In an AutoHotkey webinar a few years back I demonstrated how to easily create Bar Charts with AutoHotkey
I went back and excerpted the content which you can watch the below video to see just how easy it is to create bar charts with AutoHotkey! You can see the original post (with lots of examples & documentation) from Learning One on the old forum or jump to the continued thread on the new forum (but not many resources).
BTW- if you’re wondering how to save the image as a file (for use in other tools) you can see this post where he shows how to save the graph as a PNG
