Mixed Chart Examples

With Chart.js, it is possible to create mixed charts that are a combination of two or more different chart types. A common example is a bar chart that also includes a line dataset.

Basic Usage

Source

<RzChart Configure=@(c => c
    .Data(d => d
        .Labels("January", "February", "March", "April")
        .Datasets(ds => {
            ds.Bar()
              .Label("Bar Dataset")
              .Data(10, 20, 30, 40)
              .BackgroundColor("var(--chart-1)")
              .BorderColor("var(--chart-1)");

            ds.Line()
              .Label("Line Dataset")
              .Data(50, 40, 45, 50)
              .BorderColor("var(--chart-2)")
              .BackgroundColor("var(--chart-2)");
        })
    )
    .Options(o => o
        .Responsive(true)
        .MaintainAspectRatio(false)
        .Plugins(p => p.Title(t => t.Display(true).Text("Chart.js Mixed Chart")))
    )) />

By default, datasets are drawn such that the first one is top-most. This can be altered by specifying order option to datasets. order defaults to 0. Note that this also affects stacking, legend, and tooltip. So it's essentially the same as reordering the datasets.

The order property behaves like a weight instead of a specific order, so the higher the number, the sooner that dataset is drawn on the canvas and thus other datasets with a lower order number will get drawn over it.
