Fix misrepresented data range from grouped violin plot.
In the parallel coordinate plot, grouped violin plot uses
seaborn.violinplotand by its default it extends the density distribution to past extreme datapoints by 2 bandwidth (cuts=2parameter used by default). So in case like data value range is 0-5, then the violin distribution is shown for ~ -2 to 7.Example with dummy data [0, 1, 2, 3, 4, 5], with default setting (

cuts=2)The violin range can be limited to the actual value range by using parameter
cuts=0, as in the second attached.Example with dummy data [0, 1, 2, 3, 4, 5], with default setting (

cuts=0)
