I have charts that have x and y data. Is there a way to somehow read the image via a script and grab the relevant data?
Example: X row at bottom of chart displays time in days. Y row on side displays a number, say 15 for example.
Is there a way to read that data using some library/helper?
Thanks!
You’ll need an OCR library/software to get the statistical data.
There is this:

But that might not work well.
You should probably find an CLI app that works well for you, and call it from PHP. I assume you are using linux. The exec command will work under Windows. See this comment for more details:
