so if you are wondering if there is a cheat sheet like that made for ukulele, then i dont know. but wouldnt you rather be able to eventually figure it out in your head on your own, rather than look at a sheet everytime you needed to use it? im not saying a cheet sheet is bad. but by learning this, you wont need one. but if you really want to... make one of your own. by drawing out the fretboard in the same way (four lines instead of 6) as that pic you posted, and plotting the positions out, it will help you learn it quicker (i have my students do the same thing).
