Represents the error bars for a series. Error bars indicate the degree of uncertainty for chart data. Only series in Radar, Polar, Area, Bar, Column, Line, and XY (Scatter) charts can have error bars. Only series in scatter charts can have x and y error bars. The ChErrorBars object is not a collection. There is no object that represents a single error bar; you either have x error bars or y error bars turned on for all points in a series or you have them turned off.
Using the ChErrorBars object
The following methods return a ChErrorBars object. For more information, see the Help topics for these methods:
The following example adds error bars to the first series in the first chart in ChartSpace1, and then sets the properties for the error bars.
Sub AddErrorBars() Dim chConstants Dim ebCollection Dim ebSeries1 Set chConstants = ChartSpace1.Constants ' Set a variable to the collection of error bars for ' the first series in the first chart of Chartspace1. Set ebCollection = ChartSpace1.Charts(0).SeriesCollection(0).ErrorBarsCollection ' Add error bars to the chart. ebCollection.Add ' Set a variable to the error bars for the data series. Set ebSeries1 = ebCollection.Item(0) ' Set the error bars so that they represent a certain ' percentage of the value of a data point. ebSeries1.Type = chConstants.chErrorBarTypePercent ' The error bars represent 5% of a data point. ebSeries1.Amount = 0.05 End Sub
