Apache ECharts gallery¶

How the examples of the Apache ECharts gallery (about 300, ECharts 6.1) map to New-UDEChart. The module bundles all of Apache ECharts, so every series type and option is available through -Options; the parameters cover what is needed often.

Parameter: a parameter of New-UDEChart does it.
-Options: possible with -Options on top of a chart type; tested means a showcase chart uses it.
Server side: done in PowerShell before the data reaches the chart.
Not included: needs something the module does not ship, or does not fit an app; the reason is given.

linear regression	Parameter: `-Trend Linear` (with `-Forecast`, `-TrendTarget`)
exponential, logarithmic, polynomial regression, clustering	Server side: compute in PowerShell and pass the fitted line as a series; not built in

histogram	Parameter: `-Type histogram`, `-Bins`
candlestick with volume, brush, large	Parameter: `-Type candlestick`, `-Volume`
OHLC bars (custom-ohlc), error bars (custom-error-bar)	Not included: custom series need a JavaScript `renderItem` function, which PowerShell cannot send

Heatmap and calendar¶

Gallery	How
cartesian heatmap, large heatmap, piecewise colours	Parameter: `-Type heatmap`; piecewise via -Options (`visualMap`)
correlation and confusion matrix (matrix-correlation-heatmap, matrix-confusion)	Parameter: `-Type heatmap`

Maps and geo¶

map, geo, lines (flight routes) and everything with bmap are not included: a map needs its GeoJSON or SVG registered in the browser with echarts.registerMap, which the module does not ship and PowerShell cannot call; bmap needs the Baidu Maps API online. A parameter that takes GeoJSON from PowerShell (sites, data centres, customers per country) is a possible extension.

3D, globe, GL¶

Not included: they need the separate echarts-gl package, and they rarely help to read operational data.

Data handling (dataset, transform)¶
