This example extends the
Simple Bar Chart example by introducing three more features of ChartDirector:
[The following project is available in "cppdemo/threedbar".]
#include "chartdir.h"
int main(int argc, char *argv[])
{
//The data for the bar chart
double data[] = {85, 156, 179.5, 211, 123};
//The labels for the bar chart
const char *labels[] = {"Mon", "Tue", "Wed", "Thu", "Fri"};
//Create a XYChart object of size 300 x 280 pixels
XYChart *c = new XYChart(300, 280);
//Set the plotarea at (45, 30) and of size 200 x 200 pixels
c->setPlotArea(45, 30, 200, 200);
//Add a title to the chart
c->addTitle("Weekly Server Load");
//Add a title to the y axis
c->yAxis()->setTitle("MBytes");
//Add a title to the x axis
c->xAxis()->setTitle("Work Week 25");
//Add a bar chart layer with green (0x00ff00) bars using the given data
c->addBarLayer(DoubleArray(data, sizeof(data)/sizeof(*data)), 0xff00
)->set3D();
//Set the x axis labels using the given labels
c->xAxis()->setLabels(StringArray(labels, sizeof(labels)/sizeof(*labels)));
//output the chart
c->makeChart("threedbar.png");
//free up resources
delete c;
return 0;
