代码:

func Chart() {
	values := [][]float64{
		{65706, 66390, 60649, 56504, 53786, 52932, 72626, 57316, 65547, 57382, 56146, 53667, 53097, 57409},
		{45705, 46607, 39843, 33040, 32105, 25387, 51778, 63254, 63402, 50700, 51853, 45923, 46298, 54673},
		{25213, 23734, 23470, 24244, 11602, 10932, 18507, 11343, 10174, 14269, 14511, 5166, 3672, 6517},
		{5756, 8977, 7739, 5177, 4363, 3223, 9964, 6189, 8359, 5743, 5572, 4029, 4365, 8164},
		{2991, 3230, 3120, 2837, 2285, 2271, 3168, 3202, 3167, 3296, 3030, 2439, 2446, 3158},
	}
	xAxis := []string{"20231212", "20231213", "20231214", "20231215", "20231216", "20231217", "20231218", "20231219", "20231220", "20231221", "20231222", "20231223", "20231224", "20231225"}
	legends := []string{"x1", "x2", "x3", "x4", "x5"}
	painter, e1 := charts.LineRender(
		values,
		charts.TitleOptionFunc(charts.TitleOption{Text: "Trend", Left: charts.PositionCenter, FontSize: 20}),
		charts.XAxisOptionFunc(charts.XAxisOption{Data: xAxis}),
		charts.LegendOptionFunc(charts.LegendOption{Data: legends, Left: charts.PositionRight}),
		charts.WidthOptionFunc(1600),
		charts.HeightOptionFunc(800),
	)
	if e1 != nil {
		fmt.Println(e1.Error())
		return
	}
	data, e2 := painter.Bytes()
	if e2 != nil {
		fmt.Println(e2.Error())
		return
	}
	file, e3 := os.Create("chart.png")
	if e3 != nil {
		fmt.Println(e3.Error())
		return
	}
	if _, e3 = file.Write(data); e3 != nil {
		fmt.Println(e3.Error())
	}
}


效果:

之前版本的计算问题,可能需要确认一下如何调整更方便。如果不是必须要使用golang的,那么可以尝试使用: https://charts.npmtrend.com/ ,提供了json形式配置生成图表,更简单方便,可直接使用docker部署。
