Be able to Visualise Long time (e.g.>=25 Hour) Tiles without having to leave dashboard open

[elongo]

If I have a tile (Line chart) set to display 25 hours data, I have to leave the dashboard opened so it plots the data.Would be helpful if one can simple close dashboard and browser and when coming back see the tile with its >= 25 hours data. Now if I come back, the tile is empty and need to wait hours to start seeing a chart.
