@impulsi,
It is possible in Range Bar Chart to have more than one bar for each y-axis value?
Incase of range-bar chart, x-axis is placed vertically and y-axis horizontally. Do you mean same x-value? If so, you can achieve it by passing same x-value for multiple datapoints as shown in this JSFiddle.
If this doesn’t help you fulfill your requirements, can you kindly share pictorial representation or an example of your requirements & brief us further so that we can understand it better and help you out?
