Bar Chart
Bars over a category axis, horizontal or stacked. The default choice for comparing discrete categories — output per line, downtime by reason, scrap by shift.
Historian
The full historical trend chart. It loads the time range you configure and then keeps updating as new readings arrive, so one chart answers both "what happened last Tuesday" and "what is happening now".
HMI Sparkline
A small inline trend with an optional desired-range band, light enough to repeat many times on one view — one beside every value in a table of forty tags.
HMI Trend
A high-performance-HMI embedded trend: the Y-axis is the operating range, a band shows the desired range, dashed lines mark the alarm limits, and the trace stays neutral until it leaves the desired band. An operator reads deviation at a glance without reading numbers.
Line Chart
Line series over a category axis, with smooth / step / area / stack toggles. Bind it to a named query — this is for query results, not for tag history (use **Historian** for that).
Pie Chart
Proportions of a whole, as a pie, donut (set `innerRadius`) or rose. Useful for a handful of categories that genuinely sum to something meaningful.
Radar Chart
A multi-axis radar, one polygon per row, with numeric columns becoming axes. Good for comparing a few entities across the same handful of measures.
Scatter Chart
Scatter and bubble plots, with optional size and grouping fields. The right tool when you are looking for a relationship between two variables rather than a trend over time.
Sparkline
A compact, chrome-less trend — line, area or bar — bound to a named query or a tag history. No axes, no legend, no grid: just the shape of the recent past.
