Data (coming from RFXCOM gas/water/power meter)
44509,760
44510,090
44510,480
44511,010
44511,320
44511,840
In a graph this looks like a graph growing and growing. Not very useful.
Better would be if it had the difference between the current data and the last measurement (Delta) like:
0.330 (44510,090 - 44509,760 - etc)
0.390
0.530
0.310
0.520
Q: Is it possible to solve this when WRITING the data to the DB?
Q: Is it possible to solve this when creating Charts?
