BigBoard — Critical Infrastructure Intelligence

Time & zoom

Pick a preset window, or drag across the graph to zoom into any span. Custom opens a start/end picker.

1h – AllPreset look-back windows. If the window is empty on open, it widens automatically until data appears.

CustomChoose an exact start and end, or a preset like Today / This week.

Drag to zoomClick-drag across the plot to zoom; Reset zoom returns to the window.

Log timeCompress the time axis logarithmically to see recent detail alongside older history.

Live

● LiveFollow now: stream new samples over the selected range. Available on relative ranges only (not Custom or All).

Y-axis scale

LinearValues as-is.

SqrtSquare-root scale — eases moderate skew.

LogLogarithmic — spans many orders of magnitude.

±LogSymmetric log for series that cross zero.

AsinhLog-like but defined through zero and for negatives.

Transforms

%Rescale to percent of the window's range.

ZZ-score — standard deviations from the mean.

ΔPoint-to-point change (delta).

RateChange per second between samples.

Series & overlays

Min / Max / AvgToggle each aggregate line on or off.

Fit avgScale the axis to the average line so small variation is readable.

↗ TrendLinear-regression trend line (linear time mode only).

⚠ AnomaliesFlag points beyond a Z-score threshold as outliers.

Standard deviation

Separate axisPlot σ on its own axis.

σ BandsShade ±1σ around the average.

Heat lineColor the average line by local variance.

CV %Coefficient of variation — σ as a percent of the mean.

Save & export

Save imageSave a picture of exactly what is on screen — the title, unit, time range, the four figures and the BigBoard build stamp are printed on it.

Export CSVDownload the raw data points as CSV, freshly read. Export CSV writes the last fetched window; a gap in the data stays an empty cell, never a filled-in number.

Compare side by side

One metric shows at a time here. To compare several, move them to a Board:

1 · ClipboardClick + Clipboard to add this metric to the clipboard dock. Repeat from any other graph for each metric or device you want beside it.

2 · BoardsOn Boards, the dock offers ⬇ Place as N panels and ▦ Combine into 1 chart — or drag a chip onto a slot.

3 · ArrangeSwitch a chart's Stat / Gauge / Line view, or split a combined chart back apart.

4 · LayoutPick a split layout so they sit side by side. Save Layout keeps the comparison for next time.
