[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; }
