Normalize & stacked views
Change how TimeView displays multiple series - as a combined stack, a proportional breakdown, or a normalized 0–100% comparison.

Overview
By default, TimeView shows each series on its own scale as independent lines or bars (Normal view). You can switch to a different view when you want to understand how devices contribute to a total, or compare patterns across devices with very different consumption levels.
There are four options - three chart types and one data-display toggle - all in the Customize chart panel:
- Normal - default; each series independent.
- Stacked - series stacked on top of each other; total height = combined consumption.
- Stacked % - each series shown as its share of the total at every point in time.
- Normalize data - scales every series independently to a 0–100% range, so you can compare shapes regardless of unit or magnitude.
Note: Stacked, Stacked %, and Normalize data require the Optimize package. Normal is available to all users.
How to Open the Chart Type Controls
Click the gear icon (⚙) in the top-right toolbar to open the Customize chart panel. Make sure the Chart tab is selected.
- Chart type - the Normal / Stacked / Stacked % selector at the top of the panel.
- Normalize data - a checkbox under Data display, just below Chart type.
Changes apply to the chart immediately. The panel stays open so you can switch between views.
Chart Types: Normal, Stacked & Stacked %
Normal
The default view. Each series is drawn independently with its own Y-axis scale. Use Normal when you want to see absolute values for each device without aggregation.
Stacked
In Stacked view, all eligible series are layered on top of each other. The height of the combined shape at any point equals the sum of all visible series.
A blue info banner appears at the top of the chart: "Series are summed and stacked; the height shows the total."
When you hover over the chart, the tooltip shows each series with its absolute value and its percentage contribution to the total at that moment. The total is shown at the bottom of the tooltip.
Use Stacked when you want to:
- See total consumption across multiple devices at a glance.
- Identify which device is the largest contributor to a peak.
- Understand how the load is composed over time.
Stacked %
In Stacked % view, the Y-axis runs from 0% to 100%. At every point in time, each series is shown as its share of the total - the areas always fill the full height of the chart.
The tooltip shows percentage values for each series; the total row shows 100%.
Use Stacked % when you want to:
- See how the composition of your load changes over time (for example, does HVAC dominate on hot days?).
- Compare relative contribution regardless of the absolute consumption level.
Normalize Data
Normalize data is a separate option from the chart type. It scales every line series independently to a 0–100% range based on each series' own minimum and maximum within the selected time period. The absolute values are replaced by relative position within each series' own range.
When Normalize data is active, a banner appears above the chart: "Normalized View (0–100%) - Scaled for easier comparison"
The hover tooltip shows both the normalized percentage and the actual absolute value in parentheses - for example, Mains · 12.4% (63.2 kW).
Use Normalize data when you want to:
- Compare the shape of consumption patterns across devices with very different scales - for example, a large main feed (1,500 kW) and a small circuit (5 kW) on the same chart.
- Identify whether two devices follow the same pattern regardless of magnitude.
- Compare across different measurement types (for example, Power and Current) without unit conversion.
Normalize data and Stacked are mutually exclusive
You cannot use Normalize data at the same time as Stacked or Stacked %. When either Stacked view is active, the Normalize data checkbox is greyed out with the message "Turn off Stacked or Stacked % to normalize data." Switch back to Normal chart type first, then enable Normalize data.
Choosing the Right View
| I want to… | Use |
|---|---|
| See absolute values for each device separately | Normal |
| See total consumption and each device's share of it | Stacked |
| See each device as a % of the total at every moment | Stacked % |
| Compare consumption patterns across devices regardless of scale | Normalize data |
| Compare a 1,500 kW main with a 5 kW sub-circuit side by side | Normalize data |
Things to Know
Non-stackable measurement types. Current (A), Voltage (V), Frequency (Hz), Power Factor, Flow, and State cannot be stacked because they are instantaneous readings rather than cumulative values. When you switch to Stacked or Stacked %, series of these types are dimmed in the legend with a tooltip explaining why. They remain on the chart but are excluded from the stack calculation and the tooltip total. You can still toggle them on or off from the legend.
Single series selected. The Stacked and Stacked % options are disabled when only one series is on the chart. A tooltip reads "Select more than one series to enable stacking."
Legend order in Stacked view. Series are stacked with the largest contributor at the bottom and the smallest at the top. This order is calculated once for the visible time range and stays stable as you pan or zoom.
Hiding a series. If you hide a series using the eye icon in the legend, it is removed from the stack calculation and the tooltip total. In Stacked % view, the remaining percentages renormalize automatically to sum to 100%.
