What is the Internet, if not the world's most efficient way to say something bad about someone -- and post pictures of cats?

The ASP.NET Chart helper displays charts, as you can read in the chapter Displaying Data in a Chart:


For purposes of the Chart helper, you specify the chart type (bar, line, area, etc.) by passing the chartType parameter to the AddSeries method:

@{ 
var key = new Chart(width: 600, height: 400)
.AddTitle("Chart Title")
.AddSeries(
chartType: "Pie",
name: "Employee",
xValue: new[] { "Peter", "Andrew", "Julie", "Mary", "Dave" },
yValues: new[] { "2", "6", "4", "5", "3" })
.Write();
}
But this is just a string, so it's not clear what-all you can pass for the chartType value. Unless you happen to know that the Chart helper is actually a wrapper around the ASP.NET Chart control. If you know that, you can find the documentation for that dude (it's in a downloadable .chm file)[1] and learn that SeriesChartType enumeration supports the following:

Area
Bar
BoxPlot
Bubble
Candlestick
Column
Doughnut
ErrorBar
FastLine
FastPoint
Funnel
Kagi
Line
Pie
Point
PointAndFigure
Polar
Pyramid
Radar
Range
RangeBar
RangeColumn
Renko
Spline
SplineArea
SplineRange
StackedArea
StackedArea100
StackedBar
StackedBar100
StackedColumn
StackedColumn100
StepLine
Stock
ThreeLineBreak

I haven't tried all of them, but basically this is the list of names that you can pass, as strings, to the Chart helper in a Razor page. Actually sorting out what all these chart types are for and how they relate to your data series is, for the time being, left as an exercise for the reader.
