C1.Web.C1WebChart.2

Clears the internal C1Chart or C1Chart3D of all data and settings.

Note that only the C1.Win.C1Chart data and properties are cleared by this method. C1WebChart properties are not modified.

Gets or sets the name of the control that should be shown during callback to provide visual feedback.

Gets or sets the url of an image that should be shown during callback to provide visual feedback.

Gets or sets a value indicating whether the control uses callback mechanism to load requested page to client.

Occurs when the chart is clicked.

The event handler receives an argument of type ImageClickEventArgs containing data related to this event. Note: this event causes the page to be posted back to the server.

Gets or sets the Image format to be used for the client side image.

Note that while this property accepts a .Net ImageFormat value, the only image formats available to the C1WebChart programmer are gif, jpeg, and png.

Gets or sets the image quality created when the ImageFormat is set to jpeg.

This property accepts an integer from 0 to 100 which specifies the quality of the jpeg image file.

Specifies the absolute expiration time when the image expires from the session, cache, or file object.

Gets or sets the interval between the time the image was last accessed and the time when the image expires from the session, cache, or file object.

If this value is the equivalent of 5 minutes, the image expires and is removed from the transfer object 5 minutes after it was last accessed.

Gets or sets the control background color.

Gets or sets the control foreground color.

Fires when chart is drawn.

The event handler receives an argument of type PaintEventArgs containing data related to this event.

Gets or sets the location of background image.

Specifies an Href for the MapArea.

Each MapArea in the resulting ImageMap can link to another URL. If this property is set to a valid address, clicking on the MapArea will link users to the specified page. Note: the Href is automatically HTML encoded as appropriate (unless it is a JavaScript url).

Specifies a tooltip for the MapArea.

Each MapArea can have a tooltip string specified. The tooltip appears when the end-user scrolls over the appointed MapArea. The string is automatically HTML encoded as appropriate and appears as the value of the <AREA> tag Title attribute. There are special entries for Tooltip entries that will be translated by the chart.

Specifies a set of attributes to be added to the <AREA> tag.

Each MapArea can have additional attributes set as appropriate for <AREA> tags. For more information on <AREA> tags see the Microsoft documentation. Setting this property causes the specified string to appear as a set of attributes for the MapArea. Note that the attribute value is added to the <AREA> tag as a literal string, so any encoding necessary must be performed to the property value.

Tests whether the map area is custom.

Custom maps are not associated with chart elements and data.

Gets or sets the map area name.

Gets or sets the array of coordinates of map area.

Tests whether the map area is empty.

Use the members of this enumeration to set the value of the property in the C1WebChart class.

C1WebChart will generate image files that can be referenced directly by an <IMG> tag. The <IMG> tag will be generated and will reference the file specified by the ImageUri property. If the ImageUri property is not specified, then a name for the temporary file will be generated and the URL will reference the temporary file.

C1WebChart supports the IHTTPHandler interface and will generate an appropriately placed <IMG> tag within the page that references its internal HTTPHandler to stream the image to the client.

C1WebChart will perform a binary write to its host page response stream directly, without transferring data to another page. However, the binary image data will be the only data returned.

C1WebChart will utilize a secondary asp(x) page to stream the image data back to an imbedded <IMG> tag on the primary page. If this option is selected, the chart will generate an appropriately placed <IMG> tag within the page that hosts the chart. The positioning of the <IMG> tag will be in the same location as shown on the Visual Studio design page, and <IMG> tag src attribute will reference the specified asp(x) page. The path to the page will be that specified by the ImageUri property.

C1WebChart does nothing to render itself at runtime. All operations required for generating and placing the chart image within the page are the responsibility of the programmer.

Gets the MapAreaCollection object used to generate client side image maps.

The ImageAreas property exposes a collection of objects. This collection defines the properties of the generated image map to be used for end-user interaction. Each object in turn specifies the behaviors of the image map.

Gets the control ChartArea object.

The ChartArea is that region of the chart that contains axes and charted data. Its Style inherits directly from the parent C1WebChart.ChartStyle.

Indicates the method by which the HTML image tag source URL is rendered.

For more information, see the ImageRenderMethod Property topic.

Indicates the method by which image data is transferred to the source page.

When a secondary URL is used to stream image data back to an <IMG> tag on the primary page, it is necessary to transfer the chart data through either a session object, cache object, or a file.

Gets or sets the level of uniqueness of the ID transfer object.

When chart data is transferred from one page to another, IDs are created for the Session or Cache variables or for a filename in order to render a chart image. This property determines whether a unique ID is created each time the chart image is accessed (i.e. when the chart image is accessed by a single user), or if the same ID is to be used for the duration of the application life (i.e. when the identical chart image is accessed by multiple users or accessed repeatedly by a single user). Note: The ImageIdGeneration property has no effect with the ImageRenderMethodEnum.File or ImageRenderMethodEnum.BinaryWrite.

Specifies a path for various render methods.

This property specifies a pathname. It has different applications for different properties and settings. For more information, see ImageRenderMethod Property. Also refer to File-based Rendering Tutorials, HTTPHandler-based Rendering Tutorials, and ASP Page-based Rendering Tutorials.

Gets or sets a value indicating whether to use anti-aliasing while rendering chart text (only).

Gets or sets a value indicating whether to use anti-aliasing while rendering chart graphics (only).

Gets or sets a value indicating whether to render the chart with grayscale instead of color. The use of Grayscale is intended as a preview for output to a black and white device. It does not affect style brush or pen colors internally, only the rendering of the chart to the output devices and images. Using grayscale implies the use of double buffered output.

Gets or sets a value specifying theme based automatic color generation. The default value is ColorGeneration.Custom which specifies the standard color generation method used by C1Chart. The remaining options mimic the color themes of Microsoft Office.

Gets or sets the alternate text displayed in the control when the image is unavailable. Browsers that support the ToolTips feature display this text as a ToolTip.

Gets or sets the location to a detailed description for the image.

Gets or sets a value indicating whether the control generates an alternate text attribute for an empty string value.

Gets or sets the alignment of the control in relation to other elements on the Web page.

Occurs when a chart General callback is made.

The event handler receives an argument of type C1WebChartCallbackEventArgs containing string data related to this event. Use the client side General callback to pass your own data in string form to the server. Based on the content of your string data, you can change any and all aspects of the chart and obtain a new image and image map as a result of the callback. The General callback is typically used when a callback from an input object on the web page is desired - e.g. a button, onclick.

Gets the control’s AssemblyFileVersion as a string. The AssemblyFileVersion is also viewable from the properties dialog of the control assembly dll.

The AssemblyFileVersion is different from the AssemblyVersion. The AssemblyFileVersion is viewable from the properties dialog of the control assembly dll. The AssemblyVersion is also listed in the properties dialog, but only in the “other version information” section. When viewing the Global Assembly Cache (GAC) in Windows Explorer, the AssemblyVersion is shown as a standard column. The AssemblyFileVersion will always change with each separate release of the Chart control, including internal changes. The AssemblyVersion will only change when the object model has been changed.
