What Is the Chart Series Add-ons Panel?
The Chart series add-ons panel lets you extend a single device's chart series with extra information - statistical reference lines, signal-quality overlays, data-quality markers, or an entirely different metric - without changing what the rest of the chart shows.
Everything in the panel is per device. Add-ons you enable for one device have no effect on the other devices on the chart.
Your add-on selections are saved automatically as part of your active view. If you save a preset, the configuration is saved with it and restored when you load the preset again.
How to Open the Panel
- Add at least one device to the chart using the device tree on the left.
- In the legend on the right, hover over any device row. A small add-ons icon (stacked layers) appears at the right of the row, with the tooltip "Add chart series add-ons".
- Click the icon. The Chart series add-ons panel opens, scoped to that device. The device name appears in the panel header next to the title.
The panel has three sections side by side:
- Category rail (left) - four categories: Statistics, Quality, Thresholds, and Overrides.
- Items list (center) - the available add-ons for the selected category. Check the box next to any item to enable it immediately on the chart.
- Detail card (right) - a description, unit, chart display preview, and formula (where applicable) for whichever item you are hovering over. Before you hover anything, the card reads "Hover over an add-on to see details."
Use the Search add-ons field at the top of the panel to find a specific option across all categories at once.
To close the panel, click × in the top-right corner of the panel or press Esc.
Statistics
Available for: All devices and measurement types Package: Optimize
The Statistics category adds reference lines and bands derived from the selected device's data in the currently selected time range. You can enable any combination at the same time.
| Statistic | What it shows | How it appears on the chart |
|---|---|---|
| Average | Arithmetic mean of all samples in the range | Dashed horizontal line |
| Median | Middle value of all sorted samples | Dashed horizontal line |
| Minimum | Lowest recorded value | Dashed horizontal line |
| Maximum | Highest recorded value | Dashed horizontal line |
| Absolute change | Last value minus first value | Dashed horizontal line |
| Percent change | (Last − First) / First × 100 | Dashed horizontal line |
| Percentile range (P10–P90) | The band spanning the 10th to 90th percentile | Shaded band |
Each enabled statistic is scoped to the device it belongs to.
Before you enable anything, hover any item in the list. The detail card on the right fills in automatically with a plain-language description of what that statistic measures, the chart display type (for example, Dashed horizontal line), and the mathematical formula. You can read through every option this way without committing to any of them. The same hover-to-preview behaviour works in every category - Quality, Thresholds, and Overrides - so you always know what you're enabling before you check the box.
Statistics recompute automatically whenever the time range changes. If Percent change cannot be calculated because the first value is zero, the legend shows Percent change · N/A and the line is omitted from the chart.
To disable all statistics for a device at once, click Clear in the Statistics category header.
Note: Statistics require the Optimize package. If the items appear locked, contact your administrator.
Quality: Signal Overlays and Data Corrections
The Quality category groups two kinds of optional additions: signal overlays (extra data series about the sensor or the electrical signal) and data-quality markers (visual flags on corrected data points).
Signal Quality (RSSI)
RSSI (Received Signal Strength Indicator) overlays the sensor's wireless signal strength as a dotted line, measured in dBm, on a secondary right-side Y-axis.
Enabling RSSI helps you diagnose data gaps. If you see missing or irregular readings in a device's series, the RSSI overlay lets you check whether the gaps coincide with periods of weak connectivity.
Availability: All Panoramic sensors; line chart types only; periods shorter than one year; not available for pulse meters.
Enable RSSI in the Quality category. The dotted line appears immediately, scoped to that device, without replacing the primary series.
Note: RSSI introduces a second Y-axis. You can have at most two Y-axes on the chart at any time. Enabling a third unit type blocks with a warning until you disable one of the existing unit-bearing items.
Bulk (Manual Correction) and Auto Correction
Data correction markers flag individual data points where the recorded value has been adjusted - either by an operator or automatically by the system.
Available for: All devices
| Marker | What it indicates |
|---|---|
| Bulk | A marker on a data point that was manually corrected by an operator - for example, a gap that was filled in or a reading that was adjusted by hand. |
| Auto correction | A marker on a data point that the system corrected automatically - for example, a reading estimated to fill a gap or fix an irregular value. |
Both can be enabled at the same time. They overlay the existing series without adding new lines or Y-axes.
Use these markers when reviewing historical data before making decisions or exporting - they help you see at a glance which readings were measured versus corrected.
Coming Soon: THD and Sag & Swell Events
THD (Total Harmonic Distortion) and Sag & Swell events appear in the Quality category for PAN-42 sensors, but are not yet active. Both show a Soon label and their checkboxes are disabled. They will be enabled in a future release.
You can hover these items to read what they measure and how they will appear on the chart.
Thresholds (Coming Soon)
The Thresholds category is visible in the panel but is not yet active - it shows a Coming soon label. Threshold configuration will be available in a future release.
Overrides: Show a Different Metric for One Device
The Overrides category lets you add a different measurement type to one device's series while the rest of the chart continues showing the global metric.
When would you use this?
You might be charting three devices on Power (kW), but want to check one device's Current (A) at the same time- for example, to understand whether a power spike is from a current increase. Enabling Current as an override for that one device adds a Current line to its series only. The other devices continue showing Power.
How overrides work:
Open the Overrides category for the device you want to customize. The list shows:
- The main metric - whichever measurement type you currently have selected in Show By - at the top of the list, pre-checked and labeled Main metric. You cannot uncheck it from this panel. Switch Show By to a different metric and the main metric row updates to match; the previous one becomes a toggleable override.
- All other available metrics for that device type, as toggleable rows. Enabling any of them adds that metric as an extra series for this device only.
The panel shows a note: "Add up to 2 for optimal chart visualization." Adding an override with a different unit (for example, Current (A) alongside Power (kW)) introduces a secondary right-side Y-axis. You can have at most two Y-axes on the chart at any time. A warning blocks a third.
Each override series appears as a separate row in the legend, labeled with the device name and the metric- for example, Generation · Power and Generation · Current.
Available overrides by device type:
Panoramic sensors - the full list in the order the panel shows them:
| Override | Label | Notes |
|---|---|---|
| (Your active Show By metric) | Main metric | Pre-checked and disabled. Whichever metric you selected in Show By- Power, Energy, Current, etc. - appears here as the main metric and cannot be unchecked from this panel. |
| Apparent power | Computed | PAN-42 only. The total power drawn by the load, combining active and reactive power. Computed as √(P² + Q²); the legend labels it Computed to distinguish it from a directly measured value. |
| Power factor (PF) | — | PAN-42 only. The ratio of active power to apparent power. A value near 1.0 means the load is using power efficiently. |
| Reactive power (kVAr) | — | PAN-42 only. Power that circulates between source and load without doing useful work. High reactive power relative to active power signals efficiency losses. |
| Power | — | All Panoramic sensors (appears as an override option when Power is not already the main metric) |
| Energy | — | All Panoramic sensors |
| Current | — | All Panoramic sensors |
| Cost | — | All Panoramic sensors; requires a utility tariff configured |
| Voltage | Pan-42 only | PAN-42 sensors only |
| Carbon | — | All Panoramic sensors; requires a carbon factor configured |
External meters: Flow, Volume, Power, Energy, Cost, State.
Notes:
- Apparent Power, Power Factor, and Reactive Power only appear in the Overrides list when the selected device is a PAN-42 sensor. On non-PAN-42 devices, these rows are not shown.
- Voltage is shown for all Panoramic sensors but is greyed out with a Pan-42 only chip when the device is not a PAN-42.
