Hi Ruby,
Building on the answers of the others:
1) You may not have any geometry in your layers, so there is nothing to
display in the symbology because there is no geometry type. a) For example
if you only have an attribute table, for example the '.dbf' of a shape file, or
a text file like a '.csv' file, or the text file has been imported without
geometry, in which case you need to open it again. b) You may have done the
join in reverse. You may have joined the geometry layer to the attribute/text
layer. That would result in there being no geometry. i) Open the other
properties dialog of the other layer and see if there is something in the
symbology tab. a) If so remove the join from the first layer, and
do the join from the other layer instead. b) adjust the symbology
in whichever order you see fee it will not make a difference. c) if
not you may not have any geometry, so there is no spatial information to
display symbology for.
2) If you look at the top of Properties dialog do you see a drop down menu that
says "No Symbols" and a line of text in the middle of the dialog that says "No
symbols will be rendered for features in this layer." In that case you just
need to switch the dropdown menu to your desired display type that is
appropriate for the data type of the fields (see Richard's answer).
3) Kirk's answer is not applicable :-), since a layer with geometry but no
features should still have adjustable symbology.

Hi, I am trying to create a standard global map on the prevalence of maternal
health issues. I have added my datasets and joined them, however when I go to
the ?Symbology? section to colour code the map, it is blank. Do you know why
this is and how I can change this to be able to create my map.
Thank you
