How to get right percentages in line chart with legend?

[PowerRon]

Hi,

I have this line chart showing the legend by numbers. Works fine

But now I want it to show percentages instead of numbers. So what is the percentage of each legend-item each month?
I tried this

waarde =

VAR _waarde1 = [Number of Transactions]

VAR _waarde2 = CALCULATE([Number of Transactions], ALLSELECTED('Transactions Clearing Issuing'[Network Type Code]))

RETURN DIVIDE(_waarde1,_waarde2)

giving me this

And I  tried this

waarde =

VAR _waarde1 = [Number of Transactions]

VAR _waarde2 = CALCULATE([Number of Transactions], ALLEXCEPT('Calendar Local Date', 'Calendar Local Date'[Year], 'Calendar Local Date'[Month Short ENG Name]))

RETURN DIVIDE(_waarde1,_waarde2)

giving me this

In both solutions each month each lengend-item is 100%. What am I doing wrong?

Regards
Ron

Hmm, now it is fluctuating between 99 and 101%. So be it. It's OK. Thnx for helping Felix

@MFelix you solved it. Thnx. 

One more question. I only select the three network types, mentioned in the legend, in the visual. 
Each month tehy sum up between 98 and 99,5%. Never 100%. Any idea what is the cause?

Because you look for all the networks and not only the 3 you select redo the metric to this one:

waarde =

VAR _waarde1 = [Number of Transactions]

VAR _waarde2 = CALCULATE([Number of Transactions], ALLSELECTED(Table[Network Type Code]))

RETURN DIVIDE(_waarde1,_waarde2)

Hi @PowerRon ,

You need to do the calculation based on the full network type and not on the months try something similar to this:

waarde =

VAR _waarde1 = [Number of Transactions]

VAR _waarde2 = CALCULATE([Number of Transactions], REMOVEFILTERS(Table[Network Type Code]))

RETURN DIVIDE(_waarde1,_waarde2)
