    The example shows how to create simple horizontal percent bar chart. Horizontal percent bar chart shows the data in set as percentage of
    all sets, per category.

    Creating horizontal percent bar chart is just like creating a regular \l {BarChart Example} {bar chart}, except that for a
    horizontal percent bar chart, we use QHorizontalPercentBarSeries api instead of QBarSeries. Also, in the
    \l {BarChart Example} {bar chart} we used nice numbers algorithm to make the y axis numbering look better. With
    percent bar chart there is no need for that, because the maximum y-axis value is always 100.
