To add accessibility text for charts, adding following code snippet in the JS listener for the workspace that contain the chart widgets:
CWEH.registerHandler('<Chart Widget Id>', CFEC.WIDGET_RENDERED, function()
{
FusionCharts.Accessibility.setAlternateTexts(
{
'<Chart ID>':
{
'chart': 'This is a {chartType} chart with static colors',
'plot': 'On date {label}, the revenue is {value}.'
}
});
}
//here, Chart ID = <VIEW_ID>_<WIDGET_ID>_CHART
//Chart Widget Id / Widget ID = Chart app ID
The default accessibility texts for the single-series and multi-series charts, and gauges is shown in the following code snippet:
//Single-series charts
{
'chart': 'This is a {chartType} chart showing {xAxisName} and {yAxisName}. ',
'plot': '{label} value is {value}. Plot {plotIndex} of {totalPlots}.'
}
//Multi-series charts
{
'chart': 'This is a {chartType} chart. {xAxisName} is plotted on x axis and {yAxisName} is plotted on y axis.',
'plot': '{seriesName} for the {label} is {value}. Plot {plotIndex} of {totalPlots}. Series {seriesIndex} of {totalSeries}.'
}
//Gauges
{
'chart': 'This is a {chartType} chart showing {xAxisName} and {yAxisName}',
'plot': '{label} value is {value}. Plot {plotIndex} of {totalPlots}.'
}
