I believe that setting your chart type Strings in a SUBMIT event handler
without persisting them - effectively does nothing for you. They will be
reset to null before the successive page sees them.
Unless you set your chart type in a "PRE" event of the successive page
(onActivate ...) - I believe you'll need to @Persist your chart types ..
Something like:
@Persist
@Property
private String dailyChart, monthlyChart, yearlyChart;
Make sure @Persist and @Property apply to all the relevant Strings.
