   @Ovilia 
   As per dataset documentation I need to convert above data to below format to plot in line chart for different products with time on x axis
   dataset = {
   dimensions: ['date', 'p1Value', 'p2Value', 'p3Value']
   [
   {date: "2019-05-21 00:00:00 UTC", p1Value: 100, p2Value: 50},
   {date: "2019-05-19 00:00:00 UTC", p3Value: 200},
   {date: "2019-05-18 00:00:00 UTC", p1value: 70, p2Value: 125, p3Value: 55}
   ]
   }
   
   But problem is data is dynamic and there might not be value for all products at particular time (19th only p3 has data). So for such nodes tooltip is showing remaining values as empty. Ideally it should not show empty values if there is no point on line chart.
   Ex: If p3Value is turned off from legend and there is no point on remaining lines at 2019-05-19. But by hovering it is showing tooltip at 2019-05-19 with empty values.
