Live Line Chart
A trend that keeps moving while you watch it. A live line chart is a line chart on a sliding time window: new points arrive at the right, the oldest scroll off the left, and the axis re-scales as it goes.
Live Line Chart streams a sliding window of the most recent readings; the seed window is 12, 14, 13, 15, 18, 17, 16, 19, 22, 21, 20, 23, 26, 24, 23, 25, 28, 27, 26, 29.
What is a live line chart?
A live line chart is a line chart on a sliding time window: new points arrive at the right, the oldest scroll off the left, and the axis re-scales as it goes.
Why is a live line chart useful?
Some signals are only meaningful while they are happening. A support queue spiking, an integration sync failing, sessions dropping off after a release - these need to be visible now, not in tomorrow's report.
How RetainCLM uses it
Watch scoring throughput while a large customer import is running, so a stalled pipeline shows up as a flat line rather than as a silence.
The chart above is drawn from illustrative demo data chosen to make the visualization legible. It does not describe real RetainCLM customers. On a live account the same chart is drawn from your own customer, usage, billing and support data.
How to read it
Judge the recent window, not the whole line. On a sliding axis the left edge is whatever happened to still be in the buffer, so cross-window comparison is unsafe.
Limitations to keep in mind
Live charts invite over-reaction to noise. Pair one with a stated baseline or threshold, or people will read every ordinary fluctuation as an incident.

A live line chart is most useful alongside customer intelligence, the full visualization library. RetainCLM builds these views on one unified customer record, so a pattern you notice in one visualization can be followed into the next without exporting anything.
Questions about the live line chart
What is a live line chart?
A line chart that updates continuously on a fixed-width sliding time window, used for monitoring a signal in real time rather than analysing a fixed period.
When should a dashboard use live charts?
Only for measures someone would act on within minutes. Everything else is better served by a stable time range that can be compared across sessions.
