Issue with Line chart -- Change count of to actual value

[panks]

I have very basic data set with 3 cols -- date time stamp and 2 temparatures fields defined as decimal number. 

I want to display the variance in temps agains timestamps in a line chart but when I try to use temp on y axis it always shows count of rather than acutal values.  The data type of timestamp is date time which temp is decimal. 

Kindly help solve this.

Hi @panks ,

Just change the aggregation to SUM, since you only have one value for each timestamp you will get the correct value.
