Demo analysis of precip-by-state in the amazon
A) View maps
A.1) check ‘Environment>Precipitation’
A.2) check ‘Demography>Brazil population’
Scroll or zoom the map so you can see South America
B) Create analysis groups on the bridge
B.1) drag ‘Environment>Precipitation’ from layers window onto Bridge>Data Layers 'Drop layers here'
B.2) drag ‘Demography>Brazil population’ from layers window onto Bridge>Boundaries 'Drop layers here'
B.3) double click the layers in the drop zones to open attribute tables
B.4) click Bridge>‘Add Group’ twice
B.5) highlight (jan, feb, mar) in 'Attributes(Precipitation)' with click-shift-click & drag to Group A (Drop Attributes Here)
B.6) drag admin_name from 'Attributes(Brazil Population)' to Group B (Drop Attributes Here)
B.7) drag ‘Mean’ from floating stats window (e.g. std dev, count, min -> hiding behind bridge) to Group A
C) Create a graph of mean precip (points) by state (polygon)
C.1) click ‘Graph Types>Bar Graph’
NOTE: if you can't see the graphs click the arrow on 'Layers' to collapse window.
C.2) drag Group A (jan,feb,mar + Mean) to Y-axis (Drop GROUPS here)
C.3) drag Group B (admin_name) to X-axis (Drop GROUPS here)
C.4) click graph (should generate a bar graph in approx 5 secs)
NOTE: hover over bars to see labels and values.
RESULT the graph should show mean precip (jan, feb, mar) for each state. It has interpolated the mean from all of the sampling stations within the polygon. There are tooltips over the graph data points.
Further exploring:
- if you drag different stats (e.g. max or min) or colour patches onto the 'Group A' then click graph, it’ll update
- the cholera/broad street pump example works with the box plot, skip the bridge, and drag the layers onto Y-Cholera deaths & X - Broad St pumps
- the 'Advanced' tab will allow you to add R graphing parameters - this feature is experimental and has bugs
