Description:
BarChartPlotter is a simple Bar Chart plotting widget.
This is a technical preview only - BarChartPlotter will be included into QSint::Charts library.
BarChartPlotter provides easy-to-use API and performs fast "native" painting (directly via QPainter).
Currently it allows to draw Bar Charts of 2 types: Stacked and Column.
BarChartPlotter follows MVC ideology using QAbstractItemModel as data source.

Hello! Many thanks for this project. :) My question: i try to colorize the separate items of the chart, for example: itemModel->setData(itemModel->index(i, j), Qt::red, Qt::BackgroundRole); or itemModel->setData(itemModel->index(i, j), Qt::blue, Qt::ForegroundRole); and the objects are not colorized. what is wrong? thank you!
all right, i solved it. replaced in BarChartPlotter::drawContent // QPen pen(qvariant_cast<QColor>(m_model->headerData(j, Qt::Vertical, Qt::ForegroundRole))); // QBrush brush(qvariant_cast<QBrush>(m_model->headerData(j, Qt::Vertical, Qt::BackgroundRole))); QPen pen(qvariant_cast<QColor>(m_model->data(m_model->index(j,i), Qt::ForegroundRole))); QBrush brush(qvariant_cast<QBrush>(m_model->data(m_model->index(j,i), Qt::BackgroundRole))); this solution i need for colorized displaing of percent information, f. ex: about 35% is red and so on
