OriginPro 8.1 SR1
v8.1.13.88 (Academic)
Windows 7

Hi,

How can one plot one dataset (raw data from experiment) above and separated to another plotted dataset on one graph-page to compare both?

I do not know the solution without using Origin C, but would like to do it with written code for easier reuse.

Thanks for help,
Stefan Bollmann

Hi Stefan Bollmann,

Do you mean change the size of the layer? If so, you can activate the graph and then select menu Format: Layer to open the Plot Details dialog. In the dialog, you can select the layer from the left panel, and then change the size in the Size/Speed tab of the right panel. Please refer to this page.

Hi Stefan Bollmann,

In Origin C, the methods OriginObject::GetFormat and OriginObject::ApplyFormat can be used to get and set format for an Origin object. You can refer to the examples about how to access graph format with theme tree. The following code will set all the graph layers to be the same position and with the same size.

void testLayer()
{
	GraphLayer glActive = Project.ActiveLayer();
	if(!glActive)
		return;
	
	GraphPage gp(glActive.GetPage());
	if(!gp)
		return;
	
	foreach(GraphLayer gl in gp.Layers)
	{
		Tree trFormat;
		trFormat = gl.GetFormat(FPB_ALL, FOB_ALL, true, true);  // get theme tree
		trFormat.Root.Dimension.Left.dVal = 15.0; 
		trFormat.Root.Dimension.Top.dVal = 10.0;
		trFormat.Root.Dimension.Width.dVal = 30.0;
		trFormat.Root.Dimension.Height.dVal = 35.0;
		gl.ApplyFormat(trFormat, true, true);  // set the format tree to the graph layer	
	}
	//out_tree(trFormat);  // can print the theme tree to see the format
}

Hey, that was good. Thanks again. Even if I once saw that help page I didn't know what to do with it. Now I know and these hints make me more productive.
