Connect data point with line

Hi,

I am looking for the equivalent function in Aspose Cells.

In Excel I do this by right-clickung on the chart, Select data. Bottom right of that dialog is a button: "Hidden and empty cells". Here there is an option "Connect data point with line". Which property in Aspose.Cells is equivalent to this?

Hi,


Please try the following line of code for your requirements:
e.g
Sample code:

chart.PlotEmptyCellsType = PlotEmptyCellsType.Interpolated;

Thank you.


Hi,


I have used your provided code. It’s working when I export a single worksheet.
When I merge multiple worksheets into a single excel file then it’s not connecting data points with line.

Note: Each worksheet contains different type of charts(ColumnStacked, Column, line, bar)

secondWorkbook.Worksheets[“Sheet1”].Cells[34, 3].Value = null;

secondWorkbook.Worksheets[“Sheet1”].Cells[34, 4].Value = 50.00;

secondWorkbook.Worksheets[“Sheet1”].Charts[“Chart 1”].PlotEmptyCellsType = PlotEmptyCellsType.Interpolated;


//Marge first and second workbook

firstWorkbook.Combine(secondWorkbook);


//Save the excel file

firstWorkbook.Save(@“MyFile.xls”);

Hi,


Thanks for the sample project and template files.

I have evaluated your scenario/ case a bit. As a workaround, please move the lines of code (see the lines in bold) to a place after you call the merge operation and before saving the final workbook, it would work fine. Please see the updated/modified part of your code segment for your reference:
e.g
Sample code:

secondWorkbook.Worksheets[“Sheet1”].Cells[34, 1].Value = 84.00;
secondWorkbook.Worksheets[“Sheet1”].Cells[34, 2].Value = 70.00;
secondWorkbook.Worksheets[“Sheet1”].Cells[34, 3].Value = null;
secondWorkbook.Worksheets[“Sheet1”].Cells[34, 4].Value = 50.00;
//Marge first and second workbook
firstWorkbook.Combine(secondWorkbook);

firstWorkbook.Worksheets[1].Charts[“Chart 1”].PlotEmptyCellsType = PlotEmptyCellsType.Interpolated;
firstWorkbook.Worksheets[1].Charts[“Chart 1”].PlotVisibleCells = true;


//Save the excel file
firstWorkbook.Save(@“d:\MyFile.xls”);


And, we will figure out the issue soon.

Thank you.
