My application work in this ways. I got a database collect data from 20 sensors. Database holds Temperature and DateTime data/Records from sensors. So i would like to make it whenever i view the chart, it will plot a line chart one by one according to the temperature and timestamp(DateTime). Which mean my X axis is a colleborate time on that particular date. Anyone did this before or advice ? Thanks.
I already design a in the way that the line chart will plot base on both dropdownlist, Sensor ID and Date. So it will work like whenever i select a Date or ID it will read the records from database table temperature.
