[QGIS-ZA-user] QGIS Legend Problem

Wed Jul 19 06:57:38 PDT 2017

Hi, I had this problem some time ago and it was raised as a QGIS bug that needed fixing because if you set the style programmatically using the colour codes it just gives a black legend.  Not sure if it has been fixed yet – it appears to be a problem with all GIS and all geological maps.
Here is a style file using the colour codes with no legend

and another that was done manually be editing the style file in notepad++
It uses the typical Gauteng Geology map and its colours and I summarised the geology map to minimise the pain

Maybe if you follow its logic you may be able to do one that suits your purpose

Hi All,

Attached a much smaller ZIP file with Shapefiles :-[. It has only a few polygons.

Regards

Immo

Hi, Immo

Could you send us a copy of the layer you are trying to render with a legend, or a clipped section of the layer? That will help with the testing...

Thanks

Dean

Hi Immo,

Which version of QGIS are you using?

Good Morning Everyone,

I have a geology layer with a few columns, including the chronostratigraphic symbol, the rock type description and, importantly, a colour column (String type). The values stored in the colour column are the HTML hex values for the colour according to the 1 : 1 000 000 simplified geological map of South Africa.

When I open the layer and select the colour column for colouring the lithological units it works beautifully, but I do not get a legend for the composer. But if I set the Properties|Style to Categorized and then again select the colour from the Colour column in the table I also get the same nicely coloured map according to the colour column, an a Legend. But the Legend is wrong...it chooses random colours! What am I doing wrong? Is there a way to get a correct legend, also only showing the units which are actually on the map in the composer. I can set the colours manually to match the value in the colour field but that sort of defeats the purpose.

Thanks for your help so long,

Immo
