Thank you for pointing out something I found before and ... scared me away ;-) This looks way too complicated for me and I'll live without it I guess. As a matter of fact, since I'm struggling with my items to display, I was thinking to do a one-off chart and update it each time I have new data (not keeping the past). While adding the % sign was a breathe with line charts, with polarArea since it's not longer the label being changed, but the data coming up on the tooltip, I haven't been able to achieve the same result. Well... let's see if after a good night sleep, light comes to me. :-) Thank you. |

Since I'm asking questions...
My chart displays a percentage. I managed easily to add the % unit in the tooltip after the value. I was wondering how I could add the 2 values the %age is calculated from below. Something like:
Item: 20%
Buying: $80
Selling: $100
Thank you.
Fred
