Types

type Model 

type Model struct {
	linechart.Model
	// contains filtered or unexported fields
}

Model contains state of a timeserieslinechart with an embedded linechart.Model The X axis contains time.Time values and the Y axis contains float64 values. A data set consists of a sequence TimePoints in chronological order. If multiple TimePoints map to the same column, then average value the time points will be used as the Y value of the column. The X axis contains a time range and the Y axis contains a numeric value range. Uses linechart Model UpdateHandler() for processing keyboard and mouse messages.

func New
