Wt

Hi,

I have a vector that I'm trying to display in a WCartesionChart, and it seems like Wt is crashing on me.

Can some one quickly show me how to display a vector of data in a Line WCartesioChart?

This is what I'm doing...

    mCPUGraph  = new Wt::Chart::WCartesianChart() ;
    std::unique_ptr<Wt::Chart::WCartesianChart> cpugraph(mCPUGraph) ;
    mCPUGraph->setStyleClass("graph") ;
    mCPUGraph->setTitle("CPU") ;

    slayout->addWidget(std::move(cpugraph), 1, 0) ;

Then in a timer event

                std::shared_ptr<Wt::WAbstractItemModel> model = std::make_shared<Wt::WStandardItemModel>(0, 0) ;

                for(size_t sloop = 0; sloop < mCpuSeries.size(); sloop++)
                {
                    if(sloop > model->rowCount())
                    {
                        model->insertRows(model->rowCount(), 1) ;
                    }
                    model->setData(sloop, 0, dominfo[dloop].cpupercent) ;
                }

                mCPUGraph->setModel(model) ;
                mCPUGraph->setXSeriesColumn(0) ;
                mCPUGraph->setLegendEnabled(true) ;
                mCPUGraph->setZoomEnabled(true) ;
                mCPUGraph->setPanEnabled(true) ;
                mCPUGraph->setAutoLayoutEnabled(true) ;
                mCPUGraph->setType(Wt::Chart::ChartType::Scatter) ;
                mCPUGraph->axis(Wt::Chart::Axis::X).setScale(Wt::Chart::AxisScale::Date) ;

                auto series = std::make_unique<Wt::Chart::WDataSeries>(0, Wt::Chart::SeriesType::Line);
                series->setShadow(Wt::WShadow(3, 3, Wt::WColor(0, 0, 0, 127), 3));
                mCPUGraph->addSeries(std::move(series));

Thanks,
Gerald
