QGIS 2 Lesson 17 - Advanced Labeling Using Expression Dialog in QGIS

Data available at www.dmad.org.tr/qgis-2-lesson-17
Hi and welcome to the Lesson 17 in DMAD - Marine Mammals Research Association's second free QGIS course. This course if for beginners to intermediates. In this lesson we will look at how we can unicode the expression dialog to make our labels virtually infinitely customisable. It looks a bit tricky because we use unicode but we've broken it down into simple sections for you.

Excelent explanation

Thanks a lot.

Thanks for these videos! I don’t know why but when I go to add the Area column in the attribute table for the Potential areas layer I don’t get the same values you do... I can do the ID column 1-103 no problem but my Area column values are different and my highest is 10.34 not 9.88 (with decimal number real and precision 2 selected)

Hi Hanna, this is probably just down to decimal rounding errors during other lessons, either on my side or yours. I wouldn't worry too much, just when you do this for real make sure you stick with the same format throughout.

hi. how put in differents color each name? pls
like using color_rgb()

[@Marisacostawr]

In my field calculator , I cannot change the precision or field lenght. Any ideas?

[@DanielAlvaradoOspino]

I have the same problem

[@dmadmarinemammalsresearcha3966]

Hi, if you're having this error than you can try to force QGIS to round your decimal using the expression - round($area,3) - where 3 is your precision and can be adjusted to whatever suits you.

@@dmadmarinemammalsresearcha3966 I thought that could be a way to do it, thanks!
