\section1 Using setBarSelected()
We create the sets and fill them with the data. Then we create a series and append data to it.
\snippet selectedbar/main.cpp 1
We create the chart and add series to it.
Also, we add a title to the chart, set animation for the chart, and align the legend.
\snippet selectedbar/main.cpp 2
Here we set the color for the selected bars.
\snippet selectedbar/main.cpp 3
Next step is adding axes:
QBarCategoryAxis for years of measurements and QValueAxis for values range.
\snippet selectedbar/main.cpp 4
Then we add the chart view to put the chart in.
\snippet selectedbar/main.cpp 5
Here we create a widget for labels of values of selected and unselected bars.
\snippet selectedbar/main.cpp 6
We connect selecting of a specific bar with labels of values using a lambda.
\c {set->toggleSelection({index})} sets the bar selected.
\snippet selectedbar/main.cpp 7
Finally, we create the main widget and add other layouts to it and run the application.
