\brief Horizontal model mapper for bar series
|
|
|
\mainclass
|
|
|
|
|
|
Model mappers allow you to use QAbstractItemModel derived models as a data source for a chart series.
|
|
|
Horizontal 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.

\qmlclass HBarModelMapper QHBarModelMapper
|
|
|
|
|
|
HBarModelMapper allows you to use your own QAbstractItemModel derived model with data in rows as a data source
|
|
|
for any bar series. It is possible to use both QAbstractItemModel and bar series data API to manipulate data.
|
|
|
HBarModelMapper 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 rows). Each bar set would contain data starting from column 1. The name of a set would be defined by
|
|
|
the vertical header (of the row).
|
|
|
\code
|
|
|
BarSeries {
|
|
|
HBarModelMapper {
|
|
|
model: myCustomModel // QAbstractItemModel derived implementation
|
|
|
firstBarSetRow: 1
|
|
|
lastBarSetRow: 3
|
|
|
firstColumn: 1
|
|
|
}
|
|
|
}
