Dear @anildas ,

you are right, the current documentation is a bit light. The reason for this, is that this is a relativity new extension. So let me elaborate a bit on it.

The config file is a configuration json file which contains all information. Whenever you create a chart in RapidMiner's Studio Result view, you can store the configuration with the edit button on the lower left:

I would recommend to save the json file in the location of your repository, for example:

C:\Users\MartinSchmitz\.RapidMiner\repositories\Local Repository\Forum\Charting Example\static

We now can 'apply' our config to any data set, which has the correct columns. It can be the same data set, but it does not need to be.

This looks like this:

The purple object is a file object. Pretty much like a file you have on your disc. You can use a Write File operator to write it on disc or a store operation to write it into your repository. Alternatively the operator has a file option to directly write it to disc.

Note: In the current version of the extension the port may not be purple. Thats a bug and will be fixed soon

Using this with Send Mail

You can also use these file object as an input to send mail. This looks like this

Using this setup you attach the chart to your email. To the best of my knowledge you cannot embedd the images into the HTML, but only attach them.

Expert Tip - Macros!

You can also use macros within the config. If you for example use %{myTitle} as a title and have a macro called myTitle configured, then the Plot Data operator will replace it with the current value.

Cheers,

Martin
