Simple Pyramid Chart

This example demonstrates the basic steps in creating pyramid charts.

Create a PyramidChart object using PyramidChart.PyramidChart.
Specify the center and radius of the pie using PyramidChart.setPyramidSize.
Specify the data used to draw the pie using PyramidChart.setData.
Add labels at the center of the pyramid layers using PyramidChart.setCenterLabel
Pass the chart to the CChartViewer for display using CChartViewer.setChart (MFC version) or QChartViewer.setChart (Qt version), or generate the chart as an image file using BaseChart.makeChart (Command Line version).
Generate tool tips for the chart using BaseChart.getHTMLImageMap. (MFC/Qt version)

The following is the command line version of the code in "cppdemo/simplepyramid". The MFC version of the code is in "mfcdemo/mfcdemo". The Qt Widgets version of the code is in "qtdemo/qtdemo". The QML/Qt Quick version of the code is in "qmldemo/qmldemo".

#include "chartdir.h"

int main(int argc, char *argv[])
{
    // The data for the pyramid chart
    double data[] = {156, 123, 211, 179};
    const int data_size = (int)(sizeof(data)/sizeof(*data));

    // The labels for the pyramid chart
    const char* labels[] = {"Funds", "Bonds", "Stocks", "Cash"};
    const int labels_size = (int)(sizeof(labels)/sizeof(*labels));

    // Create a PyramidChart object of size 360 x 360 pixels
    PyramidChart* c = new PyramidChart(360, 360);

    // Set the pyramid center at (180, 180), and width x height to 150 x 180 pixels
    c->setPyramidSize(180, 180, 150, 300);

    // Set the pyramid data and labels
    c->setData(DoubleArray(data, data_size), StringArray(labels, labels_size));

    // Add labels at the center of the pyramid layers using Arial Bold font. The labels will have
    // two lines showing the layer name and percentage.
    c->setCenterLabel("{label}\n{percent}%", "Arial Bold");

    // Output the chart
    c->makeChart("simplepyramid.png");

    //free up resources
    delete c;

    return 0;
