I created a Design Studio dashboard with 3 data sources (3 BEX Queries) and 3 components namely One Chart and two crosstab components.
To improve performance, I am loading DS_2 and DS_3 with script on doBackgroundProcessing() and calling this method On Startup of application.
I followed below scn link
Performance is improved little bit. When I run the dashboard, Chart will be displayed first, again after 4 secs the same chart gets refreshed automatically. The reason is by that time, DS_2 and DS_3 are loaded through doBackgroundProcessing().
Is there any way to avoid refreshing the first screen again(Chart component) once DS_2 and DS_3 are loaded? Chart component uses only DS_1.
I have searched for this information in SCN but I did not get any information on it.
