In this example, a very simple pie chart is created demonstrating the basic steps in creating pie charts.
[The following project is available in "cppdemo/simplepie".]
#include "chartdir.h"
int main(int argc, char *argv[])
{
//The data for the pie chart
double data[] = {25, 18, 15, 12, 8, 30, 35};
//The labels for the pie chart
const char *labels[] = {"Labor", "Licenses", "Taxes", "Legal", "Insurance",
"Facilities", "Production"};
//Create a PieChart object of size 360 x 300 pixels
PieChart *c = new PieChart(360, 300);
//Set the center of the pie at (180, 140) and the radius to 100 pixels
c->setPieSize(180, 140, 100);
//Set the pie data and the pie labels
c->setData(DoubleArray(data, sizeof(data)/sizeof(*data)), StringArray(
labels, sizeof(labels)/sizeof(*labels)));
//output the chart
c->makeChart("simplepie.png");
//free up resources
delete c;
return 0;
