Arrowhead do not appear in Linux environment

Hi. I’ve noticed there is a problem when trying to convert excel chart that contains arrow to html. In windows environment everything works fine but the problem occurs in linux environment. Arrowhead is missing. I’m using linux debian. I’m sending you code written in .net core together with simple .xlsx example that can be found in examples folder. Also, in " bin\Debug\netcoreapp3.1\Outputs" folder when you run project you will get html output that is rendered using aspose.cells library. I’ve used latest version of aspose.cells 21.7.0. I’m also attaching outputs both rendered in windows and linux.

Let us know if you still find any issue. Moreover, please make sure the following libraries are installed in your linux.

cd /usr/lib && ln -s libgdiplus.so gdiplus.dll

apt-get install -y --no-install-recommends libc6-dev

Hello @Amjad_Sahi,

did you try it with demo code in .NET core that I attached here? I’m using .NET Core in Linux so aspose cells for java does not help.


Sorry I meant Aspose.Cells for .NET. I have fixed my previous post and re-attached the latest fix of Aspose.Cells for .NET Standard, so you may try it.

Thanks. I’ve tried with .netstandard version 21.7.6 you provided and also checked that I have all libraries installed. And they were already installed. I’ve got the same issue. So, you are not missing this arrow “pointer” in linux environment that I’ve marked with green square in image attached to this post?Chart.png (45.3 KB)

We have tried your sample code and here is the output of this program that shows the arrowhead in the output HTML file.

For further investigation please share your complete environment details for our reference. We will try to reproduce the issue by establishing a similar environment.

Sure. Operating system that we use is debian gnu linux 10 (buster) 64 bit. Maybe the best way to establish similar environment is to use WSL2 on windows machine and debian linux distribution. Do you need some additional information?

Thank you for sharing more information. This issue is reproduced and logged in our database for further investigation. You will be notified here once any update is ready for sharing.
