## create trend line from maximum to zero line chart

Hi Team,

Can any one help me to get a line from maxim value to Zero on Power Bi Chart.

Here is my requirement, I have a column with dates on X-Axis and Values in Y-AXIS. As shown the image below, top Graph shows my values from a column (Caluculated values, Those are good.) But We got another requirement from Client, saying that we need a trend line from Starting date to Specific Date (This will be specific, This can be anything hardcoded and can be changed.)

I have tried to split the difference and caluculated weekly values (Like date difference is 7 weeks, then caluaculate difference and based on the current date substact from max value). It was worked initially. But as there is few dates missig in the interval, it is failed and graph is not coming as stright line,

Can anyone help me on this.

Hi @sureshpydi.  Try this out:

```Trend Points =
VAR __MinDate =
MINX ( ALL ( Sheet1 ), Sheet1[Date] )
VAR __MinValue =
LOOKUPVALUE ( Sheet1[Value], Sheet1[Date], __MinDate )
VAR __MaxDate =
MAXX ( ALL ( Sheet1 ), Sheet1[Date] )
VAR __MaxValue =
LOOKUPVALUE ( Sheet1[Value], Sheet1[Date], __MaxDate )
RETURN
IF (
CALCULATE ( MIN ( Sheet1[Date] ) ) = __MinDate,
__MinValue,
IF ( CALCULATE ( MAX ( Sheet1[Date] ) ) = __MaxDate, __MaxValue, BLANK () )
)```

You'll have to be sure to set the X-axis as "Continuous" instead of "Categorical" or you will only get the starting and ending points.  Also, depending on your actual data set, the "ALL" function might have to be tweaked (using KEEPFILTERS or the like).

Hope this helps,

HI @sureshpydi,

Nope, you can't manually control analyse trend line, it is managed by power bi itself and generated based on data trend.(it not contains options allow you to customize on it)

Using the Analytics pane in Power BI Desktop

Hi Xiaoxin Sheng,

Thanks for the reply. I have tried this. But it was not worked for me. I need a line from Max to 0 using DAX query. Could you please let me know if it is possible with DAX?

Thanks,

Suresh
