Does anyone have experience with the "multiple attributes" then
"quantity by category", then "field" and "normalization" capability in
"Symbology"? I'm trying to graphically represent temperature change in
a whole river network during the year by months. For each individual
month, I've successfully got a pretty good representation of the 500+
temperature prediction locations in the river network, by both color
change and symbol size (gradually bigger symbol and toward one end of
the color ramp, the higher the temp). Unfortunately, the map for
September (where the temps range from 10C to 16C) and the map for
January (where the temps range from 2C to 5C) look very, very similar,
as ArcGIS creates the range of color and size based on the discrete
month's range.
My goal is to have the maps graphically different enough that if you
view them together, or sequentially as an "animation" of the year, that
the changes from cold in winter to warmer in late summer would be
clear. And ideally clear enough to perceive that certain places (the
main stem or the headwater reaches?) change less or more than others
throughout the year.
Any ideas? Could it be a easy as "normalizing" by putting the warmest
month in the "normalization" field and the month of interest in the
"value" field?
Thanks,
Chris
