\brief Vertical model mapper for bar series.
|
|
|
|
|
|
Model mappers allow you to use QAbstractItemModel derived models as a data source for a chart series.
|
|
|
Vertical model mapper is used to create a connection between QAbstractBarSeries and QAbstractItemModel derived model object.
|
|
|
Model mapper maintains equal size of all the BarSets.
|
|
|
Adding/removing value from the BarSet causes the the same change in the rest of the BarSets added to the same series.
|
|
|
\note Used model has to support adding/removing rows/columns and modifying the data of the cells.

\brief Vertical model mapper for bar series.
|
|
|
|
|
|
VBarModelMapper allows you to use your own QAbstractItemModel derived model with data in columns
|
|
|
as a data source for any bar series. It is possible to use both QAbstractItemModel and bar
|
|
|
series data API to manipulate data. VBarModelMapper keeps the series and the model in sync.
|
|
|
|
|
|
The following QML example would create a bar series with three bar sets (assuming the model has
|
|
|
at least four columns). Each bar set would contain data starting from row 1. The name of a set
|
|
|
would be defined by the horizontal header (of the column).
|
|
|
\code
|
|
|
BarSeries {
|
|
|
VBarModelMapper {
|
|
|
model: myCustomModel // QAbstractItemModel derived implementation
|
|
|
firstBarSetColumn: 1
|
|
|
lastBarSetColumn: 3
|
|
|
firstRow: 1
|
|
|
}
