requesting historical data to dashboard Hi,i didn't work a lot on mashups but i was thinking of something, lets say i have energy meter that sends me readings that i use to calculate the hourly consumption and then i log it, then i put it in an infotable that has 24 rows representing the past 24 hours, and when i add new reading i delete the oldest one in the infotable so that the table will always be 24 row, then this infotable should be connected to some line chart or bar chart in a mashup to show the 24 values, all of this is fine, if i created a previous and next buttons on the chart so that the user can see the 24 values before the current 24 values, i was thinking maybe create another infotable when the user click the previous data button a query to be run to get the data from the database and put it in this new infotable and then the chart will switch to read from this new infotable, the reason for another infotable is that if i used the same infotable and the user requested the previous data while there is a new read
