Dynamically updating chart data
The report page that we have currently developed shows the data of one single department of Harry's SuperMart. However, as per plan, Harry would review the daily sales of not one, but three of his departments at the end of every week. That means three different charts!
Putting up three different charts on a single page would defeat the whole purpose of showing charts for the report. A quick tip from Harry solved our problem. Harry informed us that he was not interested in comparing the performance between departments. Instead, he was more interested in tracking how each department individually performed on each day of the week. This implied that we could show the three charts on three different pages, one at a time.
Knowing that having a page for each department is slow to browse and also takes more time to develop, we would develop the audit page with a single chart and dynamically update its data.
