误差棒

问题描述

我试图在点上绘制带有误差条的X-Y图（显示该点平均值的标准误差）。有没有办法在MS Chart中执行此操作？

I am trying to plot an X-Y graph with error bars on the points (showing the Satndard error of the mean for that point). Is there a way to do this in MS Chart?

推荐答案

基本上，

	'Create error bar series
	Dim seriesError As New Series("ErrorSeriesName")
	chart.Series.Add(seriesError)

	'Set error bar chart type
	seriesError.ChartType = SeriesChartType.ErrorBar

	'Link error bar series with data series
	seriesError("ErrorBarSeries") = "DataSeriesName"

	'Set error calculation type
	seriesError("ErrorBarType") = "StandardError"

	'Set error bar upper & lower error style
	seriesError("ErrorBarStyle") = "Both"

	'Set error bar center marker style
	seriesError("ErrorBarCenterMarkerStyle") = "Circle"
