Shapes Lines Line Weight

Adds lines with various weights.

// Create a new workbook and some local variables.
SpreadsheetGear.IWorkbook workbook = SpreadsheetGear.Factory.GetWorkbook();
SpreadsheetGear.IWorksheet worksheet = workbook.ActiveWorksheet;
SpreadsheetGear.IWorksheetWindowInfo windowInfo = worksheet.WindowInfo;

// We will position lines relative to a given range, starting in Row 2.
SpreadsheetGear.IRange currentRow = worksheet.Cells["2:2"];

// Position line across Columns A:E
double xStart = 10;
double xEnd = windowInfo.ColumnToPoints(5) - 10;

// Loop will generate increasingly thicker lines.
for (int i = 0; i < 12; i++)
    // Calculate Weight (in Points).
    double weight = i * 2 + 1;

    // Position line relative to "currentRow" and add a slight slope to it.
    double yStart = windowInfo.RowToPoints(currentRow.Row) - 5;
    double yEnd = yStart + 10;

    // Add the line and set its weight.
    SpreadsheetGear.Shapes.IShape lineShape = worksheet.Shapes.AddLine(xStart, yStart, 
        xEnd, yEnd);
    SpreadsheetGear.Shapes.ILineFormat lineFormat = lineShape.Line;
    lineFormat.Weight = weight;

    // Provide some information in an adjacent cell to indicate line weight.
    currentRow[0, 5].Value = $"Weight: {weight}";

    // Offset down 2 rows from the current row to prep next line.
    currentRow = currentRow.Offset(2, 0);
