Though aren’t widely used SVG Patterns are very powerful and light. Being vector graphics, a pattern adjusts very well to any screen resolution making the background crisp and nice. The only drawback would be is the lack of support on IE8 and lower and yes the lack of support in ExtJS 4.2.1 (and lower) too. Hopefully next versions of ExtJS will have within its SVG engine the needed piece which would allow us to add and use patterns in our ExtJS web apps.

Though ExtJS charts are very rich in features sometimes our clients want more. Very often they want some specific features which in the end leads to adding new custom sprites to the charts. And ExtJS is ready to help us with the needed tools to accomplish those features and make the client happy. In this post I’m going to add some light on how to add custom sprites in ExtJS charts based on a real world example.
