title: QtCharts in Qt 5.6
body: <p>I want to use QtCharts inside Qt 5.6. (I have no plans to install Qt 5.7/5.8 in the next months). Although I've found a Blog on the Qt site where Qt Charts add-in for At 5.6 is presented I did not find a download link. Has anyone any idea how to download Qt Charts lib and how to embed it inside Qt 5.6?</p>
