#### Formatting the gauge

A gauge chart can be formatted to take some special appearances. The formatting options vary with the subtypes: Gauge Dial 2-D, Gauge Bar 2-D, and Gauge Bubble 2-D.

To format a dial gauge chart:

1. Right-click any pointer in a dial of the dial gauge chart, and then select Format Dial Gauge to display the Format Dial Gauge dialog.
2. In the General tab, specify the general options for the dials in the chart.

   In the Circular box, set the start angle and stop angle of the dials, the dial curve style, the width of the dials, and the relative size of a dial. In the Pointer box, set the pointer style and arrow style. In the Color Range box, specify whether or not to fill the dial with colors, and if to fill, set the minimum and maximum values, color, and name for the three predefined ranges in each dial.

3. In the Fill and Border tabs, set the fill and border modes for the pointers (for details, see Formatting the platform). Click the Pattern List button in the Fill tab to specify the patterns that will apply to the pointers according to your requirements.
4. In the Data Label tab, set the font formats and effects of the data labels. The data labels will be showed when you move the mouse pointer over the dial pointers in view mode or in JReport Web.
5. When done, click OK to apply the settings.

To format a bar gauge chart:

1. Right-click any data marks in a scale of the bar gauge chart, and then select Format Bar Gauge to display the Format Bar Gauge dialog.

   In the Option box, decide the layout of the scales in the gauge chart. In the Range Border box, set the color, style, transparency, and thickness of the scale borders. In the Color Range box, specify the minimum and maximum values, color, and name for the three predefined ranges in each scale.

3. In the Fill and Border tabs, set the fill and border modes for the data marks (for details, see Formatting the platform). Click the Pattern List button in the Fill tab to specify the patterns that will apply to the data marks according to your requirements.

To format a bubble gauge chart:

1. Right-click any bubble in the bubble gauge chart, and then select Format Bubble Gauge to display the Format Bubble Gauge dialog.
2. In the General tab, set the general options for the bubbles in the chart.

   In the Option box, set the left margin, top margin, relative radius of the bubbles, and whether or not to draw horizontal/vertical grids. In the Value box, set the minimum and maximum values. In the Color Range box, specify the minimum and maximum values, color, and name for the three predefined color ranges. If the value represented by a bubble is in a range, its color will be the one of that range.

3. In the Border tab, set the border mode for the bubbles (for details, see Formatting the platform).
4. In the Data Label tab, set the font formats and effects of the data labels. The data labels will be showed when you move the mouse pointer over the bubbles in view mode or in JReport Web.
