Answer 1

you can hide value by 'false'

data: [[0, 0, false], [0, 1, 2], [0, 2, 3], [0, 3, 4], [0, 4, 5], [1, 0, 2], [1, 1, 4], [1, 2, 6], [1, 3, 8], [1, 4, 10], [2, 0, 3], [2, 1, 6], [2, 2, 9], [2, 3, 12], [2, 4, 15], [3, 0, 4], [3, 1, 8], [3, 2,12], [3, 3, 16], [3, 4, 20], [4, 0, 5], [4, 1, 10], [4, 2, 15], [4, 3, 20], [4, 4, 25]
