The web part exposes visual editors for the editing of fill styles, stroke styles, text styles etc. for all gauge elements. Fill styles, strokes styles, text styles etc. are generally called appearance styles, which are edited with appearance editors. The following list summarizes the appearance editors and links to the topics you can read to start working with them quickly:

Fill Style Editor

Stroke Style Editor

Shadow Style Editor

Text Style Editor

Frame Style Editor

Every appearance style editor has an Automatic check box located in its upper left corner. If you check it and press the Ok button of the editor, you instruct Nevron Gauge for SharePoint to determine this appearance style automatically.

All appearance styles are displayed and edited by buttons, which have a preview box in their left side. The preview box displays a checker board with a blue "a" inside, whenever the particular appearance style is automatically determined. By default all appearance styles are automatically determined.

When an appearance style is in automatic mode its value is determined by the currently applied style sheet. The current style sheet is determined by a two stage process:

1. The component checks whether the local gauge area style sheet is enabled (the local style sheet for GaugeArea0 is located at: Gauge > Gauge Areas > Gauge Area 0 > Appearance). If so, the component will get definitions for automatic appearance styles from the local, currently selected style sheet.
2. If the local style sheet is set to automatic, the component will use the global style sheet (located at Gauge > Appearance).

Following is an overview of the style sheet settings:

Palette - allows you to choose the current palette for the style sheet.

Apply To Indicators - whether to apply the style sheet settings to indicators (pointers and ranges).

Apply To Numeric Displays - whether to apply the style sheet settings to numeric displays.

Apply To Borders - whether to apply the style sheet settings to borders.

Apply To Axes - whether to apply the style sheet settings to axis ruler, ticks and labels used in Linear and Radial Gauges.

Besides appearance styles XML formatted texts play central role in the gauge appearance customization, since they help you display titles, headers, footers etc. in a rich text format with many options. See  XML Formatted Texts for more information.
