Multiple scatter chart.

Hello,

I would like to plot on te same scatter chart points from different tables.

Basically I want :

Table 1 :

X; Y; ColorBoolean

Table 2 :

X'; Y'

with the dot from table 2 being another color than these of the table 1 's dots.

Do you have any idea how is thiss possible ? Is there an appropriate Custom Visual ? 

Thanks !
