Traces & Axes

Each tag added to a trend becomes a trace — a colored line on the chart. The trace panel on the right side of the detail page manages which tags are plotted and how they are scaled.

Adding & Removing Traces

Use the tag search at the top of the trace panel to find and add tags. Each new trace is automatically assigned a color from a 10-color palette. Click a trace's color swatch to change it using preset swatches or a full color picker.

Remove a trace by clicking the trash icon. Changes are not persisted until you click Save.

Model-managed traces are locked

Traces on a model-managed trend show a lock icon and cannot be removed — they are synchronized from the model's bindings.

Multiple Y-Axes

By default, all traces share a single Y-axis. If your tags have different scales (e.g. temperature in degrees and pressure in PSI), click Add Y-Axis to create additional axes.

Axis Configuration

Click the edit icon on an axis header to configure it:

Setting	Description	Default
Label	Display name shown on the chart	Axis 1, Axis 2, etc.
Position	Left or Right side of the chart	Left
Min / Max	Hard limits — the axis never exceeds these bounds	Auto
Suggested Min / Max	Soft limits — preferred range, but the axis expands if data requires it	Auto
Color	Custom color for the axis title and tick labels	Theme default

Hard vs suggested limits

Use Min/Max to fix the range (e.g. 0–100 for a percentage). Use Suggested Min/Max when you want a preferred range that can still expand for outliers.

Assigning Traces to Axes

With two or more axes, the trace panel switches to a grouped view. Drag traces between axis groups to reassign them. Traces in each group share that axis's scale.

The left axis displays grid lines; right axes show ticks and labels only. Each axis is color-coded to match its traces.
