3D Scatter Chart (1)

This example demonstrates the basic steps in creating 3D scatter charts.

Create a ThreeDScatterChart object using ThreeDScatterChart.ThreeDScatterChart.
Specify the position and size of the plot region using ThreeDChart.setPlotRegion.
Add a scatter group to the chart using ThreeDScatterChart.addScatterGroup. In this example, the symbol color is set to SameAsMainColor, which means the color depends on the z-coordinate as according to the color axis (color legend). The color axis can be accessed using ThreeDChart.colorAxis.
Set the position of the color axis (the color legend) using ThreeDChart.setColorAxis.
Add chart and axis titles using BaseChart.addTitle and Axis.setTitle.
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).

The following is the command line version of the code in "cppdemo/threedscatter". 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 XYZ data for the 3D scatter chart as 3 random data series
    RanSeries* r = new RanSeries(0);
    DoubleArray xData = r->getSeries(100, 100, -10, 10);
    DoubleArray yData = r->getSeries(100, 0, 0, 20);
    DoubleArray zData = r->getSeries(100, 100, -10, 10);

    // Create a ThreeDScatterChart object of size 720 x 600 pixels
    ThreeDScatterChart* c = new ThreeDScatterChart(720, 600);

    // Add a title to the chart using 20 points Times New Roman Italic font
    c->addTitle("3D Scatter Chart (1)  ", "Times New Roman Italic", 20);

    // Set the center of the plot region at (350, 280), and set width x depth x height to 360 x 360
    // x 270 pixels
    c->setPlotRegion(350, 280, 360, 360, 270);

    // Add a scatter group to the chart using 11 pixels glass sphere symbols, in which the color
    // depends on the z value of the symbol
    c->addScatterGroup(xData, yData, zData, "", Chart::GlassSphere2Shape, 11, Chart::SameAsMainColor
        );

    // Add a color axis (the legend) in which the left center is anchored at (645, 270). Set the
    // length to 200 pixels and the labels on the right side.
    c->setColorAxis(645, 270, Chart::Left, 200, Chart::Right);

    // Set the x, y and z axis titles using 10 points Arial Bold font
    c->xAxis()->setTitle("X-Axis Place Holder", "Arial Bold", 10);
    c->yAxis()->setTitle("Y-Axis Place Holder", "Arial Bold", 10);
    c->zAxis()->setTitle("Z-Axis Place Holder", "Arial Bold", 10);

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

    //free up resources
    delete r;
    delete c;

    return 0;
