problem with Geoplot reading table from NUTS shp file

Hi,
It should display different colors in each region proportional to climatic data (stored in HDD_geoT.HDD )
Problem seems when geoplot is reading the shapes from HDD_geoT.Shape
my code:
EU_geoT = readgeotable('NUTS_RG_03M_2021_3035.shp');
% building HDD map on EU_geoT from common fields NUTS_ID and Region
HDD_geoT = outerjoin(EU_geoT, HDD_1721,"LeftKey","NUTS_ID","RightKey","Region");
HDD_geoT = rmmissing(HDD_geoT);
figure
%geoplot (with error!!)
geoplot(HDD_geoT, ColorVariable="HDD");
getting error (same on R2022b online):
geoplot(HDD_geoT, ColorVariable="HDD");
Error using map.graphics.chart.primitive.Polygon
Value must be numeric.
Error in map.graphics.internal.geotableplot (line 49)
h = objectConstructor('Parent', parent, 'SourceTable', tbl, 'ShapeVariable', 'Shape', pvpairs{:});
Error in geoplot (line 68)
obj = map.graphics.internal.geotableplot(gx, args);
Please help!
Alex

Hi Alex,
I understand you are trying to use “ColorVariable” in “geoplot” to display different colours in each region proportional to climatic data but encounter an error.
“ColorVariable” expects its input to be a numeric type. But I notice that the data Type of column “HDD” is 1x1 cell double, it is not numeric.
I hope this helps you.
