I'm not able to reproduce the problem: I get the watermark in both png
and pdf output. This was with git master.
What version of matplotlib are you using? Can you send (off-list) the
png and pdf files so I can have a look at your output?

All the data continuously generated in your IT infrastructure contains a
definitive record of customers, application performance, security
threats, fraudulent activity and more. Splunk takes this data and makes
sense of it. Business sense. IT sense. Common sense.
