2) to set Legend overlapping chart (in excell : Format Legend - Option - unchecked legend without overlapping the chart)
3) set Char area don’t move or size with cell (in excell : Format Chart area - Property- check don’t move or size with cell)

Hi Guillaume,

Thanks for your posting and using Aspose.Cells.

For 1), please use Chart.ChartObject.HeightScale property.

For 2), it is not currently available, we have logged a New Feature request in our database to support this legend option.

This issue has been logged as

  • CELLSNET-42923 - Checking or unchecking the legend option "Show the legend without overlapping the option"

For 3), please use Chart.ChartObject.Placement property.

Here is a sample code for your reference. I have attached the source Excel file used in this code and output Excel file generated by it for you to look over.

C#

Workbook workbook = new Workbook(“source.xlsx”);


Worksheet worksheet = workbook.Worksheets[0];


Chart chart = worksheet.Charts[0];


//Set the chart placement to “Don’t move and size with cells”

chart.ChartObject.Placement = PlacementType.FreeFloating;


//Set the scale height to 90 percent

chart.ChartObject.HeightScale = 90;


workbook.Save(“output.xlsx”);

thank

I think there are problem with this release.the value type are not correctly handle now

for exemple:

int? _row;

_row =15;

sheet.Cells[0, 0].PutValue(_row)Cells[0, 0].PutValue(_row);

but the result is

sheet.Cells[0, 0]_worksheetData.Cells[0, 0] ={Aspose.Cells.Cell [ A1; ValueType : IsNumeric; Value : 15 ]}

sheetData.Cells[0, 0].Value=15.0 with ab double object

Hi,


I have tested your scenario/ case a bit. I could not find any issue retrieving Cell’s type. Could you provide us your sample code (runnable) to reproduce the issue on our end, we will check it soon. Also attach your template file if you have any.

Thank you.

unfortunatly it's part of a large code.

the code breack at

_row = (int?)_worksheetData.Cells[0, 0].Value;with my old dll 7.7.2.0 there is no those problems.

try to cast

Hi,

Thanks for using Aspose.Cells.

The Cell.Type is “IsNumeric” for both int and double values, so it is not safe to cast cell value to int or double directly. From 8.0.0, we changed the data model for cells and most numeric values be kept as double in memory.

For your case, if you are sure that you should get int value from the cell, please use Cell.IntValue instead of (int)Cell.Value.

I will not said I appreciate this change in 8.0.0

I will have to go to all the code to made change.

Unfortunatly I will not be able to use your fix before months.
