Recreate diagrams/graphs in a specific and consistent style

Design details: Recreate diagrams/graphs in a specific and consistent style/format.

Currently I have 14 diagrams to be recreated, by close of business Wednesday 23rd Nov, 2016. They range in complexity and the sample I have provided is one of the ones I would describe as medium to complex, compared the the other 13 diagrams.

For my PhD thesis I cannot use scanned images of graphs or diagrams, because the lines and symbols become too "pixelly."

The guidelines to recreate these are...

Draw the figures directly in a computer, using preferably PowerPoint, Excel, or the drawing window of Microsoft Word.
Make sure the fonts and any symbols are big enough.
Do not make figures any wider than ~14 cm, because they need to be view-able in a Web-browser window without the reader having to scroll sideways.

Please do not hesitate to contact me if there is anything I have not covered or if you have any queries or questions.
Target audience: Academic
Ideas for the visual style: See design detail above
Preferred colors: Black and white only
Where the design will be used: In a PhD thesis initially. Later in academic journals and conference presentations.
