Charting an Electrocardiogram from a single value

Hi All,

 

I'm trying to chart an Electrocardiogram from a  value that contains 2500 values separated by a space. My dataset looks like this:

I'm trying to create a chart with the numbers in the cell and a fixed X-axis value (let's say 2,000). My chart should look like this:

I have tried using split.text and Generate series in DAX, but since this is medical data, I want to make sure that if for some reason one data point doesn't have 2,500 points, that I don't mess up the whole thing. What could be the best way to create this graph?

 

Thanks!

Hi @Edisonsepulveda ,

According to your description, here's my solution.

Sample:

vyanjiangmsft_0-1686212193873.png

1. Replace value in Power Query. For the Value column, replace space to "|".

2.Create a calculated column.

PathNo =
PATHLENGTH ( [Value] )

3.Create a new table.

Table 2 =
GENERATESERIES ( 1, MAX ( 'Table'[PathNo] ), 1 )

4.Create a measure.

Measure =
CONVERT (
    PATHITEM ( SELECTEDVALUE ( 'Table'[Value] ), MAX ( 'Table 2'[Row] ) ),
    INTEGER
)

Put Row column in X-axis and measure in Y-axis, get the correct result.
