X(Func<T, double>)

Sets the function that extracts the X-axis value from each data item.

Parameters:

• selector (Func<<T>, Double>):

Returns: ScatterChartWidget`1

public ScatterChartWidget<T> X(Func<T, double> selector)

XRange(double, double)

Sets the explicit X-axis range.

Parameters:

• min (Double):
• max (Double):

Returns: ScatterChartWidget`1

public ScatterChartWidget<T> XRange(double min, double max)

Y(Func<T, double>)

Sets the function that extracts the Y-axis value from each data item.

Parameters:

• selector (Func<<T>, Double>):

Returns: ScatterChartWidget`1

public ScatterChartWidget<T> Y(Func<T, double> selector)

public ScatterChartWidget<T> YRange(double min, double max)

Remarks

Points are NOT connected by lines. Each data point plots a single braille dot. Multiple series can be created via to color-code groups.

Examples

Create a scatter chart with grouped series:

var app = new Hex1bApp(ctx =>
    ctx.ScatterChart(data)
        .X(d => d.Height)
        .Y(d => d.Weight)
        .GroupBy(d => d.Category)
        .Title("Height vs Weight")
);
