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.

Each trace has its own actions menu: move it to another axis, change its color, or remove it. On an existing trend, adding or removing traces, changing a trace color, and adding, removing, or editing an axis all save automatically. While building a brand-new trend, these changes are held 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), add another axis from the actions menu at the top of the trace panel.

Axis Configuration

Each axis header has an actions menu. Renaming, the side of the chart the axis sits on, its color, and deleting it are all in that menu; the scale limits open from 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

Clearing the limits from the menu returns the axis to fitting its own data.

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. Traces in each group share that axis's scale. Reassign a trace from its actions menu, or drag it between groups.

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