In XML, if you specify such values, it will give a error while converting to number. So, FusionCharts accepts the input decimal and thousand separator from user, so that it can covert it accordingly into the required format. This attribute lets you input the decimal separator. For more details, please see Advanced Number Formatting section.
inThousandSeparator | String | Character | In some countries, commas are used as decimal separators and dots as thousand separators. In XML, if you specify such values, it will give a error while converting to number. So, FusionCharts accepts the input decimal and thousand separator from user, so that it can covert it accordingly into the required format. This attribute lets you input the thousand separator. For more details, please see Advanced Number Formatting section.

Font Properties
Using the attributes below, you can define the generic font properties for all the text on the chart. These attributes allow you a high level control over font properties. If you intend to specify font properties for individual chart elements (like Caption, sub-caption etc.), you'll need to use the STYLES feature of FusionCharts v3. Using STYLES, you can also specify advanced font properties like Bold, Italics, HTML Mode etc.

Attribute Name | Type | Range | Description
baseFont | String | Font Name | This attribute lets you set the font face (family) of all the text (data labels, values etc.) on chart. If you specify outCnvBaseFont attribute also, then this attribute controls only the font face of text within the chart canvas bounds.
baseFontSize | Number | 0-72 | This attribute sets the base font size of the chart i.e., all the values and the names in the chart which lie on the canvas will be displayed using the font size provided here.
baseFontColor | Color |  | This attribute sets the base font color of the chart i.e., all the values and the names in the chart which lie on the canvas will be displayed using the font color provided here.

Tool-tip
These attributes let you control the tool tip. You can set the background color, border color, separator character and few other details.

Attribute Name | Type | Range | Description

toolTipBgColor | Color |  | Background Color for tool tip.
toolTipBorderColor | Color |  | Border Color for tool tip.
toolTipSepChar | String |  | The character specified as the value of this attribute separates the name and value displayed in tool tip.

Chart Padding & Margins
The following attributes help you control chart margins and paddings. FusionCharts v3 allows you manually customize the padding of various elements on the chart to allow advanced manipulation and control over chart visualization. Padding in FusionCharts is always defined in pixels, unless the attribute itself suggests some other scale (like plotSpacePercent). You can also define the chart margins. Chart Margins refer to the empty space left on the top, bottom, left and right of the chart. That means, FusionCharts wouldn't plot anything in that space. It's not necessary for you to specify any padding/margin values. FusionCharts automatically assumes the best values for the same, if you do not specify the same.

Attribute Name | Type | Range | Description
captionPadding | Number | In Pixels | This attribute lets you control the space (in pixels) between the sub-caption and top of the chart canvas. If the sub-caption is not defined, it controls the space between caption and top of chart canvas. If neither caption, nor sub-caption is defined, this padding does not come into play.
chartLeftMargin | Number | In Pixels | Amount of empty space that you want to put on the left side of your chart. Nothing is rendered in this space.
chartRightMargin | Number | In Pixels | Amount of empty space that you want to put on the right side of your chart. Nothing is rendered in this space.
chartTopMargin | Number | In Pixels | Amount of empty space that you want to put on the top of your chart. Nothing is rendered in this space.
chartBottomMargin | Number | In Pixels | Amount of empty space that you want to put on the bottom of your chart. Nothing is rendered in this space.

<set> element
Each <set> element (child of <chart> or <dataset> element) represents a set of data which is to be plotted on the graph and determines a set of data which would appear on the chart. For a single series chart, a typical <set> element would look like: <set label='January' value='17400' /> For a multi-series chart, it could look like: <dataset seriesName='2006'> <set value='35445' /> <set value='35675' /> .... and so on .... </dataset> In multi-series/combination charts, you should again note that the number of <category> elements should be equal to the number of data points in each data sets, i.e., if you mention twelve categories (twelve months), the data for both years (2005 & 2006) should also contain twelve <set> elements (twelve rows of data).

Attribute Name | Type | Range | Description
borderColor | Color | Hex Code | If you want to set border color of individual pie/doughnut data items, you can specify using this attribute.
borderAlpha | Color | Hex Code | If you want to set border alpha of individual pie/doughnut data items, you can specify using this attribute.

value | Number |  | Numerical value for the data item. This value would be plotted on the chart.
color | Color | Hex Code | If you want to define your own colors for the data items on chart, use this attribute to specify color for the data item. This attribute accepts hex color codes without #.
link | String |  | You can define links for individual data items. That enables the end user to click on data items (columns, lines, bars etc.) and drill down to other pages. To define the link for data items, use the link attribute. You can define links that open in same window, new window, pop-up window or frames. Please see "Advanced Charting > Drill Down Charts" for more information. Also, you'll need to URL Encode all the special characters (like ? and &) present in the link.
toolText | String |  | By default, FusionCharts shows the data item name and value as tool tip text for that data item. But, if you want to display more information for the data item as tool tip, you can use this attribute to specify the same.
dashed | Boolean | 0/1 | Whether the border of this data item should appear as dashed? This is particularly useful when you want to highlight a data (such as forecast or trend etc.).
alpha | Number | 0-100 | This attribute determines the transparency of a data item. The range for this attribute is 0 to 100. 0 means complete transparency (the data item won’t be shown on the graph) and 100 means opaque.
