Qt Charts is an add-on that comes with the Qt Enterprise product. Qt Charts provides easy to use API to create stunning Line, Spline, Area, Scatter, Pie and Bar charts. Qt Charts works seamlessly with Qt 5, Qt 4.8 and the latest 4.7 releases. You can use Qt Charts with both C++ and Qt Quick according to you preference.
Qt Charts Functionality
There is a big demand for visually pleasing charts in modern user interfaces. We have designed Qt Charts to meet the needs for creating interactive chart based user interfaces – in addition to showing static data in a chart component. To address these needs we have made the components versatile and extendable. See the Qt Charts documentation here.
Developing a single chart type for a single use case with Qt is relatively easy. Qt offers good drawing and data model API’s. However such custom components might be difficult to expand to support several use cases and of course they increase the maintenance burden for application developers. Developing an extendable charting library requires several man months of implementation work and finding the correct chart presentation always requires a lot of implementation before seeing results in action.
In June 2013 we released Charts 1.3.0 which brings Polar and Boxplot charts and some API enhancements. This release brings also official Qt 5 support for Widget based applications and QML applications by using Qt Quick 2 add-on module. As usual the package is available in the Customer Portal.
