  * Please keep pull requests concise, and document new functionality in the relevant .md file.
  * Consider whether your changes are useful for all users, or if creating a Chart.js extension would be more appropriate.
  * Please avoid committing in the build Chart.js & Chart.min.js file, as it causes conflicts when merging.
+ * Please submit your pull requests as one commit, if necesary please ```rebase``` to make it a single commit.
