Metrics working on a table but not in chart

[GuillaumeD]

Hello everyone, 

I have a reporting with some metrics, i have some issue with one of them, i can use it in a table but in chart i can only use it as "tooltip" (info-bulle in french)

here an example of table

here if i swap to a chart 

here my metrics : 

DMC_Chat =

var vSeconds= (CALCULATE(SUM(Interactions[Heure_dmc_phone]),Interactions[Media Type]="Message",Interactions[Agent Name]<>"")*3600+CALCULATE(SUM(Interactions[Minute_DMC]),Interactions[Media Type]="Message",Interactions[Agent Name]<>"")*60+CALCULATE(SUM(Interactions[Second_DMC]),Interactions[Media Type]="Message",Interactions[Agent Name]<>""))/CALCULATE(count(Interactions[Conversation Id]),Interactions[Media Type]="Message",Interactions[Agent Name]<>"")

var vMinutes=int( vSeconds/60)

var vRemainingSeconds=MOD(vSeconds, 60)

var vHours=INT(vMinutes/60)

var vRemainingMinutes=MOD(vMinutes,60)

return

  time(vHours,vRemainingMinutes,vRemainingSeconds)

i tried manythings, change metrics main table, other calendar data, checked on google

I can't put the metrics in Y or X even alone (it's the same with all chart form) 

i have other time metrics with the same code, they are not working too, maybe it's about my formula ?

Can you help me with this

regards
