   • Use auto-width range – Use the lowest and highest values in the dataset to define the start and end values on the X-axis, respectively.
   • Range start – Value of the first bin. Only available if Use auto-width range is unchecked.
   • Range end – Value of the last bin. Only available if Use auto-width range is unchecked.
   • Bin width – Define the width of the bins. Only available if Widths is selected as the Bin type.
5. Configure the Colour section.
