Looking for chart library that allows multiple x axis, and allows those xaxis to be displayed both at top and bottom, in a way that top xaxis groups multiple bottom xaxis steps into one group. To illustrate this I created simple sketch for what I am searching for:
Like on image, top xaxis with the name of [B], groups multiple xaxis at the bottom: 5, 10, 30. Similarly top xasix C, groups two bottom xaxis 40, 80
Anyone knows library that can achieve this effect?
but could not find anything like this in examples, closest was chartsjs with multiple xaxis, but only on the bottom, not top. (https://jsfiddle.net/hamalainen/6c0L1yva/3/)
