How to use custom ucl,lcl and mean and to hide lines and labels generated by control?

[User (Legacy)]

Hi~~

Forgive my rusty english.

I'm wondering the above subject now....

I added custom UCL and LCL contant lines to my X Chart and R chart.

Yes, It works good... but I can't hide the lines and labels generated by 

contol.

I've changed the collection of studies , but in runtime the change doesn't 

work.

Also I think LCL values under 0 in R chart has no meanings....so I want it 

to be hidden.

So I have added code as follows.

   StudyConstant  stdc = ( StudyConstant )this.stsRChart.Studies[2];  // 

hide lcl( '2' is the LCL's index number of studies )

   object[] _icol = ((object[])(stdc.ConstantLines)) ;

   ConstantLine cstl = ( ConstantLine )(_icol[0]);

   cstl.ShowLine = false;

   cstl.ShowText = false;

   stdc.Interactive = false;

   stdc.ShowLabel = false;

   stdc.Visible = false;

   stdc.Value = double.NaN;

   stdc.Text = "";

   stdc = (StudyConstant)this.stsRChart.Studies[0];  // hide ucl( '0' is the 

UCL's index number of studies )

   _icol = ((object[])(stdc.ConstantLines)) ;

   cstl = ( ConstantLine )(_icol[0]);

   cstl.ShowLine = false;

   cstl.ShowText = false;

   stdc.Interactive = false;

   stdc.ShowLabel = false;

   stdc.Visible = false;

   stdc.Value = double.NaN;

   stdc.Text = "";

But it also doesn't work...

How can I use custom UCL/LCL lines and labels?

How can I hide generated UCL/LCL lines and labels?

Because the fractional vlaues of the generated are slightly different from 

my custom values,

I need to do that...

Thanks

Jay.

Control charts always have limits, that's what defines them.

You can change the way limits are calculated by assigning Sigma to the 

Control Chart gallery.

For example:

statistics1.Gallery.XChart.Sigma = 10;
