Show busy indicator while updating data

[Benjamin]

Currently my app has 3 switches, when user tap of the switch i will update some chart data in my tab view,

Currently when the switch is tab, the switch will delayed respond, the switch did not change its isOn state visually. only after all charts has being updated, then the state will change.

what i expected is as follows

1. User tap on switch
2. Switch change it's isOn state visually
3. Busy Indicator show isBusy animation
4. code proceed to get the chart data and update the corresponding chart
5. Busy Indicator isBusy false. 
6. Chart shown updated data

my current code

While the data is loading the barBusyIndicator is not showing at all

Inside loadBarChartData(), just before the method end, i have added isVisible and isBusy to false

I will think about how to provide the sample.

In the meantime, as i am using tabview to display the data. would like to check if it is possible to render content for each tabs in parallel.

the contents to be render in various tabs include, doughnut chart. bar chart, line series, dynamically inserted content and sfdatagrid.

upon app loaded up or when filter is being applied, to show the busy indicator.

Hi. I have seen the sample provided.

would like to check if it is possible the following scenario?

User enter page > app load tab view and switches > app display busy indicator while getting data for chart and data grid > app load data and render chart and data grid > busy indicator is hidden

You may assume this request has been fulfilled as I achieved what I wanted following another guide from Xamarin.Forms forums
