Selecting line graph

Hi there,


I am calculating the half-hourly average value using the following measure:

Average power = Average(Table[Power])


and plot the information in a line chart:



The x-axis contains the time stamp and the y-axis contains the consumption. I want a selection option on the line chart as shown in the following picture (grey area):



So that when I select the certain area of a line chart, it gives the difference between the start and end time of the x-axis and also add up the consumption of the selected area. 

I have no idea how to do that. Any help would be really appreicated.

@leo_89 , With selection you can zoom, I doubt you can get diff.  Try this in tooltip


but measure like this can help

var _max1 = maxx(allselected('Date'), Date[Date])
var _min1 = minx(allselected('Date'), Date[Date])
calculate([measure], filter('Date', 'Date'[Date] =_max1)) -calculate([measure], filter('Date', 'Date'[Date] =_min1))

@amitchandak , how do you define [measure]?

Hi @leo_89 ,


Based on my understanding, the [measure] in the expression of @amitchandak stands for your meausre [Average power].
