No code this time around. I’ve successfully created some graphs in canvas which pull from a mySQL database.
My question is, how would I go about displaying the data values along the graph? Is it possible?
Not looking for anyone to write me code. Just a helpful tip in the right direction.
Thanks in advance.
You can reference https://developer.mozilla.org/en-US/docs/Drawing_text_using_a_canvas to draw text on the canvas itself.
Or you can get the x,y positions and used
position: absolute;DIVs or the like to overlay tooltip like information on top of the canvas.Edit: Agreed on Shmiddty’s comment, this is probably all more a job suited to SVG’s strengths. See gRaphael for a vector graphing polyfill if you are interested.
