These attributes let you control a variety of functional elements on the chart. For example, you can opt to show/hide data labels, data values, y-axis values. You can also set chart limits and extended properties.

Attribute Name	Type	Description
editMode	Boolean (0/1)	Whether to render the gauge in edit mode? In edit mode, user can drag and rotate the dial to new values.
animation	Boolean (0/1)	This attribute lets you set the configuration whether the chart should appear in an animated fashion. If you do not want to animate any part of the chart, set this as 0.
defaultAnimation	Boolean (0/1)	By default, each chart animates some of its elements. If you wish to switch off the default animation patterns, you can set this attribute to 0. It can be particularly useful when you want to define your own animation patterns using the Styles feature.
clickURL	URL in FusionCharts format	The entire chart can now act as a hotspot. Use this URL to define the hotspot link for the chart. The link can be specified in FusionCharts Link Format.
palette	Number (1-5)	Each chart has 5 pre-defined color palettes which you can choose from. Each palette renders the chart in a different color theme. Valid values are 1-5.
paletteThemeColor	Color Code	If you want your own palette derived from a particular hex color, you can specify the same here. All other colors on the chart will be automatically derived from that palette.
annRenderDelay	Number (seconds)	If you've defined any annotation groups over chart, using this attribute you can set the duration after which they'll render on the chart. The timer starts from the time the chart has initialized.
autoScale	Boolean (0/1)	If you've defined the chart parameters (like gauge origin, co-ordinates etc.) using a different chart size and now want to scale the chart to a different size, you need to specify the original width and height and then set this attribute to 1.
manageResize Since v 3.2	Boolean (0/1)	Setting this attribute to 1, you can allow the chart to automatically resize itself when the parent container of the chart is resized. This setting is not applicable when autoScale is set to 0.
origW	Number (Pixels)	If you've opted to dynamically resize the chart, you can convey the original width of chart using this attribute. It refers to the width based on which you had defined the various co-ordinates/radius of the gauge. For example, if you had designed an angular gauge with 300 px width and in that you had set the gauge radius to be 100, then you can use the dynamic resizing feature and specify origW='300'. It will automatically check the current width and scale the radius etc. appropriately. Please note that both the original width and height of the chart need to be set. To know more on how this attribute works, please read Dynamic Resizing page.
origH	Number (Pixels)	If you've opted to dynamically resize the chart, you can convey the original height of chart using this attribute. It refers to the height based on which you had defined the various co-ordinates/radius of the gauge. For example, if you had designed an angular gauge with 300 px height and in that you had set the gauge radius to be 100, then you can use the dynamic resizing feature and specify origH='300'. It will automatically check the current height and scale the radius etc. appropriately. Please note that both the original width and height of the chart need to be set. To know more on how this attribute works, please read Dynamic Resizing page.
showValue	Boolean (0/1)	Whether to show each dial's value?
valueBelowPivot	Boolean (0/1)	Whether to show dial value below the pivot or above it?
showShadow	Boolean (0/1)	Whether to show shadow for the chart?
showPrintMenuItem	Boolean (0/1)	Whether to show "Print Chart" item in the context menu of the chart? Even if you opt to hide the item in context menu, you can still opt to invoke print() JavaScript method of the chart to print the same.
showAboutMenuItem	Boolean (0/1)	Setting this to 1 displays a custom context menu in the chart, which can be customized to show your text and can be linked to your URL. For e.g., you can set the context menu of the chart to include "About your company name" and then link to your company home page. By default, the chart shows "About FusionCharts" when right clicked.
aboutMenuItemLabel	String	The menu item label for the custom context menu item.
aboutMenuItemLink	String	Link for the custom context menu item. You can specify the link in FusionCharts link format to be able to open the same in new window, pop-ups, frames or as JavaScript links.
refreshInstantly Since v 3.2	Boolean (0/1)	By default, the real-time charts wait for a few seconds after rendering for the first time and before updating itself with new data. To allow the chart to start updating itself as soon as it is rendered, set this attribute to 1.
useEllipsesWhenOverflow Since v 3.2	Boolean (0/1)	When enabled in auto mode, long data labels are truncated by adding ellipses to prevent them from overflowing the chart background. The default value is 1.

endValue	Number	The ending value for the trend-point. Say, if you want to plot a trend-arc from value 102 to 109, the endValue will be 109.
displayValue	String	Display label for the trend-point/trend-arc. If you do not specify a value, the chart displays the numeric value.
valueInside	Boolean (0/1)	Whether to display the trend-point value inside the gauge?
color	Color Code	Color of the trend point. The color of the text can be configured using Styles.
thickness	Number (Pixels)	If you've opted to show the trend as a point, this attribute lets you define the thickness of trend line.
showBorder	Boolean (0/1)	If you're drawing a trend-arc, you can set its border on using this attribute.
borderColor	Color Code	Lets you define the border color for trend-arc.
radius	Number (Pixels)	Radius for trend point/outer side of trend-arc.
innerRadius	Number (Pixels)	In case of trend-arc, radius for inner side of arc.
dashed	Boolean (0/1)	If you're showing the trend point as line, this attribute lets you control whether the line will be plotted as dashed?
dashLen	Number (pixels)	Length of each dash, if trend-point is plotted as dashed line.
dashGap	Number (pixels)	Length of each dash gap, if trend-point is plotted as dashed line.
useMarker	Boolean (0/1)	You can opt to show a triangular marker for each trend-point by setting this attribute to 1.
markerColor	Color Code	Fill color of marker.
markerBorderColor	Color Code	Border color of marker.
markerRadius	Number (pixels)	Radius of the marker.
