Rotate text in Inkscape

I am preparing a figure where I need to label several violin plots. I do not have enough space under the figure to fit everything without looking cluttered. So, I want to make the labels slanted at 45 degrees. How to do it in Inkscape?

I searched a bit and found this excellent tutorial. So, what I need to do is:

• I have several words that I will rotate altogether, so select them first
  
• Go to Object -> Transform (or press Shift + Ctrl + M)
• Click the Rotate tab and specify angle degrees and direction
• Check Apply to each object separately

That’s it!
