<!-- Create an instance of the class that exports Excel files -->
<cfobject type="java" class="EasyXLS.ExcelDocument" name="workbook" action="CREATE">

<!-- Create a worksheet -->
<cfset ret = workbook.easy_addWorksheet("SourceData")>

<!-- Get the table of data for the worksheet -->
<cfset xlsTab1 = workbook.easy_getSheet("SourceData")>
<cfset xlsTable1 = xlsTab1.easy_getExcelTable()>

<!-- Add data in cells for report header -->
<cfset xlsTable1.easy_getCell(0, 0).setValue("Show Date")>
<cfset xlsTable1.easy_getCell(0, 1).setValue("Available Places")>
<cfset xlsTable1.easy_getCell(0, 2).setValue("Available Tickets")>
<cfset xlsTable1.easy_getCell(0, 3).setValue("Sold Tickets")>

<!-- Add data in cells for chart report values -->
<cfset xlsTable1.easy_getCell(1, 0).setValue("03/13/2005 00:00:00")>
<cfset xlsTable1.easy_getCell(1, 0).setFormat(Format.FORMAT_DATE)>
<cfset xlsTable1.easy_getCell(2, 0).setValue("03/14/2005 00:00:00")>
<cfset xlsTable1.easy_getCell(2, 0).setFormat(Format.FORMAT_DATE)>
<cfset xlsTable1.easy_getCell(3, 0).setValue("03/15/2005 00:00:00")>
<cfset xlsTable1.easy_getCell(3, 0).setFormat(Format.FORMAT_DATE)>
<cfset xlsTable1.easy_getCell(4, 0).setValue("03/16/2005 00:00:00")>
<cfset xlsTable1.easy_getCell(4, 0).setFormat(Format.FORMAT_DATE)>

<cfset xlsTable1.easy_getCell(1, 1).setValue("10000")>
<cfset xlsTable1.easy_getCell(2, 1).setValue("5000")>
<cfset xlsTable1.easy_getCell(3, 1).setValue("8500")>
<cfset xlsTable1.easy_getCell(4, 1).setValue("1000")>

<cfset xlsTable1.easy_getCell(1, 2).setValue("8000")>
<cfset xlsTable1.easy_getCell(2, 2).setValue("4000")>
<cfset xlsTable1.easy_getCell(3, 2).setValue("6000")>
<cfset xlsTable1.easy_getCell(4, 2).setValue("1000")>

<cfset xlsTable1.easy_getCell(1, 3).setValue("920")>
<cfset xlsTable1.easy_getCell(2, 3).setValue("1005")>
<cfset xlsTable1.easy_getCell(3, 3).setValue("342")>
<cfset xlsTable1.easy_getCell(4, 3).setValue("967")>

<!-- Set column widths -->
<cfset xlsTable1.easy_getColumnAt(0).setWidth(100)>
<cfset xlsTable1.easy_getColumnAt(1).setWidth(100)>
<cfset xlsTable1.easy_getColumnAt(2).setWidth(100)>
<cfset xlsTable1.easy_getColumnAt(3).setWidth(100)>

<!-- Add a chart sheet -->
<cfset workbook.easy_addChart("Chart", "=SourceData!$A$1:$D$5", Chart.SERIES_IN_COLUMNS)>

<!-- Export Excel file -->
Writing file C:\Samples\Tutorial21 - chart sheet in Excel.xlsx<br>
<cfset ret = workbook.easy_WriteXLSXFile("C:\Samples\Tutorial21 - chart sheet in Excel.xlsx")>

<!-- Confirm export of Excel file -->
<cfset sError = workbook.easy_getError()>
<cfif (sError is "")>
    <cfoutput>
        File successfully created.
    </cfoutput>
<cfelse>
    <cfoutput>
        Error encountered: #sError#
    </cfoutput>
</cfif>

<!-- Dispose memory -->
<cfset workbook.Dispose()>
