Hi All,

If you `print dir(components)`, it will print out all the methods/attribute the component has.  
Where can I find the documentation for every one of them?  
Like now, I need to know what the chart.add() does and what arguments take.

Start with Ignition’s module [SDK JavaDocs](http://files.inductiveautomation.com/sdk/javadoc/ignition79/795/index.html), and then Java’s own [Swing JavaDocs](https://docs.oracle.com/javase/8/docs/api/javax/swing/JComponent.html).

And welcome to the underbelly of Ignition. Since it is Java under the hood, you’ll have to get familiar with Java’s object orientation – data types, subclassing/inheritance, overrides, etc. Also, if you use this stuff, and break your setup, please don’t whine about it. If it’s not in the Ignition User Manual, it ain’t supported.
