Hi, I'd like to create a line graph with kibana

here is my log csv :

2018-07-06 10:32:52;Q34QRM;ICaYoB;MSC_MTC;Y1;X1

2018-07-06 10:32:52;uRtEg6;ICaYoB;MSC_MTSMS;Y1;X2

2018-07-06 10:32:52;YCKCRq;ICaYoB;MSC_MOSMS;Y1;X3

2018-07-06 10:32:52;F12r6L;ACaYoA;MSC_MTC;Y2;X4

2018-07-06 10:32:52;ulOEpY;ACaYoA;MSC_MTSMS;Y2;X5

2018-07-06 10:32:53;tP04qj;ACaYoA;MSC_MOSMS;Y2;X6

Y : nb data in and X: nb data out

I'd like to get something like :

data_in = Y1+Y2 not Y1+Y1+Y1+Y2+Y2+Y2

data_out = X1+X2+X3+....+Xn
