A Fast Way to Color Polygon With 200 Row With Six Selected Color in QGIS 3.4.2












5














I have a layer of the world that contains 200 rows.



I am required to color the map with six selected colors, the rainbow colors.



enter image description here



I figure that I can save selected countries and save them separately.



enter image description here



Once they saved I can upload them and make the color ramp I needed.



enter image description here



However, I was wondered is there a faster way to do this without making six layers and without choosing each country manually in the Layer Styling bar panel.

          Following further clarification by Nitzan Matan, this is another map representation.



          enter image description here



          This categorization was made by round((y(centroid($geometry))+80)/30) .



          To divide latitude range (-90 ~ +80) in this sample data from Natural Earth into 6 zones (bands), I first added 80 and divided by 30. You will need to modify these numbers according to your dataset.



          enter image description here



          Now change the color to fit with your rainbow palette.



          NB One caveat - you will notice Alaska is green. If you want it to be like Russia and Canada, consider breaking US into parts.

            @NitzanMatan Yes, more specifically the latitude ranges (-90.00000 ~ 83.64513) and found as part of Extent in the Layer Properties | Information. But I need to know only the y-coord of centroid so it does not have to be such precise.

          As you are using QGIS 3.4.2, you can use Topological coloring Tool, which is in the Processing Toolbox | Cartography.



          Start this tool and give 6 (any number of colors you want to have) in the Minimum number of colors and hit Run. It will return a new layer Colored with an additional integer field color_id.



          So the last step is to open the Layer Property of this layer and set Categorized color scheme on the color_id column (field). You then change each of these 6 random colors to your rainbow palette.

          • Sure, in your answer you made 6 colored id, They are scattered randomly. In group 1 there are row both in Africa and the U.S. I need that Russia and Canada will be one color, U.S and Europe and so on. Thanks!
