    Unable to programmically update points on a Chart in vb 2010

    I am using vb 2010 in VS 2010 Express.

    I have a Chart control which is named Chart1.

    Imports System.Windows.Forms.DataVisualization.Charting

    I tried to change one of the Title lines with the following code:

    Chart1.titles.SpNameTitle.text = "Tom Jones"

    I am getting this error on the Chart1 part of the above code: 'Chart1' is not defined. It may be inaccessable due to it's protection level.

    How can that be? My chart is named Chart1?

    The error doesn't sound right for my recommendation, but a chart uses a Titles collection to hold multiple titles. Try the following...

    Code:
    Chart1.Titles(0).text = "Tom Jones"
    kevin

    ps.. Tom Jones is one cool dude

    RESOLVED: Unable to programmically update points on a Chart in vb 2010

    I solved my own problem.

    As I was stepping out of the shower, it occured to me that the chart control was corrupted. So I deleted the Chart1 control and added it back and everything is fine.

    Sorry about the time waster!
