How to copy a graph from one Form to another

[rv]

Hi,

I need to copy a graph from one Form to another (all the series, presentation, data....).

I've try with a MemoryStream but it crash at the load....

what's wrong ?

To simplify, I've try with 2 graph on the same form iwth the following code :

System.IO.MemoryStream stream = new System.IO.MemoryStream();
try
{

tChart1.Export.Template.Save(stream);
// 2) Load the template into other Chart...
stream.Position = 0;
tChart2.Import.Template.Load(stream);
// restore the chart alignment (in this example)
this.tChart2.Dock = DockStyle.Fill;
// repaint the Chart
this.tChart2.Refresh();
}
finally
{
// remove the stream, it's no longer necessary...
stream.Close();
}


This code crash at the Template.Load.

What's wrong ? I've try with the new TeeChart version with no success...

Thansk for your help.

Hi ..

Using version 1.1.1644.16795, the latest public version, the following code works as expected here:

Code: Select all

private Steema.TeeChart.Styles.Bar bar1;

private void Form1_Load(object sender, System.EventArgs e) {
	bar1 = new Steema.TeeChart.Styles.Bar(tChart1.Chart);
	Random rnd = new Random();
	tChart1.Aspect.View3D = false;
	for(double i=1;i<=48;++i) {
		bar1.Add(i,rnd.Next(100),Color.Red);
	}
}


private void button1_Click(object sender, System.EventArgs e) {
	System.IO.MemoryStream stream = new System.IO.MemoryStream(); 
	try { 

		tChart1.Export.Template.Save(stream); 
		// 2) Load the template into other Chart... 
		stream.Position = 0; 
		tChart2.Import.Template.Load(stream); 
		// restore the chart alignment (in this example) 
		this.tChart2.Dock = DockStyle.Fill; 
		// repaint the Chart 
		this.tChart2.Refresh(); 
	} 
	finally { 
		// remove the stream, it's no longer necessary... 
		stream.Close(); 
	} 

}

Hi Herve,

I've posted one example (which works fine here) in the steema.public.attachments newsgroup. Could you please test it ?

Hi.

I've tried the following code and it worked just fine:

Code: Select all

      System.IO.MemoryStream stream = new System.IO.MemoryStream();
      try
      {
        tChart1.Export.Template.Save(stream);
        stream.Position = 0;
        Form2 f = new Form2(); // target chart on different form
        f.tChart1.Import.Template.Load(stream);
        f.tChart1.Dock = DockStyle.Fill;
        f.tChart1.Refresh();
        f.Show();
      }
      finally
      {
        stream.Close();
      }   

I've also posted complete VS2003 project demonstrating this at steema.public.attachments newsgroup.

Hi,

I may have a problem with my .NEt config because it still doesn't work.

I've try with your code, and I get the following :
