Bar Chart

Bar Chart

A bar chart compares values across categories. Each chart.Series becomes one group of bars, and the X labels of its data points become the categories. Bars can be stacked, laid out horizontally and annotated with markers.

Bar Chart

func view(wnd core.Window) core.View {
    series := []chart.Series{
        {
            Label: "Online",
            DataPoints: []chart.DataPoint{
                {X: "Q1", Y: 120}, {X: "Q2", Y: 180}, {X: "Q3", Y: 150}, {X: "Q4", Y: 210},
            },
        },
        {
            Label: "Retail",
            DataPoints: []chart.DataPoint{
                {X: "Q1", Y: 90}, {X: "Q2", Y: 110}, {X: "Q3", Y: 130}, {X: "Q4", Y: 160},
            },
        },
    }

    return barchart.BarChart(chart.Chart{
        Frame:      Frame{}.Size(L560, L320),
        XAxisTitle: "Quarter",
        YAxisTitle: "Orders",
    }).Series(series)
}
