Hi,  
whenever I write a script in any of my components I have to guess hot to access data, components … So Do you have any document with the Jython Ignition API for components scripting ?

For instance, I wanna have a bottom under an easy chart which may dynamically change ChartMode historic/real  
Another example, I wanna have my own Chart with 3 inputs ( start/end/groupedByUnitTime )  
…whatever …so any document with such API reference ?

Thanx

The online user manual for Ignition has appendices for expression and scripting functions:

With your specific examples, you’ll want to look into using property binding before using scripting. If you’re not familiar with property binding you can find a section detailing binding in the manual as well.
