| Quick Guides - Scatterplots | |
Scatterplots are a powerful visualization tool that let you compare many locations and data
at the same time, on 2 dimensions.
On DataPlace Scatterplots, each dot represents a place (a State, County, Zip Code, etc.). Each
axis of the scatterplot represents a different indicator.
|
You control the scatterplot using the blue panel on the right side. Here you'll find options to
change each of these things:
-
What type of places are being compared? This changes what the dots represent. You can select
States, Counties, Metropolitan Areas, Zip Codes, Cities and Tracts.
- To what boundary do you want to limit the collection of places? This would for example let
you compare just counties in Texas, or Census Tracts within Washington D.C.
- What indicator do you want to show on each axis? Clicking "Replace Indicator" will let you
choose a different indicator to show. By default, the search will show some indicators that are
similar to the one you are replacing. You can click an 'X' to remove constraints on your search,
thereby generalizing your results to include more indicators. Or you can just click "Start Over"
to choose a completely different indicator.
- Display Options lets you clone your current scatterplot so you can make up to 4 independently
controllable scatterplots. Once you do this, click on the plot you want to control, then use the
blue box to make changes to that plot.
- "Show correlation line" -- check this box to add a blue "best-fit line" to the scatterplot,
as well as computing the statistical "r" factor that measures the amount of correlation between
the two indicators you've selected. For example, Poverty Rate is negatively correlated with % of
high income individuals.
