How would you translate the chart in this DOCX file?

Can anyone tell me quickly the best way to translate the chart in this DOCX file? Or how to get an accurate word count of the words to be translated in the file?

I love to see the different approaches people take to this problem. It's one which I think is encountered with some frequency by translators, and in the past I too many different approaches to it - long ago I usually did something involving PDF conversion, editing of the PDF and making a screenshot. But that is inefficient and doesn't allow the use of CAT tools.

Yesterday I picked up a project with 18 of those silly charts embedded in it. A real nuisance. Here's what happens if you try to edit one of those charts in situ:

Hopeless, right? A lot of very authoritative web pages make it clear that without having the linked Excel files, you cannot modify the text. Not true, actually. With or without hints, a number of technically versatile colleagues found ways to solve he problem or at least made close guesses. Some of these are here in the comments. One very interesting exchange on Twitter showed than somehow the settings of the OmegaT import filters can be tweaked to solve this:

 

The thing about OmegaT is that it's sort of geeky - the solution looks pretty good here, but I can't actually make it work myself.

The solution I worked out last night is very similar to the one described by Stanislas in the comments.

1. Change the file extension to ZIP
2. Look inside the ZIP file with Windows Explorer or another suitable tool as described in other blog posts.
3. Inside the "word" subfolder there is a folder named "charts". It contains XML data with all the chart headings, numbers and labels. Copy it.
4. Paste a copy of the folder where you want your source files. Import the chart XML files into any CAT tool or XML editor. It's a good idea to configure a filter to exclude and protect the references to the original Excel files with the data. (Though I am curious whether deliberately spoiling these data can protect against the unwanted update that one person worried about in the comments. I'll have to try that.)
5. When the translations are completed, paste the XML files back inside the charts folder in the file structure.
6. Rename the extension back to what it was at the start (DOCX in this case). You're done. No refresh necessary (unlike with embedded Excel or PowerPoint objects).

A memoQ filter configuration for these XML files can now be found on Kilgray's Language Terminal.
