ShapeGradientFill.Stops Property

Provides access to the gradient stop collection.

Namespace: DevExpress.Spreadsheet.Drawings

Assembly: DevExpress.Spreadsheet.v24.1.Core.dll

NuGet Package: DevExpress.Spreadsheet.Core

Declaration

GradientStopCollection Stops { get; }

Property Value

Type Description
GradientStopCollection

A GradientStopCollection object that is the collection of color stop points.

Remarks

Call the ShapeOutlineFill.SetGradientFill method to apply a gradient fill to a chart element. Use the Stops property to access the gradient stop collection, which allows you to remove the existing gradient stops or add additional stops for a more complex gradient.

Note

Currently, the SpreadsheetControl supports only a linear gradient with two color stops at the beginning and at the end of a gradient line. Therefore, other gradient types (like radial, rectangular or path) will be displayed as a linear gradient between the starting and ending colors when you load the document in the SpreadsheetControl. However, the gradient fill settings can be accessed in code, exported in supported formats and visualized in Microsoft Excel.

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.
valueAxis.DisplayUnits.UnitType = DisplayUnitType.Thousands;
valueAxis.DisplayUnits.ShowLabel = true;

// Hide the legend.
chart.Legend.Visible = false;
