Displaying Max value of every 8 hours
I'm using custom Streaming Data. I use an ESP32 to push the real-time weight value of a sensor to Power BI API. However, I need a table displaying the weight max value of every 8 hours. My date column has date and time combined.
Thanks in advance!
I managed to do all of it. for the Peak, I used this Measure
ShiftPeak = CALCULATE(MAX(RealTimeData[Weight]), TOPN(1, RealTimeData, RealTimeData[DateShift], ASC, RealTimeData[Shift], ASC)) . However, I did a bit of manipulation from the ESP, so I push a DateShift (which is basically just a number value) and three shifts that already got determined by the ESP. Everything will be displayed fine as long as you don't choose Date (The Value that has DateTime. Note this is for API streaming dataset). The other problem that I was struggling with is to calculate the sum of the shift peaks, which miraculously worked with this measureShiftsum = SUMX(SUMMARIZE(RealTimeData, RealTimeData[DateShift], RealTimeData[Shift], "Peaks", MAX(RealTimeData[Weight])),[ShiftPeak]) .If you want to associate every ShiftPeak to which time it's occurred, I used another measure which isPeakDate = CALCULATE(MAX(RealTimeData[Date]), TOPN(1, RealTimeData, RealTimeData[DateShift], ASC, RealTimeData[Shift], ASC, RealTimeData[Weight])) & " " . (if you remove " ") the time won't be displayed for some reason, but the date will.
I'm sorry for the late reply cause I managed to do it way back. I'm just on a tight schedule to make a report about this project that I was working on. I hope this is very much helpful.

Hi NightStalker,
I'd like to suggest you add an additional column into the push data step to extract and group hour values of your records. Then you can use this as a category in your chart to summarize your records with aggerate mode 'max'.

Hey thanks for the reply! I managed to push a fixed date and the shift from the ESP; However, the Earlier DAX don't work in real Time Data :S. It would've made everything easy. any suggestions.
I managed to do it; however, I can't assign the date to it, as it shows all the values. I pushed DateShift which is a unique value for every day as it contains the 3 shifts during one day, and every shift is an 8-hour interval. Funny enough, I have no idea how I can calculate the sum of the ShiftPeak.
