Chart Maker - Graph create app

Wanted an app that would allow me to create line graphs with 5 data sets on one graph, to compare/monitor daily weight gain in a litter of abandoned kittens. Unfortunately, cannot put more than one data set into a graph, entry is not entirely intuitive (although not hard to figure out) and automatically adds each data point, totaling daily weights, for some odd reason. But it was free and doesn’t have annoying pop-ups. I just need to look at each kitten’s graph separately and manually look at each line graph after each day’s entry.

Hi,I just got this app a day ago and I want to say that it has not been great because every single time I open the app it glitches and I really don’t like how the app does this and I just want to say you guys really need to fix this.
