\title GroupedBarChart Example | ||||
\subtitle | ||||
The example shows how to create simple bar chart. GroupedBarChart shows the data in sets as separate bars, which are grouped in categories. | ||||
\image examples_groupedbarchart.png | ||||
First we define categories. | ||||
\snippet ../examples/groupedbarchart/main.cpp 1 | ||||
Data that groupedbarchart visualizes, is defined by QBarSet instances. Here we create some sets and append data | ||||
we want to visualize to them. | ||||
\snippet ../examples/groupedbarchart/main.cpp 2 | ||||
To combine the sets and categories to a chart, we need to create QBarSeries instance. When creating | ||||
the QBarSeries, the categories must be known. Sets can be added later. For example purposes the sets | ||||
are added to series here. | ||||
\snippet ../examples/groupedbarchart/main.cpp 3 | ||||
Then we create a chart and add the series to it. | ||||
\snippet ../examples/groupedbarchart/main.cpp 4 | ||||
And we also want to show the legend, so that the data is easier to read. | ||||
\snippet ../examples/groupedbarchart/main.cpp 5 | ||||
Finally we add the chart onto a view. | ||||
\snippet ../examples/groupedbarchart/main.cpp 6 | ||||
And it is ready to be shown in a window. | ||||
\snippet ../examples/groupedbarchart/main.cpp 7 | ||||
