// Load source excel file containing excel 2016 charts
Workbook wb = new Workbook(dataDir + "excel2016Charts.xlsx");

// Access the first worksheet which contains the charts
Worksheet ws = wb.getWorksheets().get(0);

cTypes.put(ChartType.TREEMAP, "Treemap");
cTypes.put(ChartType.HISTOGRAM, "Histogram");

// Access all charts one by one and read their types
for (int i = 0; i < ws.getCharts().getCount(); i++) {
	// Access the chart
	Chart ch = ws.getCharts().get(i);

	// Print chart type
	String strChartType = cTypes.get(ch.getType());
	System.out.println(strChartType);

	// Change the title of the charts as per their types
