Encapsulates the formatting options for line elements.

[ API set: ExcelApi 1.1 ]

Extends

Properties

color

HTML color code representing the color of lines in the chart.

[ API set: ExcelApi 1.1 ]

context

The request context associated with the object. This connects the add-in's process to the Office host application's process.

lineStyle

Represents the line style. See Excel.ChartLineStyle for details.

[ API set: ExcelApi 1.7 ]

weight

Represents weight of the line, in points.

[ API set: ExcelApi 1.7 ]

Methods

clear()

Clear the line format of a chart element.

[ API set: ExcelApi 1.1 ]

load(option)

Queues up a command to load the specified properties of the object. You must call "context.sync()" before reading the properties.

load(propertyNames)

Queues up a command to load the specified properties of the object. You must call context.sync() before reading the properties.

load(propertyNamesAndPaths)

Queues up a command to load the specified properties of the object. You must call context.sync() before reading the properties.

set(properties, options)

Sets multiple properties of an object at the same time. You can pass either a plain object with the appropriate properties, or another API object of the same type.

set(properties)

Sets multiple properties on the object at the same time, based on an existing loaded object.

toJSON()

Overrides the JavaScript toJSON() method in order to provide more useful output when an API object is passed to JSON.stringify(). (JSON.stringify, in turn, calls the toJSON method of the object that is passed to it.) Whereas the original Excel.ChartLineFormat object is an API object, the toJSON method returns a plain JavaScript object (typed as Excel.Interfaces.ChartLineFormatData) that contains shallow copies of any loaded child properties from the original object.

Method Details

clear()

Clear the line format of a chart element.

[ API set: ExcelApi 1.1 ]

clear(): void;

Returns

void

Examples

// Set to show legend of Chart1 and make it on top of the chart.
Excel.run(function (ctx) { 
    var gridlines = ctx.workbook.worksheets.getItem("Sheet1").charts.getItem("Chart1").axes.valueAxis.majorGridlines;
    gridlines.format.line.clear();
    return ctx.sync().then(function() {
            console.log("Chart Major Gridlines Format Cleared");
    });
}).catch(function(error) {
    console.log("Error: " + error);
    if (error instanceof OfficeExtension.Error) {
        console.log("Debug info: " + JSON.stringify(error.debugInfo));
    }
});

load(option)

Queues up a command to load the specified properties of the object. You must call "context.sync()" before reading the properties.

load(option?: Excel.Interfaces.ChartLineFormatLoadOptions): Excel.ChartLineFormat;

Parameters

Returns

Remarks

In addition to this signature, this method has the following signatures:

load(option?: string | string[]): Excel.ChartLineFormat - Where option is a comma-delimited string or an array of strings that specify the properties to load.

load(option?: { select?: string; expand?: string; }): Excel.ChartLineFormat - Where option.select is a comma-delimited string that specifies the properties to load, and options.expand is a comma-delimited string that specifies the navigation properties to load.

load(option?: { select?: string; expand?: string; top?: number; skip?: number }): Excel.ChartLineFormat - Only available on collection types. It is similar to the preceding signature. Option.top specifies the maximum number of collection items that can be included in the result. Option.skip specifies the number of items that are to be skipped and not included in the result. If option.top is specified, the result set will start after skipping the specified number of items.

load(propertyNames)

Queues up a command to load the specified properties of the object. You must call context.sync() before reading the properties.

load(propertyNames?: string | string[]): Excel.ChartLineFormat;

Parameters

propertyNames
string | string[]

A comma-delimited string or an array of strings that specify the properties to load.

Returns

Examples

// Set chart major gridlines on value axis to be red.
Excel.run(function (ctx) {
    var gridlines = ctx.workbook.worksheets.getItem("Sheet1").charts.getItem("Chart1").axes.valueAxis.majorGridlines;
    gridlines.format.line.color = "#FF0000";
    return ctx.sync().then(function () {
        console.log("Chart Gridlines Color Updated");
    });
}).catch(function (error) {
    console.log("Error: " + error);
    if (error instanceof OfficeExtension.Error) {
        console.log("Debug info: " + JSON.stringify(error.debugInfo));
    }
});

load(propertyNamesAndPaths)

Queues up a command to load the specified properties of the object. You must call context.sync() before reading the properties.

load(propertyNamesAndPaths?: { select?: string; expand?: string; }): Excel.ChartLineFormat;

Parameters

propertyNamesAndPaths
{ select?: string; expand?: string; }

Where propertyNamesAndPaths.select is a comma-delimited string that specifies the properties to load, and propertyNamesAndPaths.expand is a comma-delimited string that specifies the navigation properties to load.

Returns

set(properties, options)

Sets multiple properties of an object at the same time. You can pass either a plain object with the appropriate properties, or another API object of the same type.

set(properties: Interfaces.ChartLineFormatUpdateData, options?: OfficeExtension.UpdateOptions): void;

Parameters

properties
Interfaces.ChartLineFormatUpdateData

A JavaScript object with properties that are structured isomorphically to the properties of the object on which the method is called.

options
OfficeExtension.UpdateOptions

Provides an option to suppress errors if the properties object tries to set any read-only properties.

Returns

void

Remarks

This method has the following additional signature:

set(properties: Excel.ChartLineFormat): void

set(properties)

Sets multiple properties on the object at the same time, based on an existing loaded object.

set(properties: Excel.ChartLineFormat): void;

Parameters

Returns

void
