Dear Support,

I was curious if you could look into something for me/clarify the support of a scenario. I have a spreadsheet that I would like to insert data into and that spreadsheet has a graph defined in it. Can I:

1. Insert the data (this is normal - so yes)
2. Modify the graph (x-axis, y-axis, size, etc.)
3. Save the document

#1 and #3 are a yes because I do it all the time. #2 is my big question mark.

Lastly, right now with my spreadsheet when I insert the data and open it, I get an error File Error: Data may have been lost. I have several examples that I can forward.

Thanks,

Richard

Dear Richard,

Thanks for your inquiry.
For #2, please try sample code below. We attached the tested excel files.
Code: Select all
           Workbook workbook = new Workbook();
            workbook.LoadFromFile(@"..\..\sample.xlsx");
 
            Chart chart = workbook.Worksheets[0].Charts[0];
           //modify chart size
            chart.Height = 500;
            chart.Width = 700;
           
          //modify y-axis minValue and maxValue
            chart.PrimaryValueAxis.MaxValue = 12000;
            chart.PrimaryValueAxis.MinValue = 0;
         
            //modify x-axis title
            chart.PrimaryCategoryAxis.Title = "Month(Jun-Sep)";

            chart.PrimaryValueAxis.HasMajorGridLines = true;
            workbook.SaveToFile("result.xlsx",ExcelVersion.Version2007);

For an error File Error, could you please provide us your template file, data and code? So that we can reproduce the error you met soon and work out a solution for you. Thank you in advance!

Amy,

Sorry I was out of town and the forums reply where going to my spam so I didn't see them.

So I tried the file you attached and it works fine so there must be something about my file. I will follow up with an e-mail on the file that I'm using and maybe you can reproduce the error.

Thanks,

Richard
