A box plot series acts as a container for box-and-whiskers items. Items from multiple series are grouped into categories according to their index value.
The QBarCategoryAxis class is used to add the categories to the chart's axis. Category labels have to be unique. If the same category label is defined for several box-and-whiskers items, only the first one is drawn.

bool | boxOutlineVisible () |
void | setBoxOutlineVisible (bool visible ) |
通知程序信号:
void | boxOutlineVisibilityChanged () |
This property holds the width of the box-and-whiskers item. The value indicates the relative width of the item within its category. The value can be between 0.0 and 1.0. Negative values are replaced with 0.0 and values greater than 1.0 are replaced with 1.0.

QBoxPlotSeries::
~QBoxPlotSeries
()
Removes the series from the chart.
Adds a single box-and-whiskers item specified by
set
to the series and takes ownership of it. If the item is null or it already belongs to the series, it will not be appended. Returns
true
if appending succeeded.
Adds a list of box-and-whiskers items specified by
sets
to the series and takes ownership of them. If the list is null or the items already belong to the series, it will not be appended. Returns
true
if appending succeeded.
Returns a list of box-and-whiskers items in a box plot series. Keeps the ownership of the items.
Removes all box-and-whiskers items from the series and permanently deletes them.
Returns the number of box-and-whiskers items in a box plot series.
注意: getter 函数对于特性 count。
Inserts a box-and-whiskers item specified by
set
to a series at the position specified by
index
and takes ownership of the item. If the item is null or already belongs to the series, it will not be appended. Returns
true
if inserting succeeds.
Removes the box-and-whiskers item specified by
set
from the series and permanently deletes it if the removal succeeds. Returns
true
if the item was removed.
Takes the box-and-whiskers item specified by set from the series. Does not delete the item.
注意: The series remains the item's parent object. You must set the parent object to take full ownership.
返回
true
若 take 操作成功。
