Pie Chart Implementation

[Eleasar]

Chart Info: http://www.ics.com/files/qtdocs/itemviews-chart.html

I have copied Pieview.h and .cpp. I keep my data in a vector, so don't need chart.qrc.

My Abstract Model def:

absModel = new QStandardItemModel(8, 2, this);
    absModel->setHeaderData(0, Qt::Horizontal, tr("Age"));
    absModel->setHeaderData(1, Qt::Horizontal, tr("Gender"));
 
    for(int row=0; row<myFace.size(); row++){
        absModel->setData(absModel->index(row, 0, QModelIndex()),
                       myFace.at(row).age);
        absModel->setData(absModel->index(row, 1, QModelIndex()),
                       myFace.at(row).gender);
    }

absModel = new QStandardItemModel(8, 2, this);
    absModel->setHeaderData(0, Qt::Horizontal, tr("Age"));
    absModel->setHeaderData(1, Qt::Horizontal, tr("Gender"));

    for(int row=0; row<myFace.size(); row++){
        absModel->setData(absModel->index(row, 0, QModelIndex()),
                       myFace.at(row).age);
        absModel->setData(absModel->index(row, 1, QModelIndex()),
                       myFace.at(row).gender);
    }

To copy to clipboard, switch view to plain text mode 

Both "age" and "gender" contain integer values. I want to show that with 2 pie charts. One of them show Ages and other one shows genders. (0:male 1:female)

ViewSetup:

QTableView *table = new QTableView;
    QListView *list = new QListView;
    agePieChart = new PieView;
    genderPieChart = new PieView;
    ui->splitter->addWidget(list);
    ui->splitter->addWidget(table);
    ui->splitter->addWidget(agePieChart);
    ui->splitter->addWidget(genderPieChart);
    ui->splitter->setStretchFactor(0, 0);
    ui->splitter->setStretchFactor(1, 1);
 
    table->setModel(absModel);
    list->setModel(absModel);
    agePieChart->setModel(absModel);
    genderPieChart->setModel(absModel); 
    QItemSelectionModel *selectionModel = new QItemSelectionModel(absModel);
    table->setSelectionModel(selectionModel);
    list->setSelectionModel(selectionModel);
    agePieChart->setSelectionModel(selectionModel);
    genderPieChart->setSelectionModel(selectionModel);
    QHeaderView *headerView = table->horizontalHeader();
    headerView->setStretchLastSection(true);

QTableView *table = new QTableView;
    QListView *list = new QListView;
    agePieChart = new PieView;
    genderPieChart = new PieView;
    ui->splitter->addWidget(list);
    ui->splitter->addWidget(table);
    ui->splitter->addWidget(agePieChart);
    ui->splitter->addWidget(genderPieChart);
    ui->splitter->setStretchFactor(0, 0);
    ui->splitter->setStretchFactor(1, 1);

    table->setModel(absModel);
    list->setModel(absModel);
    agePieChart->setModel(absModel);
    genderPieChart->setModel(absModel); 
    QItemSelectionModel *selectionModel = new QItemSelectionModel(absModel);
    table->setSelectionModel(selectionModel);
    list->setSelectionModel(selectionModel);
    agePieChart->setSelectionModel(selectionModel);
    genderPieChart->setSelectionModel(selectionModel);
    QHeaderView *headerView = table->horizontalHeader();
    headerView->setStretchLastSection(true);

That code shows ListView and TableView in splitter but Charts are blank page.

Have you had a look at the code?

As far as I can tell the pie view expects column 0 to be a color and column 1 to be the value of the segment.

I have adapted my code to example, and it worked.
