VBA Code scenarios to Update Chart Data Source Dynamically - 'Method 'Chart' of Object '_Worksheet' scenarios'
I've tried everything I can think of but I've hit a wall trying to I tried several approaches but none seem to work... I'm trying to update the data source of a chart dynamically using VBA in Excel 2016, but I keep running into the behavior 'Method 'Chart' of Object '_Worksheet' Failed'. The chart is on a separate worksheet, and I'm attempting to set its data range based on user input from a form. Here's the relevant portion of my code: ```vba Sub UpdateChartDataSource() Dim ws As Worksheet Dim cht As ChartObject Dim newRange As Range Set ws = ThisWorkbook.Worksheets("ChartData") Set newRange = ws.Range("A1:C10") ' Assuming data to chart is in this range Set cht = ThisWorkbook.Worksheets("ChartSheet").ChartObjects(1) ' Getting first chart object cht.Chart.SetSourceData Source:=newRange End Sub ``` I've confirmed that the names for both worksheets are correct and that the chart exists on the specified sheet. When debugging, it seems that `cht.Chart` is returning `Nothing`, which is unexpected since I verified that the chart object is indeed present. I've also tried explicitly referencing the chart with `Set cht = ws.ChartObjects("Chart 1")`, but that leads to the same behavior. I need to make sure the chart updates automatically whenever the user modifies the input data. Are there any best practices for handling chart updates in VBA or tips on resolving this behavior? Additionally, could user permissions or workbook protection settings interfere with modifying chart data sources? Any ideas what could be causing this? Thanks for any help you can provide! Has anyone else encountered this?
