The following members return ShapePictureFill objects:
Remarks
To access an object exposing the ShapePictureFill interface, use the ShapeFill.PictureFill property.
To apply a picture fill to a chart element, call the ShapeFill.SetPictureFill method. Then, use the ShapePictureFill object’s properties to adjust the picture fill settings: specify the portion of the picture used for the fill (by utilizing the ShapePictureFill.SourceRect property), tile picture as texture (by setting the ShapePictureFill.Stretch property to false) and fine-tune the tiling options (by using the ShapePictureFill.AlignType, ShapePictureFill.ScaleX, ShapePictureFill.ScaleY, ShapePictureFill.OffsetX and ShapePictureFill.OffsetY properties).
The ShapePictureFill interface inherits the specific fill options from the ShapeComplexFill interface. These options allow you to set the fill region (ShapeComplexFill.FillRect) and specify whether the fill should be rotated with the shape (ShapeComplexFill.RotateWithShape).
Example
The example below demonstrates how to create a clustered column chart and adjust its appearance. First, add the chart title and change the font color via the ShapeTextFont.Color property. Make the plot area transparent by using the ShapeOutlineFill.SetNoFill method, and then apply the gradient fill to the chart area by utilizing the ShapeOutlineFill.SetGradientFill method. To set the picture fill for all columns in a chart, call the ShapeFill.SetPictureFill method for a series object. Finally, change the color of the primary axes by utilizing the ShapeOutlineFill.SetSolidFill method and specify the axis width via the ShapeOutline.Width property.
Worksheet worksheet = workbook.Worksheets["chartTask7"];
workbook.Worksheets.ActiveWorksheet = worksheet;
// Create a chart and specify its location.
Chart chart = worksheet.Charts.Add(ChartType.ColumnClustered, worksheet["B2:C8"]);
chart.TopLeftCell = worksheet.Cells["F2"];
chart.BottomRightCell = worksheet.Cells["N17"];
// Add and format the chart title.
chart.Title.SetValue("Countries with the largest forest area");
chart.Title.Font.Color = Color.FromArgb(0x34, 0x5E, 0x25);
// Set no fill for the plot area.
chart.PlotArea.Fill.SetNoFill();
// Apply the gradient fill to the chart area.
chart.Fill.SetGradientFill(ShapeGradientType.Linear, Color.FromArgb(0xFD, 0xEA, 0xDA), Color.FromArgb(0x77, 0x93, 0x3C));
ShapeGradientFill gradientFill = chart.Fill.GradientFill;
gradientFill.Stops.Add(0.78f, Color.FromArgb(0xB7, 0xDE, 0xE8));
gradientFill.Angle = 90;
// Set the picture fill for the data series.
chart.Series[0].Fill.SetPictureFill("Pictures\\PictureFill.png");
// Customize the axis appearance.
AxisCollection axisCollection = chart.PrimaryAxes;
foreach (Axis axis in axisCollection)
{
axis.MajorTickMarks = AxisTickMarks.None;
axis.Outline.SetSolidFill(Color.FromArgb(0x34, 0x5E, 0x25));
axis.Outline.Width = 1.25;
}
// Change the scale of the value axis.
Axis valueAxis = axisCollection[1];
valueAxis.Scaling.AutoMax = false;
valueAxis.Scaling.Max = 8000000;
valueAxis.Scaling.AutoMin = false;
valueAxis.Scaling.Min = 0;
// Specify display units for the value axis.
