Please do not add promotional material to Wikipedia, as you did to Box plot. While objective prose about beliefs, products or services is acceptable, Wikipedia is not intended to be a vehicle for soapboxing, advertising or promotion. Thank you.
Your edits also have a conflict of interest. You should get a consensus on the talk page before adding such material.
Your edits are more about how to do something rather than technical content. Wikipedia is WP:NOTHOWTO to do something. It is an encyclopedia.
Your link does not contain significant material that is not already in the article. Generally, external links should have information that belongs in the article, but has not yet been added. WP:ELNO
Generally, material in someone's blog is not considered a reliable source.
Do not add this material again unless you raise a discussion about it on the talk page and get a consensus to add the material. If you add the material without going through those steps, you may be BLOCKED for slow edit warring or disruptive editing.
