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);
}

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);

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. ;)
