Our census application from previous chapters could use some visual appeal when it comes to presenting data. We'll make our first attempt at adding charts and graphs using the dojox/charting
library. We'll apply the graphs to the map popup whenever the user clicks on a census block group, county, or state. The census blocks don't have enough information for us to graph.
Since our graphs are currently limited to our census application, we need to update the modules in our custom y2k/Census
module definition:
We'll start by adding
dojo/on
to handle the map popup events.We'll add the default chart object along with a pie chart and a bar chart module.
We'll add the
PrimaryColors
theme andSimpleTheme
to create our own custom color template.Finally, we'll add a highlight and a tooltip action to let the user read the results when they hover over parts of the graphs.
It should look a bit like the following:
define([… "dojo/on", "dojox/charting...
