Linear trend chart using baseline data

[manojk_pbi]

Hi,

I have tasks defined by projects at start of the year and month on month actuals will be added. Need to plot a chart to actuals in one line and another one linear trend till start of the next year (i.e Jan'25). Attached data and out snapshot for reference

The liner line needs to be configured. it could be of 6% or 8%. The measure should work on Project filter as well when applied.

MonthYear	Project	Tasks
24-Jan		250
24-Feb		251
24-Mar		220
24-Apr		220
24-May
24-Jun
24-Jul
24-Aug
24-Sep
24-Oct
24-Nov
24-Dec
25-Jan

Thanks for the reply from @lbendlin , please allow me to provide another insight: 

Hi  @manojk_pbi ,

I created some data:

Here are the steps you can follow：

1. Create calculated table.

Table 2 =
var _date=
SUMMARIZE('Table','Table'[Month],"mindate",MINX(FILTER(ALL('Table'),'Table'[Month]=EARLIER('Table'[Month])),[Date]))
return
ADDCOLUMNS(
    _date,"rank",RANKX(_date,[mindate],,ASC))

2. Select [Month] – Column tools – Sort by column – [rank].

3. Create measure.

value =
var _index=MINX(ALL('Table 2'),'Table 2'[rank])
var _month=MINX(FILTER(ALL('Table 2'),'Table 2'[rank]=_index),[Month])
var _value=
SUMX(FILTER(ALL('Table'),'Table'[Month]=_month),[Tasks])
RETURN
IF(
    MAX('Table 2'[rank])= _index,_value,
    _value-
_value * (MAX('Table 2'[rank])-1) * 0.008)

4. Result:
