Rendering Options

The chart rendering options are accessible from the Chart > Rendering major tab. Following is a description of these options.

Auto Refresh Interval - specifies the amount of time (in milliseconds) at which the web part is automatically refreshed. A value of 0 indicates that the web part is not automatically refreshed.

Use the Auto Refresh feature only when needed - for example for presenting a regularly changing data source (realtime data).
The Auto Refresh feature is expensive to use in general, since each web part refresh will request a new reaggregation of the data.
If you need to provide users with the ability to manually refresh a specific web part (at a button click for example) - you can use the take a look at the NRefreshWebPart JScript function, which is described in the Custom Parameters with Nevron JavaScript API topic.

Width - the width of the chart in pixels.

Height - the height of the chart in pixels.

Image Acquisition Mode - specifies the way in which the client browser acquires the web part image. Possible values are:

Image Format - specifies the format of the image generated by Nevron Chart for SharePoint at runtime. By default set to PNG - possible values are Bmp, Jpeg, Png and Gif.

Render Image Map - specifies whether Nevron Chart for SharePoint should render an image map. The web part can generate an image map, which contains information about tooltips, actions etc. The image map should be rendered, if the web part is designed to be interactive. You should consider setting this property to false, if the web part does not need any interactivity features. This will speed up its rendering.

Enable 3D Antialiasing - this setting is regarded when the chart is rendering in 3D. When checked you can additionally specify the number of image samples generated by the control in order to produce smooth edges for 3D objects. The default setting for 3D antialiasing samples is 4.

Enable 2D Antialiasing - turns on or off the antialiasing of 2D objects.

Text Rendering Mode - allows you to specify the text rasterization mode. The following settings are available:

Use Regional Settings - specifies whether specific regional (culture) settings must be used. When unchecked the webpart will use the server default culture settings. When checked the culture with the specified culture name is used.

Culture Name - a string, which determines the culture with which the chart is rendered, when Use Regional Settings is checked. The culture controls the formatting of all numbers and dates displayed by Nevron Chart for SharePoint. If left blank, the chart will use the default server culture. See the Culture Table for a list of all acceptable culture names.
