How to use

1. Declare a CScrollChart object — it’s a template you must use to specify a type of data.

CScrollChart< float > m_wndChart;

2. Use Create (See help file for values).

m_wndChart.Create( WS_VISIBLE | GS_NOTIFY,
                        rectChart,
                        this,
                        IDR_CHART);

3. Add lines.

m_wndChart.AddLine(ID_LINE1, RGB(255,0,0));
…
m_wndChart.AddLine(ID_LINE2, RGB(0,0,255), LS_POINT | LS_HORZAUTO);

You can add new lines at any moment.

4. Add data to line.

m_wndChart.AddData(ID_LINE1, 3, 9);
…
m_wndChart.AddData(ID_LINE1, 10, 2);
m_wndChart.AddData(ID_LINE2, 3);
m_wndChart.AddData(ID_LINE2, 5);

m_wndChart.AddData(ID_LINE2, 34);
