示例1: Plot
func (pt *Dots) Plot(da plot.DrawArea, plt *plot.Plot) {
trX, trY := plt.Transforms(&da)
da.SetColor(pt.Color)
for i := range pt.Y {
// Transform the data x, y coordinate of this bubble
// to the corresponding drawing coordinate.
x := trX(pt.X[i])
y := trY(pt.Y[i])
// Get the radius of this bubble. The radius
// is specified in drawing units (i.e., its size
// is given as the final size at which it will
// be drawn) so it does not need to be transformed.
rad := vg.Length(2)
// Fill a circle centered at x,y on the draw area.
var p vg.Path
p.Move(x+rad, y)
p.Arc(x, y, rad, 0, 2*math.Pi)
p.Close()
da.Fill(p)
}
}示例2: Plot
// Plot implements the Plot method of the plot.Plotter interface.
func (bs *Bubbles) Plot(da plot.DrawArea, plt *plot.Plot) {
trX, trY := plt.Transforms(&da)
da.SetColor(bs.Color)
for _, d := range bs.XYZs {
x := trX(d.X)
y := trY(d.Y)
if !da.Contains(plot.Point{x, y}) {
continue
}
rad := bs.radius(d.Z)
// draw a circle centered at x, y
var p vg.Path
p.Move(x+rad, y)
p.Arc(x, y, rad, 0, 2*math.Pi)
p.Close()
da.Fill(p)
}
}示例3: Plot
// Plot draws the Line, implementing the plot.Plotter
// interface.
func (pts *Line) Plot(da plot.DrawArea, plt *plot.Plot) {
trX, trY := plt.Transforms(&da)
ps := make([]plot.Point, len(pts.XYs))
for i, p := range pts.XYs {
ps[i].X = trX(p.X)
ps[i].Y = trY(p.Y)
}
if pts.ShadeColor != nil && len(ps) > 0 {
da.SetColor(*pts.ShadeColor)
minY := trY(plt.Y.Min)
var pa vg.Path
pa.Move(ps[0].X, minY)
for i := range pts.XYs {
pa.Line(ps[i].X, ps[i].Y)
}
