Re: [Qgis-user] custom string formatting for grid coordinate labels

[Neumann, Andreas]

Hi Andrew, 

Thank you for these useful custom expression functions.   

It would be quite useful to have the Python unichr() function available
in QGIS as an expression function under the "String" functions group. 

Thanks and greetings, 

Andreas

I have just posted a couple of unicode superscript and subscript 
functions to GIS Stackexchange:

I have searched for the mark on LibreOffice (insert special

With this expression:

Case
when @grid_axis = 'x' then (substr(@grid_number ,1,5) || '⁰⁰⁰ ᴱ')
when @grid_axis = 'y' then (substr(@grid_number ,1,5) || '⁰⁰⁰ ᴺ')
end

Do I get the coordinates marking shown in the attached image.

Hi,

With Unicode Characters is a good idea. As the code is implemented 
directly in a QGIS-Expression me remains a mystery.
I have searched for the mark on LibreOffice (insert special characters) 
and then copied using CTRL-C / CTRL-V in the expression.


With this expression:

Case
when @grid_axis = 'x' then (substr(@grid_number ,1,5) || '⁰⁰⁰ ᴱ')
when @grid_axis = 'y' then (substr(@grid_number ,1,5) || '⁰⁰⁰ ᴺ')
end

Do I get the coordinates marking shown in the attached image.

That's an excellent idea - thanks for sharing!

Re: [Qgis-user] custom string formatting for grid coordinate labels

[Andrew Harfoot]

Hi Uwe,

If you can't use formatting tags, then possibly Unicode is your friend 
here - have a look at characters U1D31 and U1D3A - superscript E and N 
respectively. Using these should allow you to generate labels like this: 
0234ᴱ  or 345389ᴺ


Cheers,

Andy

Not currently - there's no support for formatting in the coordinate text.

Not currently - there's no support for formatting in the coordinate text.

[Qgis-user] custom string formatting for grid coordinate labels

[Uwe Fischer]

Hello List, hello Nyall,

 

I have a question concerning the grid coordinate labels for map frames in
print composer. If you set the label format to "custom", you get to
"Expression based annotation" box where you can build expressions for
formatting, e.g. concat(left(@grid_number,3) ,  'E'). That works fine
in the editor and the footnote preview shows exactly the desired result (E
as an above positioned little index). But, in the map composer canvas, the
format string is rendered as text, that means E shows up as a text
string there.

 

Is there a way to apply the format rule (which seems to work) correctly to
the map composer?

 

Regards and thanks a lot,

 

Uwe
