+
+        Also try to search for your issue - it may have already been answered or even fixed in the development branch. However, if you find that an old, closed issue still persists in the latest version, you should open a new issue using the form below instead of commenting on the old issue.

+
+        An important design goal of ECharts is keeping the API surface small and straightforward. In general, we only consider adding new features that solve a problem that cannot be easily dealt with using existing APIs (i.e. not just an alternative way of doing things that can already be done). The problem should also be common enough to justify the addition.

+
+        An important design goal of ECharts is keeping the API surface small and straightforward. In general, we only consider adding new features that solve a problem that cannot be easily dealt with using existing APIs (i.e. not just an alternative way of doing things that can already be done). The problem should also be common enough to justify the addition.
