Configuring Standard Charts
FusionCharts Suite XT allows you to customize the appearance of standard charts.
In this section, you will be shown how you can:
-
Plot trend elements on a standard chart
-
Plot vertical line elements
-
Change the chart type dynamically
Plotting Trend Elements on a Standard Chart
The trend elements that can be plotted on a chart include trend-lines and trend-zones.
Trend-lines are customizable reference horizontal or vertical lines which aid in interpretation of data. They can be used to set context or define limits and targets. For example, while plotting quarterly sales of a company, you might want to use a trend-line to depict the target sales. Trend-zones are similar to trend-lines except that they mark out an entire zone rather than just a line.
A quarterly sales summary chart rendered with a trend-line to show the target value looks like this:
{
"chart": {
"caption": "Quarterly Sales Summary",
"subcaption": "Last year",
"xaxisname": "Quarter",
"yaxisname": "Amount (In USD)",
"numberprefix": "$",
"theme": "fint"
},
"data": [
{
"label": "Q1",
"value": "195000"
},
{
"label": "Q2",
"value": "155000"
},
{
"label": "Q3",
"value": "178000"
},
{
"label": "Q4",
"value": "192000"
}
],
"trendlines": [
{
"line": [
{
"startvalue": "175000",
"color": "#1aaf5d",

Plotting Vertical Line Elements
Vertical (or horizontal in case of bar charts) separator lines are elements that can differentiate between data blocks in a chart. They can be placed between any two data points, or can be aligned to specific data points.
A line chart rendered with a vertical line looks like this:
{

"caption": "Visitors to website",

Changing Chart Type
FusionCharts Suite XT allows you to change the chart type dynamically through its advanced API. You can change chart type by calling the chartType() method on any FusionCharts’ instance and provide the chart name as an argument.
An example of a chart, where you can dynamically change the chart type, looks like this:
{
"chart": {
"caption": "Monthly revenue",
"subCaption": "Last year",
"xAxisName": "Month",
"yAxisName": "Revenue (In USD)",
"numberPrefix": "$",
"theme": "fint"
},
"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",
"value": "620000"
},
{
"label": "Sep",
"value": "610000"
},
{
"label": "Oct",
"value": "490000"

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