Hi all, I am trying to learn the processing language and I am stuck with this tutorial where I am supposed to design a couple of charts, I designed the 2 charts using rect(), but I didn't know how to make it transfer from one bar to another, let's say the first bar refer to January and the second to February, on clicking something on the image it will transfer to the first bar and if I click again it will transfer me to the second bar, someone suggested using draw(), but really could't get the hang of it, any suggestions or advice will be really appreciated, I really don't know where to start with processing, anyone out there wanna help?!!!
