SWT-Chart example problem to execute

Hello,

I checked out SWT-Chart with the following command:

Then I imported org.swtchart.ext in my eclipse's workspace, but I am not able to run it, because I can not find the class which contain the main method.

How is it possible to run this example?

Thank you in advance.

Checkout org.swtchart.examples/, it contains lots of examples that can be run.
Or, write your own examples that demonstrate the usage of code you already have.

org.swtchart.examples are working, but they do not have any examples eg. how to zoom or select and therefore I tried to get org.swtchart.ext running.

Is there any reason why org.swtchart.ext does not contain any main method?

The source code is (probably) intended to be used as a library.
It's like when you develop separate component (of any kind), you certainly won't put main method inside your code; you can additionally provide some examples as separate classes, which is the case here, to demonstrate some of the functionalities your component provides.

The code looks very well documented, so I think it won't be too difficult to write an example on your own for the functionality you want to examin.

EDIT: There is an example provided in org.swtchart.examples.ext/ that you can further modify, but you should be familiar with plugin development.
