Origin Ver.: 8.0 SR4
Operating System: Win Vista
Hi all,
is it possible to set the position of a text object that is on a graph page? I mean to put in the coordinates of the object on a page.
Thanks in advance,
Ingo |

Hi Ingo:
If you added those text manually, maybe now the problem is what's the object names? You can use list -o to list all object in the layer. Since there are 5 layers in your graph, you can also use page.active property to active each layer. For example
for( ii = 1; ii <=5; ii++ )
{
page.active = ii;
ty "Objects in layer $(ii) are:";
list -o;
}
Then you can use .x and .y properties to modify the object position.
Thanks

Will the next version add more control for all the objects in the property GUI? I found it tiring to do as you suggested.

Sorry, but both suggestions didn't work for me.
Maybe I need to explain my problem in detail:
I have a graph and it has 5 arranged layers. They are arranged using:
ArrangeLayers 5 1;
Now I want to label each layer using A, B, C, D, and E. So I use the "Text Tool" and add each letter by hand. Now I want to arrange all letters like the layers. But I cannot find how to set the coordinates of the letters which are set as text. Is there a way to do that? |

The GOBJECT datatype was added sometime during Origin 8 development. It's in 8SR6, but I'm not sure which release introduced it.
It isn't really needed here because any graphic object has .x and .y properties and they can be used to position the object relative the XY scale of the containing layer. Note that the coordinates represent the center of the graphic object.
For more precise positioning (and for positioning on the page regardless of the layer - this was the original question) you need to refer to the page.
The Page dimensions are initialized from the current default printer and establish both a resolution (in dots per inch) and a size (in dots). Knowing these two values you can get the width and height of the page in inches:
WidthInInches = PAGE.WIDTH / PAGE.RESX
HeightInInches = PAGE.HEIGHT . PAGE.RESY
Rather than use layer-scale-relative X and Y to position an object, you can use this page frame of reference, but it's up to you to figure out where these dots are and - here's the wrinkle - you position the top-left of the object, not the center. And top, left, height and width are in 'dot' units.
Here is an example that creates a label and positions it on the top edge of the layer and flush right to the layer edge:
layer.unit = 5;
label -a X2 Y2 -n MyLabel Position me at the upper right;
MyLabel.Top = Layer.Top - MyLabel.Height;
MyLabel.Left = Layer.Left + Layer.Width - MyLabel.Width;

Thanks Sam,
I have added a text object and it's name was "Text" like in your example. So I could directly paste your suggested code in the Script Window and it didn't work. Is this variable new and maybe only available in 8.1?
