Summary

In this article, we discussed how to create a custom stock chart based on the cartesian coordinate system. We implemented a custom chart, series, and a sprite for a MACD indicator that is commonly used by Stock analysts. The implementation demonstrated Sencha Charts' important classes, their responsibilities, interactions, and how you can create a custom chart. Subsequently, you learned how to use the newly created cartesian custom stock chart in an Ext JS 5 application.

Next, we will see how to create a custom polar chart and use it in our application.
