My problem currently is that the data shows up like it's suppose to in the excel file but the chart doesn't appear correctly. I am trying Method 1: http://www.dotnetperls.com/excel. I have already looked at this: Excel Interop Apply Chart Template
Charts: (https://i.sstatic.net/gl6E8.jpg) The top image is what I get the bottom image is what I want.
string tempPath = Path.GetTempPath();
//C:\appdata...\LicenseCheck
string folderPath = string.Format(@"{0}\LicenseCheck", tempPath);
//The csv file with the XMAX license usage stats
string secondPath = string.Format(@"{0}\{1}_Report_Stats_{2}_{3}.csv",
folderPath, productName, lastCheckedDate.Month, lastCheckedDate.Year);
var application = new Application();
var workbook = application.Workbooks.Open(secondPath);
var worksheet = workbook.Worksheets[1] as Worksheet;
object misValue = System.Reflection.Missing.Value;
// Add chart.
var charts = worksheet.ChartObjects() as ChartObjects;
var chartObject = charts.Add(60, 10, 300, 300) as ChartObject;
var chart = chartObject.Chart;
// Set chart range.
var range = worksheet.get_Range("A1", "C25");
chart.SetSourceData(range);
// Set chart properties.
chart.ChartType = XlChartType.xlColumnClustered;
chart.ChartWizard
(
Source: range
// Title: "graphTitle",
// CategoryTitle: "xAxis",
// ValueTitle: "yAxis"
);
chartObject.Chart.ApplyChartTemplate(@"C:\\LicenseUsageStatsTemplate.crtx");
// Save.
workbook.SaveAs("Stats.xls", XlFileFormat.xlWorkbookNormal);
workbook.Close(true, misValue, misValue);
application.Quit();
releaseObject(worksheet);
releaseObject(workbook);
releaseObject(application);
Found out that MS office had to be installed on the server to use Interop. So, ended up using EPPlus. It's an awesome library that uses OfficeOpenXML.
