We start thinking about the bar chart we made that showed various product categories and a trend line for a chosen category. We send off another e-mail to IT to see whether they can compile the data into a JSON feed. A few minutes later, we get a reply stating that Roshan has asked for the same thing. They are still trying to get everything working, but in the interim, they created a mock JSON feed. They also sent along the URL.
We load the JSON feed in our browser. They moved all the category data into an object called categories
. They also created an object called labels
to hold the ticks for our chart:
