I�d like to have the filename and
graph name in every Origin plot of
my project. To achieve this I use
the system variables %G and %H in
a text item.

To duplicate text on all graph windows
in one project one uses the "master page".

Thus I added a text field containing:

filename: %G (%H)

to the master page.

In Origin 5.0 w/o patches the text appears fine on all graph windows showing the file- and window-name.
Caused by a BUG in this version one cannot
print master items. The remedy is to patch ORIGIN to service release 2.

Doing so, I can now print master items
BUT the %H variable is now shown as "MASTER" on all pages instead being the window name of each individual graph plot.

Please help, what can I do to get the correct window name back?

If you are using graph templates you can add a script to each template which will add the information automatically. Here's what I do in Origin 6.0.

A) Create a text label somewhere on the graph with the word "temp".
This text will be replaced by the path info later so it's not
important.
B) Right click on the text and select LABEL CONTROL. A dialog box
should appear.
C) Add the following code.

%P="\v(%H from %X%G.OPJ)";
label -s -sa -d (.20*page.width) (.84*page.height) -n Path %P;

This code puts the current window name %H as well as the path %X and
project name %G into the the string %P then uses the label command
to display it at the desired co-ordinates.

D) Change the OBJECT NAME to "Path".
E) Finally you can select when you want this to happen from the
SCRIPT, RUN AFTER drop down listbox. I usually use 'After save'
because the path info and project name are correct that way. Then
when you print the graph you have a record of where everything is.

F) Save the template with the new text label.

I hope this helps. If you have any questions you can email me @ cstorey@canada.com.

The -s and -sa options included in the label command statement are designed to create a label which interprets and expresses any string variable prior to actually creating the label. That way the text that gets entered into the label reflects what is actually stored in your string variables, rather than displaying the string variable itself. In handling it this way, it becomes unnecessary to enable the "Link to Variables" check box.

That being said, you may still be wondering why your label does not get created correctly, hah? Well, I think that the label command line just needs to be tweaked a bit. Specifically:

1. The string variables which contain the window title, path, and filename (%H, %X, and %G) do not require the extra % symbols since the first % symbol should get interpreted by the -s option before the text ever gets entered into the text label.
2. The y component of the -d option is not completely enclosed in parentheses. It needs to have an opening one. I suspect this may have been a typo on your part.

What you end up with is the following:

%P="\v(%H from %X%G.OPJ)";
label -s -sa -d (.05*page.width) (0.98*page.height) -n myPath %P; 
myPath.fsize=10;

Try it out and see if it works for you. Again, the correct label should show up without the need to check the "Link to Variables" check box. It should also not require a refresh.

the answer to the missing "\" is the use of
the \v( ) notation (also mentioned in the LabTalk helpfile, section "string system variables"). This will retain the backslash.

Now I changed the script to:
%P="\v(%%H from %%X%%G.OPJ)";
label -s -sa -d (.05*page.width) 0.98*page.height) -n myPath %P;
myPath.fsize=10;

This way the label contains VARIABLES and not the content of the variables. Thus the label will reflect changes in the file- and windownames. Theres one drawback. One has to
enable "link to variables" in the label control box by hand and then refresh the display. Does anybody know how to do this with scripting?

thanks for your help. As I�m not using graph templates I�ll use your script code in the ScriptWindow to add a label to a graph window.

This works fine and also leaves the "\" in the path variable (%X). Strange, but the backslash is removed if I create this text label by hand.

Thanks for trying to help out.
I�d like to comment on your statements as
I think I didn�t make my point clear.

1.
The %P="\v(%H from %X%G.OPJ)"; is the same command which CStorey (see above) used. And
that didn't work as the variables get interpreted. Having said that, it does of course work but not the way we want it to work:
Try
type %P;
Thats what you get in the label: the content of the variables. That�s not what we want! We want the variables themselves in the label. Therefore I used the second % to prevent the label command from resolving the variables.

Try my solution please. It does work. The only thing that�s left is to activate the "Link to variables" thingie. I don�t know how to do that in LabTalk. Maybe you know ?

2.
You are right. The missing bracket is a typo :-)

It is not currently possible to enable the Link to variables check box. I have added a suggestion to our database requesting this feature and have included your information in the suggestion in an effort to increase its priority.

In the meantime, since your methods rely on this setting, you would be better off utilizing graph templates (as was suggested earlier).

For instance, suppose you most often choose to plot line graphs. Line graphs are created by a graph template called Line.OTP. To add the label to Line.OTP, do the following:

1. Open Line.OTP. To do so, click on the Open Template button on the Standard toolbar, navigate to the Origin installation folder, and double-click on the file called Line.OTP. If you aren't sure what the Open Template button looks like, here is is:

   

2. Create a text label in the exact location you would like to see it appear (at all times) and enter \v(%H from %X%G.OPJ) in Text Control. Click OK.
3. Alt + double-click on the text label to access Label Control.
4. Select Window Activate from the 'Script, Run After' drop-down list and enable the 'Link to Variables' check box. Click OK.
5. Choose File:Save Template As and overwrite the existing Line.OTP.

Once you have done this you can create line plots with your new label by selecting Plot:Line or by clicking on the Line Graph button on the 2D Graphs toolbar. Furthermore, every time you activate the graph, the label will update (if the graph, path, or filename has changed).

I apologize for any inconvenience this has caused you and hope that my suggestions prove helpful.

Sincerely,
Ryan Toomey
