Draw a line graph

How to programming a line graph with SIC Draw module.

Using assembly SIC.Draw

This topic contains the following sections:

Project example easyPlan create a characteristic curve.

There are two possibilities implement SIC.Draw object. Implement SIC.Draw as a object or implement SIC.Draw as inherited to class.

This example implemented as a object because not need a refrence to SIC.Draw in the user interface (only in the logic layer).

SIC Draw assembly implementation

  1. Add Reference SIC.Draw in the project

  2. Create a class with line graph object

    C#
    Copy
    /// <summary>
/// Anlagekennlinie Chart
/// </summary>
/// <remarks>
/// Using assembly reference: SIC.Draw
/// </remarks>
public class AnlagekennlinieChart
{
    /// <summary>
    /// Constructor without parameter
    /// </summary>
    public AnlagekennlinieChart() { }

    /// <summary>
    /// Anlagekennlinie Grafik
    /// </summary>
    private SIC.Draw.LineChart Chart { get; set; }

}

Is it finished? Then it can already a draw a graphic.

Create method that create a line chart graphic.

  • C#
    Copy
    /// <summary>
/// Create a new Anlagekennlinie chart.
/// </summary>
/// <remarks>
/// Chart save as a JPEG image file.
/// </remarks>
/// <param name="pFileName">File name include path to store the chart</param>
/// <param name="pAnlagekennlinie">Anlagekennlinie data object</param>
public void Create(string pFileName, easyPlanData.Anlagekennlinie pAnlagekennlinie)

{
    //* default values *
    int lWidth = 605;
    int lHeight = 495;
    int lBorderSpacing = 45;
    int lXLabelSpacing = 30;
    int lYLabelSpacing = 30;
    string lXLabel = "Q [l/s]";
    string lYLabel = "H [mWS]";
    bool lShowScaling = false;       //* test mode: true *

    //* save Anlagekennlinie values *
    this.Anlagekennlinie = pAnlagekennlinie;

    //* create Analgekennlinie line chart *
    if (pFileName == "")
    {
        throw new System.Exception("Anlagekennlinie Chart method Create: has no Filename (parameter)");
    }

    this.Chart = new SIC.Draw.LineChart();
    this.Chart.Create(pFileName, this.XAxis, this.YAxis, this.Points, SIC.Draw.LineChartType.Curve,
                      pWidth: lWidth, pHeight: lHeight,
                      pBorderSpacing: lBorderSpacing, pXLabelSpacing: lXLabelSpacing, pYLabelSpacing: lYLabelSpacing,
                      pShowScaling: lShowScaling,
                      pPoints2: this.Points2,
                      pXLabel: lXLabel,
                      pYLabel: lYLabel);

    //* store the saved file name *
    this.FileName = this.Chart.File;
}
