Different spacing between same width bars in BarChartView

[Aft3rmathpwnz]

I'm sorry for asking this question here, but is there any way to get chart like this?

X-axis here represents daily timeline (24 hours), Y-axis - time (minutes count). The idea is that every bar "grows" from x-daytime-value, when user became online, and its height (y) is time he was online. Is there no more appropriate solution than set barSpace = 0 and add 24 yVals (every is 0 except ones in which user became online)? Thanks in advance!

there is a groupSpace you can try, it defines the space between bar groups.
if you are not talking about bar groups but the time style x axis, right now it's a drawback; you have to insert some nonsense on x axis. Some people are working on the time(float) x axis. Just not have ETA yet.
