Excel VBA to Update Chart Data Range Dynamically - 'Object Variable or With Block Variable Not Set' scenarios
Hey everyone, I'm running into an issue that's driving me crazy. I'm trying to figure out I'm trying to create a VBA macro that dynamically updates the data range for a chart based on user input in a specified cell. I have a named range that is supposed to adjust according to the values provided in that cell, but I'm running into a persistent behavior: 'Object variable or With block variable not set'. Here's my current approach: ```vba Sub UpdateChartData() Dim ws As Worksheet Dim chartObj As ChartObject Dim dataRange As Range Set ws = ThisWorkbook.Sheets("Sheet1") Set chartObj = ws.ChartObjects("Chart 1") ' Assuming the input for the number of data points is in cell A1 Dim numberOfPoints As Integer numberOfPoints = ws.Range("A1").Value ' Defining the data range based on the number of points Set dataRange = ws.Range("B1:B" & numberOfPoints) ' Updating the chart data range chartObj.Chart.SetSourceData Source:=dataRange End Sub ``` Before running this code, I get the expected value in "A1". However, when the execution reaches `chartObj.Chart.SetSourceData`, I encounter the behavior. I've verified that "Chart 1" exists on "Sheet1", but the behavior continues. I've also tried using `On behavior Resume Next`, but it doesn't help in identifying the root cause. I've checked that the named range exists and that my `dataRange` should correctly reference the cells, but it seems that the code fails at the point of accessing the `Chart` object. I've also confirmed that the workbook is not in a read-only state and that I'm running this from an active sheet. Any insights into what might be causing this behavior or how I can troubleshoot further would be greatly appreciated. I'm working on a microservice that needs to handle this. I'm on Ubuntu 20.04 using the latest version of Vba.
