Coloring a map

[clarachac]

Hello,

I have a map of Europe with the percentage of pollution in each country.
I would like to color the map going from light yellow for the country with the least pollution, and a 'dark' yellow for  the country with the most pollution.
I have tried this but it doesn't work : 

colormix1(RANK(Num(Sum({<Continent={'Europe'}>}[nbre_usines])/
sum(aggr({<Continent={'Europe'}>}[xxx]),country)
, '##,##%'),0)

,white(),RGB(255,205,0))

If you have the countries on the map as an Area layer, coloring from light to dark is a basic functionality of the map object:

For the measure, select the one giving the pollution values, then choose the desired color scheme.

Yes but I can't choose the color I want, I'm stuck with the color scheme given by QlikSense.
Is there an option to choose the color I want?

Unfortunately, I do not believe this to be possible out of the box with the Qlik Sense map object. These workarounds might however work for you:

• Color by Expression on Map Object

• How to change the color in Data Points On Layered Map in Qlik Sense Geo Analytics

Hi @clarachac ,

The issue with Colormix1 function is that the expression used for the colour grading should lie between 0-1, It seems you have used rank() as your colouring expresession. Try to remove rank & then use the expression, it seems your formula will evaluate into '#0%' values laying between 0-1. Let me know if it worked.

Hi,

You can always create your own theme with the required colour palletes & use that theme in your dashboard.

Thank you all for your answers.

I followed @steeefan's answer, and I used the colors by measure.
I created a Master Item Measure where I chose the colors that I want (cf. image)
