The ease of use and customization of the charts. The support of Angular2 is also great. I haven't found anything that I dislike. I have been using ng2-charts for a while now and have not encountered any problems. I am using this for a project that I am working on and I am very happy with the results. I am currently working on a project that is using Angular2 and ng2-charts. I am using ng2-charts to make charts for my project. I like the fact that I can use the library with a few lines of code. The documentation is clear and concise. The library is easy to use. I dislike that the library is a little bit outdated. I think that the library should be updated and have a more recent version. I use the library to create a chart with Angular2. I used to use the library for creating charts with AngularJS. It is very easy to use and works well.
