That doesn’t answer the question: “what text are you trying to show?”
Try sharing your code. You may be having language / character problems if the example text is English but you are using a different language.

Hmm, from the screenshots your letter “I” is always missing.
Wait, you are using Processing 1.5.1 ?? Hmm. That might have something to do with it. What version of ControlP5 are you using?

Was that cp5 version bundled with the plotter project, or did it tell you to download that version?

so no way for us to test anything?
( no link, no code zip… )
* * *
but i found a link to version what uses
Processing v2.2.1
> **[euphy/polargraphcontroller](https://github.com/euphy/polargraphcontroller)**

now the name is similar but i not know if that is the same project anyhow?
* * *
still as Processing 1.5.1 is available
[https://processing.org/download/](https://processing.org/download/)
we can not say you must update…
