Hello Community,
I am trying to visualize an inclinometer chain composed of 20 sensors.
I receive the data every hour and I have to visualize a comparison (difference of values) of every measurement with a reference measurement that can be chosen dynamically.
Every ONE measurement is composed of 40 rows, depending on the depth and the direction A or B.
All 40 rows are to be recognized by the same measurement date and time... This is how a measurement is defined.
As a first step. I have fixed a reference measurement by adding a column called reference_measurment which is equal to 1 in the rows to be considered for this reference measurement and is then 0 elsewhere.
I have created a quick measure as follows:
Average of value difference from 1 =
VAR __BASELINE_VALUE =
CALCULATE(
AVERAGE('Inklinometer (2)'[value]),
'Inklinometer (2)'[reference_measurement] IN { 1 }
)
VAR __MEASURE_VALUE = AVERAGE('Inklinometer (2)'[value])
RETURN
IF(NOT ISBLANK(__MEASURE_VALUE), __MEASURE_VALUE - __BASELINE_VALUE)
On the graph I see that the measure applies only for one measurement which is actually the reference one => I get 0 everywhere. But it does not work for the other values of the column (other values of other measurements).
I think it might have to do that power BI cannot sort the values in the right order to be able to calculate the requested measure... I don't know how I can sort, or order or give a condition saying where the baselinevalue[depth] = measurevalue[depth]...
can someone help me?
Then I need to solve the problem of being able to visualize the measure values on my x-axis and not on the y-axis.
and then I need to figure out how I can choose the reference measurement dynamically...
I will really appreciate some help!
Thank you in advance.
Best regards,
Yushi
