Plot Pane

A rich multi-series time-series charting pane for quantitative analysis. Each series is independently configured with its own plot type, data source, styling, and statistical overlays. The Plot pane supports dual Y-axes, threshold lines, vertical event markers, and both live and historical data backends.

SeriesConfig

Field	Description
source_id	Data source identifier (layer or ClickHouse query)
x / y fields	Dot-path to the X and Y axis values in the data
color	Series color (hex or named)
plot_type	Scatter, Line, Area, or Histogram
line_style	Solid, Dashed, or Dotted
marker_shape	Point marker shape for Scatter and Line modes
smoothing_window	Rolling average window size for noise reduction
aggregate	Mean, Sum, Min, Max, or Count
normalize	MinMax, ZScore, or Percent normalization
show_trend_line	Overlay a linear regression trend line
show_std_bands	Display standard deviation bands around the series
secondary_axis	Plot this series on the right Y-axis
histogram_bins	Number of bins when plot_type is Histogram

Data Sources

LayerStore (Live): Stream real-time entity snapshots for live charting
ClickHouse (Historical): Query archived data for long-range analysis

View Modes and Annotations

Free: Manual pan and zoom on both axes
Fit: Auto-fit all data into the visible area
Follow: Sliding window that tracks the latest data in real time
Thresholds: Horizontal lines at critical values (e.g. alarm limits)
VLines: Vertical event markers for incidents or state changes
Config Panel: Per-series configuration accessible from the plot toolbar

Keyboard Shortcuts
