Wt

Hello,

I am trying to implement a scatterplot. However, I can see the (screenshot attached), but not the curve lines. The server console is not showing up any errors. Here is my code as below:

Wt::WWidget* ChartExp::ChartView(Wt::WContainerWidget* w){

Wt::WContainerWidget* c = new Wt::WContainerWidget(w);
Wt::WStandardItemModel* model = new Wt::WStandardItemModel(c);
for (int row = 0; row < 100; row++)

{
model->setData(row, 0, row);
model->setData(row, 1, row*2);
}

@

Wt::Chart::WCartesianChart *chart = new Wt::Chart::WCartesianChart();

chart->setBackground(Wt::WColor(220, 220, 220));

chart->setModel(model);

chart->setXSeriesColumn(1);

chart->setLegendEnabled(true);

chart->setType(Wt::Chart::ScatterPlot);@

Wt::Chart::WDataSeries y_series(2, Wt::Chart::LineSeries);
y_series.setShadow(Wt::WShadow(3, 3, Wt::WColor(0, 0, 0, 127), 3));
chart->addSeries(y_series);
chart->resize(800, 300);
chart->setMargin(Wt::WLength::Auto, Wt::Left | Wt::Right);
return chart;
}

Am I missing something? In the 'Examples' files of Scatter plot I see a file 'ChartConfig.h' and 'ChartConfig.c', but on the widgetGallery webpage (http://www.webtoolkit.eu/widgets/graphics-charts/scatter-plot), I don't see that config details.

Thanks
