Hi,


I can notice the issue as pointed out in MS Excel, error is:
“Excel found unreadable content…”

I used your template file, here is the sample code:

Sample code:

Workbook wb = new Workbook(@“e:\test2\testData.xlsx”); //Template:https://forum.aspose.com/t/104760

Worksheet wrktest = wb.Worksheets["__ifnet"];

//Adding a new worksheet to the Workbook object
int sheetIndex = wb.Worksheets.Add(SheetType.Chart);

//Obtaining the reference of the newly added worksheet by passing its sheet index
Worksheet worksheet = wb.Worksheets[sheetIndex];

int chartIndex = worksheet.Charts.Add(Aspose.Cells.Charts.ChartType.Line, 1, 1, 25, 30);

//Accessing the instance of the newly added chart
Aspose.Cells.Charts.Chart chart = worksheet.Charts[chartIndex];
Cells cell = wrktest.Cells;
//Adding NSeries (chart data source) to the chart ranging from “A1” cell to “B4”
chart.NSeries.Add("__ifnet!B2:E10", true);

chart.NSeries.CategoryData = “__ifnet!A2:A10”;
chart.NSeries.SecondCatergoryData = “__ifnet!A2:A10”;

int i;
for (i = 0; i < 3; i++)
{
string index = ((char)(66 + i)).ToString() + “1”;
chart.NSeries[i].Name = cell[index].Value.ToString();
chart.NSeries[i].Type = Aspose.Cells.Charts.ChartType.Line;
chart.NSeries[i].Line.Weight = WeightType.HairLine;
DataLabels datalabels = chart.NSeries[i].DataLabels;
datalabels.ShowValue = false;
}

string cellindex = ((char)(66 + i)).ToString() + “1”;
chart.NSeries[i].Name = cell[cellindex].Value.ToString();
chart.NSeries[i].Type = Aspose.Cells.Charts.ChartType.Line;
chart.NSeries[i].PlotOnSecondAxis = true;
chart.NSeries[i].Line.IsVisible = true;
chart.SecondCategoryAxis.IsVisible = true;

Console.WriteLine(“Applying Formatting …”);

//Formatting chart area
chart.PlotArea.Area.BackgroundColor = Color.White;
chart.ChartArea.Area.BackgroundColor = Color.White;
chart.PlotArea.Area.ForegroundColor = Color.White;
chart.ChartArea.Area.ForegroundColor = Color.White;
chart.Name = “Sample Sheet”;
chart.Title.Text = “Sample Chart”;
chart.SizeWithWindow = true;
chart.ValueAxis.IsAutomaticMajorUnit = true;
chart.SecondValueAxis.IsAutomaticMajorUnit = true;
chart.SecondValueAxis.IsVisible = true;
chart.ValueAxis.IsAutomaticMaxValue = true;
chart.SecondValueAxis.IsAutomaticMaxValue = true;


chart.Calculate();
wb.Save(@“e:\test2\testDataResult.xlsx”);

When I open the output file into Ms Excel 2007, it gives me error.

I have logged a separate ticket with an id: CELLSNET-41120 for this issue. We will look into it soon.

Thank you.

Wanted to confirm if that is available.

Arihant

Hi,


The issue’s status is fixed, so we have requested you to kindly try our latest version/fix v7.3.3.x and let us know your feedback.

Thank you.

Tried the same code as mentioned below with the latest version of Aspose.Cells v 7.3.3.1, but still it is taking same time while using the chart.calculate method. The same works fine in version 7.0.2.2

Hi,


I am able to notice the issue, you are right as I have tested using your code with template file using Aspose.Cells for .NET v7.3.3.2 , I can see the performance issue (it takes more time than it should to render/calculate the chart). I have reopened your issue “CELLSNET-41082”. We will look into it soon.

Thank you.

Do you have an update on when the fix will be available for issue: CELLSNET-41082

Hi,


We are working over your issue and hopefully we can provide you a fix for your issue “CELLSNET-41082” within the next 2-3 days.

Sorry for any inconvenience caused!

Hi,

Thanks for using Aspose.Cells.

Please try the new fix. As the number of series is too large, the performance is still very good. But the speed increased five times in the new fix.

Please download and try this fix: Aspose.Cells for .NET v7.3.3.4 and let us know your feedback.

The issues you have found earlier (filed as CELLSNET-41120) have been fixed in this update.

Hi,


Tried using the DLL version 7.3.3.4 and the performance still does not seems to improve…

Can you provide the fix for the same ASAP…

Hi,


Please download and try the our latest version/fix: Aspose.Cells for .NET v7.3.4.1
I have used the fix with your previous code and the performance is much better now.

Let us know your run results on how much time the process takes now using v7.3.4.1.

Thank you.

Tried with the latest version and there is no improvement. Compare running the same code with version 7.0.2.2 and you will notice considerable performance difference.

Hi,


We tested and there are certain improvements in the latest versions/fix that is for sure. It takes about 10 seconds to process Chart.calculate() on my normal configured machine.

Could you create a separate console application using v7.3.4.1, zip it and post it here. Also provide us how much time (in milliseconds or seconds) it takes to complete the process. We will check it soon.

Thank you.

Please find attached the latest code file alomg with the excel used and time taken with the new Dll. With 7.0.2.2 it only takes 5 seconds while with 7.3.4.1, it takes 26 mins.



Hi,

Thanks for your sample code, template file and screen shot.

I can notice the issue using your sample code (given below) with your new template file you provided in you previous post. It takes very long time to process it.

Sample code:

DateTime start = System.DateTime.Now;

Workbook test = new Workbook(@"e:\test2\Book1.xlsx");
Worksheet wrktest = test.Worksheets["__test"];

//Adding a new worksheet to the Workbook object
int sheetIndex = test.Worksheets.Add(SheetType.Chart);

//Obtaining the reference of the newly added worksheet by passing its sheet index
Worksheet worksheet = test.Worksheets[sheetIndex];

int chartIndex = worksheet.Charts.Add(Aspose.Cells.Charts.ChartType.Line, 1, 1, 25, 30);

//Accessing the instance of the newly added chart
Aspose.Cells.Charts.Chart chart = worksheet.Charts[chartIndex];

//Adding NSeries (chart data source) to the chart ranging from "A1" cell to "B4"
chart.NSeries.Add("__test!B2:AS4449", true);

chart.NSeries.CategoryData = "__test!A2:A4449";
chart.NSeries.SecondCatergoryData = "__test!A2:A4449";

////Setting the chart type of 2nd NSeries to display as line chart
chart.NSeries[0].Name = "Area One";

for (int i = 0; i < 43; i++)
{
chart.NSeries[i].Type = Aspose.Cells.Charts.ChartType.LineStacked;
chart.NSeries[i].Line.Weight = WeightType.HairLine;
DataLabels datalabels = chart.NSeries[i].DataLabels;
//datalabels.Text = "®Ù";
datalabels.ShowValue = false;
}

chart.NSeries[10].Name = "Area Two";
chart.NSeries[10].Type = Aspose.Cells.Charts.ChartType.Line;
chart.NSeries[10].PlotOnSecondAxis = true;
chart.NSeries[10].Line.IsVisible = true;
chart.SecondCategoryAxis.IsVisible = true;

Console.WriteLine("Applying Formatting ...");
//Formatting chart area

chart.PlotArea.Area.BackgroundColor = Color.White;
chart.ChartArea.Area.BackgroundColor = Color.White;
chart.PlotArea.Area.ForegroundColor = Color.White;
chart.ChartArea.Area.ForegroundColor = Color.White;
chart.Name = "Sample Sheet";
chart.Title.Text = "Sample Chart";
chart.SizeWithWindow = true;
chart.ValueAxis.IsAutomaticMajorUnit = true;
chart.SecondValueAxis.IsAutomaticMajorUnit = true;
chart.SecondValueAxis.IsVisible = true;
chart.ValueAxis.IsAutomaticMaxValue = true;
chart.SecondValueAxis.IsAutomaticMaxValue = true;


chart.Calculate();

////Saving the Excel file
test.Save(@"e:\test2\Test.xlsx", SaveFormat.Xlsx);

DateTime end = System.DateTime.Now;

Debug.WriteLine("start time :" + start);
Debug.WriteLine("end time :" + end);
Debug.WriteLine("time taken :" + (end - start));

I have logged a separate ticket with an id: "CELLSNET-41228" for your issue. We will look into your issue soon.

Thank you.
