decimals	Number of decimal places to display. Leave blank for auto
Color Scheme	How series colors are assigned: Single Color, Shades of Color (by series), From Thresholds (by value), Classic Palette, Classic Palette (by series name), or Custom Palette

Data Links

Data links attach clickable URLs to cells:

Setting	Description
Title	Display name for the link
URL	Target URL, supports variable interpolation
Open in New Tab	Whether to open the link in a new browser tab
One-Click	When enabled, clicking a cell immediately navigates to the URL. Only one link per panel can have this enabled

Value Mappings

Value Mappings replace raw data values with custom display text and colors — this is the primary way to configure how states appear in the grid. The screenshot shows the range [246–250] mapped to an orange-red "HIGH" label:

Click Edit Value Mappings to open the mapping dialog, where you select a mapping type and configure the condition, display text, and color:

Mapping Type	Description
Value	Exact match on a specific value or text string
Range	Match a numeric range
Regex	Match using a regular expression and replace with substituted text
Special	Match null, NaN, booleans, empty strings, and other special cases
Others	Match all values not covered by the preceding rules

Color Thresholds

Color Thresholds define numeric ranges and their associated colors, making them suitable for continuous metrics like voltage or temperature. The Color Scheme must be set to From Thresholds (by value) for thresholds to take effect:

The screenshot configures a threshold of 245 (pink) and a Base (blue). Time buckets where voltage exceeds 245 V are shown in pink; all others are shown in blue.

Setting	Description
Add Threshold	Add a threshold rule consisting of a numeric boundary and a color

Overrides

Overrides let you apply style settings to individual metrics, overriding the global graph configuration for that metric only. Select a metric by name, then add the properties to override. Supported properties include: Series Style, Line Width, Fill Opacity, Line Opacity, Line Color, Point Size, Show Points, Connect Nulls, Stack, Gradient Mode, Show Values.

Downsampling

When query results contain too many data points, downsampling reduces the number of rendered points to improve display performance:

Setting	Description
Enable Downsampling	Toggle. Disabled by default
Max Data Points	Maximum number of data points retained after downsampling
Aggregation Function	Aggregation method applied during downsampling, such as AVG, MAX, or MIN

Scheduled Report

The Status History panel supports scheduled reports, which periodically deliver the chart as an image to a specified email or Feishu group. Access the configuration from the panel's top-right menu.

4.2.8.4 Example Scenarios

Weekly alarm heatmap. Ten alarm signals are added as rows with a 1-hour sliding window, producing 168 columns (one per hour over 7 days). Value mappings set 0 → gray and 1 → red. The resulting grid shows at a glance which devices were in alarm at which hours throughout the week.

Shift-by-shift operating mode review. An 8-hour sliding window across a month produces one column per shift. Each row represents a production line's operating mode. The operations manager can immediately see which shifts ran in the expected mode and which had unplanned stoppages.

Out-of-limit condition calendar. A quality engineer adds 12 process variables as rows with a 1-day sliding window. Value mappings color cells green (in-limit) or red (out-of-limit). The resulting calendar view highlights which days had quality issues across the process.

Use the Status History panel when:

• You want a high-level calendar-style overview of states across many time buckets (hours, days, shifts)
• You are comparing state patterns across multiple metrics or devices at the same time
• You need to answer questions like "which hours this week had out-of-limit conditions?" or "which devices were in alarm on Monday?"

For a continuous band showing every state transition in detail, use the State Timeline instead.
