What is a bivariate choropleth map?
Typical choropleth map in Tableau Consultant in Saudi Arabia only give a value for each
polygon. Bivariate Choropleth map rather color encoding for each polygon that
shows two different, but relevant values. It’s very easy for readers and more
easily evaluate how two values change with relationship one another.
Bivariate choropleth maps in Tableau
One of most important step is to start simplifying your
data. Because a bivariate map shows all combinations of two features, it
quickly become visually complex. A map with two binary features has four
specific colors and a map with three categories for each attributes has nine
distinct colors and so on.
Classic suggestion the number of objects we can hold in
working memory, its easier to see why maps with more than nine color
combinations are trickier to interpret, they have too many categories to
remember.
For numeral data BI Consultant in Saudi Arabia, create no more than three data groups. How you
build them will depend on the two features for your map and what makes sense
for comparisons between them. Thumb rule is a good way that if you can make
valid comparisons between the maps when side by side, you can compare them when
they are on a bivariate map.
Once attributes are converted into dimensions with three
groups, creating the bivariate map comes next. For some attributes, it may work
to simply use both attributes on the color shelf (Tableau Consulting Services in Saudi Arabia), but its a very easy
and more flexible to build a new filed with a single, unique entry for each
combination of features. By creating a calculated field, I defined which values
are grouped together and have full control over the colors assigned to each
combination of values.
