Closed:how can make random color in cytoscape

Question

[Learner]

I want to make a visualisation where i show each cluster with a different color . As an example I show several nodes below

A              B     
AFD_1       DNGS_1
AFD_1       SGDH_1
DNGS_1      SGDH_1
NHYG_2      QHD_2
NHYG_2      lkd_2
NHYG_2      uyete_2
QHD_2       lkd_2
QHD_2      uyete_2
lkd_2      uyete_2
AFD_3       TTT_3

So I have those without number, with _1, with _2 and_3

I want to show each of them with separate color.

I load them as network to the cytoscape I tried to make a table showing

0
1
1
1
2
2
2
2
2
2
3

and then I load this as table

Then I go to style, and then try to change the fill color to discrete but it does not matter, the color is still the same.

How would you do this ? in a more automatic way .
