This might be a bit of a strange question and hopefully someone can just point me straight at some documentation. I want to visualize on a text field where I know that part of the message will contain a fixed string (from a small collection of strings, e.g. INFO, WARN, ERROR, CRIT, DEBUG). Ideally I'd like to be able to create a Pie Chart for this to show percentages of each of the types of collection. Can someone point me to or provide me with a simple concise method for doing this?
