Request: Add a possibility to create multiple line breaks in data line of bar chart

[annimarip]

In the line chart component it is currently possible to create multiple line breaks when using startIndex...startIndex5 and endIndex...endIndex5 props, whereas the data line in bar chart does not support that, having only startIndex and endIndex props. To be also able to display a data line with breaks in the bar chart component, lineConfigType in BarChart should support the same amount of startIndex and endIndex props as in the line chart.
