VBA: How to Properly Handle Dynamic Range Selection for Chart Data without Errors?
I've been working on this all day and I'm trying to create a dynamic chart in Excel VBA that updates automatically based on the range of data I have. The goal is to select the last filled row in a specific column and use it to define the range for my chart data. However, I'm working with an scenario where the chart doesn't update correctly, and sometimes it throws a "Run-time behavior '1004': Unable to set the SeriesCollection property of the Chart class". Here’s the code snippet I've been using: ```vba Sub UpdateChartData() Dim ws As Worksheet Dim chartObj As ChartObject Dim lastRow As Long Dim chartRange As Range Set ws = ThisWorkbook.Sheets("Data") lastRow = ws.Cells(ws.Rows.Count, 1).End(xlUp).Row ' Assuming data is in column A Set chartRange = ws.Range("A1:B" & lastRow) ' Dynamic range based on last row Set chartObj = ws.ChartObjects("Chart 1") With chartObj.Chart .SetSourceData Source:=chartRange End With End Sub ``` I've verified that the chart object name is correct and the data in column A is not empty. However, when I run this code, it sometimes fails with the mentioned behavior, especially if I have a large dataset. Is there a more reliable way to create this dynamic range or to set the source data for the chart? Any tips on best practices for handling dynamic ranges would also be appreciated. Thank you! Has anyone dealt with something similar?
