Growth Rate Trend

Hello Exparts,

I am trying to make a growth trend analysis, but unable to get that. Issue is pritty similar to this issue. 
I have a Calendar Table and Sales Table. My Sample Duration is 24 months. Example, Jan2017 till Dec2018. Calendar table contains all 730 days. My Sales Table has Daily sales data. Now I need to project a 6 months Trend Chart with MOM growth.

I need to use a Month Slicer, to select month (Jan 2018, Feb 2018 or Any) that is fixed single selection only and plot below points;
1. Selected Months Sales Volume($ value)
2. Previous Months Sales Volumn ($ Value)
3. Growth Rate (%) = (Selected Month Sales Volume - Previous Months Sales Volumn) / Previous Months Sales Volumn
4. Growth Rate Trend Line Chart > A Bar Chart to project Last 6 months Growth Rate.

I have tryed some tricks from other guru's blog,
Like,
1. Previous Months Sales Volumn ($ Value) = CALCULATE (SUM('Sales Table'[Selected Months Sales Volume]),PREVIOUSMONTH('Calendar'[Calendar Date]))
2. Growth Rate (%) =
VAR _CurrentMonthVolume = SUM('Sales Table'[Selected Months Sales Volume])
VAR _LastMonthVolume = 'Sales Table'[Previous Months Sales Volumn]
VAR _Diff = _CurrentMonthVolume - _LastMonthVolume
RETURN
DIVIDE(_Diff,_LastMonthVolume,0)
3. Growth Rate Trend = CALCULATE ('Sales Table'[Growth Rate (%)],DATESINPERIOD ( 'Calendar'[Calendar Date], MAX ( 'Calendar'[Calendar Date] ),-6, MONTH ))

Unfortunately, Nothing is working while plotting these No. in a table. Growth Trend is showing all 100% and 0%. but in Card all Numbers are comming correct.

Below is the Sample Pipe delimited ( | ) Date
