I have a dashboard created with a PIE chart. I want to add on the dashboard start and end time for which this pie chart is created. Let us say this chart is created for doing a 24 hrs data analysis and creating the PIE chart.
Start time : now-24h End Time: Now displayed above the Pie chart.
if that is not possible at least I need that start and end time printed on somewhere in the chart when I send it as email PDF to clients. so they know this report is for the data period starting and ending used
You can use | addinfo to create info_min_time and info_max_time fields and create tokens and then use these in the title of the dashboard panel with My panel name from $info_min_time$ to $info_max_time$.
