Can you tell me how to turn on the Legend for your example "ScrollApplication1'? |

There is no simple toggle to turn on a legend. Legends must be built using the StandardLegend class. Use of that class is described in the QCChart2D Charting manual. All of the examples using it are found in the Quinn-Curtis\DotNet\QCChart2D\Visual CSharp\Examples folder (or Quinn-Curtis\DotNet\QCChart2D\Visual Basic\Examples for VB). A simple example for the ScrollApplication1 program would be:
// Horizontal Legend at bottom
Font legendFont = new Font("SansSerif", 12, FontStyle.Bold);
ChartAttribute legendAttributes = new ChartAttribute(Color.Black, 1, 0);
legendAttributes.SetLineFlag(false);
StandardLegend legend = new StandardLegend(0.1, 0.95, 0.7, 0.3, legendAttributes, StandardLegend.HORIZ_DIR);
legend.AddLegendItem("Temp 1", ChartObj.LINE, lineplot1, legendFont);
legend.AddLegendItem("Temp 2", ChartObj.LINE, lineplot2, legendFont);
chartVu.AddChartObject(legend);
or
// Vertical Legend in upper right
Font legendFont = new Font("SansSerif", 12, FontStyle.Bold);
ChartAttribute legendAttributes = new ChartAttribute(Color.Black, 1, 0);
legendAttributes.SetLineFlag(false);
StandardLegend legend = new StandardLegend(0.8, 0.15, 0.3, 0.3, legendAttributes, StandardLegend.VERT_DIR);
legend.AddLegendItem("Temp 1", ChartObj.LINE, lineplot1, legendFont);
legend.AddLegendItem("Temp 2", ChartObj.LINE, lineplot2, legendFont);
chartVu.AddChartObject(legend); |
