One such example of this is with the charting library we use on Coinigy. We license access to the code for the charting library, and display our own data within that code. Our licensing agreement forbids us from modifying this code, and there are a few known issues with certain features in some browsers. However, the library we use is currently the best web-based charting package available, and we are constantly re-confirming that is the case in in our on-going quest to provide the best possible platform.
Coinigy strives to provide an exceptional experience for all of our users. However, on some occasions, users have had to make sacrifices on the browser they use to access Coinigy in order to have this experience. Chrome is the best browser to use. Firefox works great too. Newer versions of Internet Explorer also work.
