Errors: error C2059: syntax error : 'this'
error C2039: 'checkBox1' : is not a member of 'System::Windows::Forms::DataVisualization::Charting::ChartArea'
error C2039: 'CheckState' : is not a member of 'System::Windows::Forms::DataVisualization::Charting::ChartArea'

I found out through visual studio chart control.net that the graphs autosize by itself. I want to turn it on by clicking a check box, so I wrote this but I am getting errors. Can anyone help?

I'd say that you placed that function in the wrong class.
What's the name of the class that contains checkBox1?

[epd5030]

I believe the class name is checkBox1_CheckedChanged

[coder777]

I believe the class name is checkBox1_CheckedChanged

No that's the function name.

Look at the error message:

System::Windows::Forms::DataVisualization::Charting::ChartArea

checkBox1 is obviously not in ChartArea.
Just search for the checkBox1 member variable.

Isn't the function automatically generated? How could it be in the wrong class?

I think that my problem might be that auto is not right for autoscaling. I found out that it autoscales by itself and I'm going to write a function that will set the boundaries to the maximum and minimum value when the box is checked.
