Unable to set the xvalues (or values) property of the series class
I'm trying to code a dynamic chart series (two series), with
one common x-axis. The length of the series, and the location of the columns holding the series can both change. I have used the cells method of the range object to do this. It works sometimes, and other times I get the error shown in the subject of this email. This is the code: Dim nrows As Integer, ncolumns As Integer 'sheet containing the data series and xvalues Sheets("Intermediate Output").Select 'determine number of rows to plot Range("a1").Select Selection.End(xlDown).Select nrows = ActiveCell.Row 'determine number of columns having data Range("a1").Select Selection.End(xlToRight).Select ncolumns = ActiveCell.Column Charts("BOD Plot").Activate With Worksheets("intermediate output") 'define ranges for series ActiveChart.SeriesCollection(1).XValues = _ .Range(.Cells(2, 1), .Cells(nrows, 1)) ActiveChart.SeriesCollection(1).Values = _ .Range(.Cells(2, (ncolumns - 1)), _ .Cells(nrows, (ncolumns - 1))) ActiveChart.SeriesCollection(2).XValues = _ .Range(.Cells(2, 1), .Cells(nrows, 1)) ActiveChart.SeriesCollection(2).Values = _ .Range(.Cells(2, (ncolumns - 2)), _ .Cells(nrows, (ncolumns - 2))) End With When it DOESN'T work, if I step through the code and insert the cursor at various places to attempt to ascertain what actual values the program is getting for the cells, I may find something like "(ncolumns-2)=331"! Which doesn't make any sense to me, as ncolumns itself may only equal 36!! Does anyone have any ideas for how to fix this, or why it doesn't work??? Thank you all, Kate |

Unable to set the xvalues (or values) property of the seriesclass
I'm answering myself, since no one else did. What I discovered is
that, when a chart series' values become based upon cells that are empty, new values cannot be reassigned programatically! Why? Go figure, musta seemed like a good idea at the time. In my particular workbook problem, I have a persistent chart the values for which are repeatedly erased and replaced as the model is run. I had to create a hidden sheet with dummy values that I switched the series to, before the data sheet was erased, and then switched back to the new data, in order for the series to be updateable. Now isn't that ridiculous! -Kate Kate wrote: I'm trying to code a dynamic chart series (two series), with one common x-axis.
