Added Line Chart Interpolation sample

[andreassundstrom]

Issue #122
Original sample
Original sourcecode

I want to contribute to the samples. I've added a sample for the interpolation-modes in ChartJS. I'm fairly new to the github-community (not C# or dotnet-core though) so I apologize if I should have made anything different in submitting this PR. Please let me know if you want me to improve anything in the code.

I made a copy of the Pages/Charts/Line/Basic.razor-file and modified it. The original sample had NaN-values in it so i modified the line to include int?-valuesit as well.

Thank you for the PR!

You ported the master-version of the sample which works but isn't optimal since we are still using Chart.js 2.9. Could you adjust the config to the according sample (note the 2.9 branch instead of the master branch)?

Apart from that there are some whitespace issues and I have left additional comments for further improvements :)

This should stay two-space-indented. You might need to edit this file outside of Visual Studio, it can mess with the json indents :/

[andreassundstrom]

I think the problem is in .editorconfig, it has default to indent_size = 4. Is it ok to add:

[samples.json]
indent_size = 2

I will regardless of course edit the file to have correct spacing.

Thanks for feedback @Joelius300. Sorry for the misses in indentation, that was sloppy of me. I've tried to correct the PR according to your comments. I left a question about the .editorconfig, if you don't want it I can remove it from the PR.

Best regards
Andreas

Hey @andreassundstrom

It looks pretty good and I'm really sorry to just leave you hanging here but I'm leaving this community. Thank you for your understanding.
I can't tell you what will happen to your sample but feel free to leave this PR open, maybe someone will find it useful ❤️
