Include "a" character in a wordcloud

3 views (last 30 days)
I am just trying to plot a simple wordcloud of grades which has a grade string, say,
when I plot it using,
the function removes all Grade A information. How do I include the grade A in the plot?

As far as I know, the wordcloud function normally does not count the prepositions. I believe since the alphabet A is a preposition, the count for this letter does not happen. Just guessing, else it should have counted all letters in the first place.
Hence, I am looking for a possible solution to count this letter or any specific letter or a word in general. It would solve the issue.

Function takes column matrix. That's why!

Bear in mind that this is with base matlab. The text analytics toolbox, which I don't have, may have some better ways of doing what you want.
I'm simply converting your char array into a categorical array. It doesn't look like wordcloud does any filtering on categorical arrays:
