HorizontalBarChart Example▲

QHorizontalBarChart shows the data in sets as separate bars, which are grouped in categories. QHorizontalBarChart works just like QBarChart, except that the bars are drawn horizontally on the chart.

Creating Horizontal Bar Charts▲

The bar sets are used in the same way in all bar charts. To illustrate the difference between various bar charts, we use the same data in all examples. Data that bar chart visualizes, is defined by QBarSet instances. Here we create the sets and append data to them. The data is appended here with << operator. Alternatively, the append method could also be used.

    QBarSet *set0 = new QBarSet("Jane");
    QBarSet *set1 = new QBarSet("John");
    QBarSet *set2 = new QBarSet("Axel");
    QBarSet *set3 = new QBarSet("Mary");
    QBarSet *set4 = new QBarSet("Samantha");

    *set0 &lt;&lt; 1 &lt;&lt; 2 &lt;&lt; 3 &lt;&lt; 4 &lt;&lt; 5 &lt;&lt; 6;
    *set1 &lt;&lt; 5 &lt;&lt; 0 &lt;&lt; 0 &lt;&lt; 4 &lt;&lt; 0 &lt;&lt; 7;
    *set2 &lt;&lt; 3 &lt;&lt; 5 &lt;&lt; 8 &lt;&lt; 13 &lt;&lt; 8 &lt;&lt; 5;
    *set3 &lt;&lt; 5 &lt;&lt; 6 &lt;&lt; 7 &lt;&lt; 3 &lt;&lt; 4 &lt;&lt; 5;
    *set4 &lt;&lt; 9 &lt;&lt; 7 &lt;&lt; 5 &lt;&lt; 3 &lt;&lt; 1 &lt;&lt; 2;

We create the series and append the bar sets to it. The series takes ownership of the barsets. The series groups the data from sets to categories. The first values of each set are grouped together in the first category; the second values in the second category, and so on.

 
Sélectionnez
    QHorizontalBarSeries *series = new QHorizontalBarSeries();
    series-&gt;append(set0);
    series-&gt;append(set1);
    series-&gt;append(set2);
    series-&gt;append(set3);
    series-&gt;append(set4);

Here we create the chart object and add the series to it. We set the title for chart with setTitle and then turn on animations of the series by calling setAnimationOptions(QChart::SeriesAnimations).
