Adding Special Characters
FusionCharts offers multiple options to format numbers on the chart. You can configure number prefixes and suffixes, decimal places, and scale numbers based on a predefined scale. This article focuses on how you customize the prefix and suffix of the numbers on the chart using FusionCharts JSP wrapper.
To customize the prefix and suffix of the numbers on the chart, use the following attributes:
Specify the prefix for all the values on the chart using the
numberPrefixattribute. Note that the value of this attribute works only if you don't specifically mention the values of theyNumberPrefixandxNumberPrefixattributes.Specify the prefix for all the Y-axis values on the chart using the
yNumberPrefixattribute. If you don't mention this attribute, the chart will inherit the default value from thenumberPrefixattribute.Specify the prefix for all the X-axis values on the chart using the
xNumberPrefixattribute. If you don't mention this attribute, the chart will inherit the default value from thenumberPrefixattribute.Specify the suffix for all the values on the chart using the
numberSuffixattribute. Note that the value of this attribute works only if you don't specifically mention the values of theyNumberSuffixandxNumberSuffixattributes.Specify the suffix for all the Y-axis values on the chart using the
yNumberSuffixattribute. If you don't mention this attribute, the chart will inherit the default value from thenumberSuffixattribute.Specify the suffix for all the X-axis values on the chart using the
xNumberSuffixattribute. If you don't mention this attribute, the chart will inherit the default value from thenumberSuffixattribute.
A chart configured to customize the prefix of the numbers on the chart is shown below:
{
"chart": {
"caption": "Monthly revenue for last year",
"subCaption": "Harry's SuperMart",
"xAxisName": "Month",
"yAxisName": "Revenues (In USD)",
"numberPrefix": "$",
"theme": "fusion"
},
"data": [
{
"label": "Jan",
"value": "420000"
},
{
"label": "Feb",
"value": "810000"
},
{
"label": "Mar",
"value": "720000"
},
{
"label": "Apr",
"value": "550000"
},
{
"label": "May",
"value": "910000"
},
{
"label": "Jun",
"value": "510000"
},
{
"label": "Jul",
"value": "680000"
},
{
"label": "Aug",

{
"label": "Nov",
"value": "900000"
},
{
"label": "Dec",
"value": "730000"
}
]
}
