I'm getting an error when trying to set the chart range of a chart.
I've narrowed the problem down and figured out that it occurs when
there is no data in the data range i'm trying to set the chart to.
Any workaround for this?

This is the code i'm using. Chart is activated in a previous set of
code. Columns 1 and 2 (ie x value and series 1 values) always have
data in them. The series 2 column may or may not have data in it, and
may or may not have data in every cell of the range, but I need to set
it anyway. Any ideas on how to fix this problem?

Sub Update_Chart_Ranges(ChartDataRange)
Dim LastRow As Integer
Dim myColumn As Integer, myRow As Integer

LastRow = ChartDataRange.End(xlDown).Row
myColumn = ChartDataRange.Column
myRow = ChartDataRange.Row + 1

ActiveChart.SeriesCollection(1).XValues = "='Actual Chart Data'!R"
& myRow & "C" & myColumn & ":R" & LastRow & "C" & myColumn
ActiveChart.SeriesCollection(1).Values = "='Actual Chart Data'!R"
& myRow & "C" & myColumn + 1 & ":R" & LastRow & "C" & myColumn + 1
ActiveChart.SeriesCollection(2).Values = "='Actual Chart Data'!R"
& myRow & "C" & myColumn + 2 & ":R" & LastRow & "C" & myColumn + 2
End Sub
