The feature of the data that we may want to consider is that of time. A graph that recognizes this ordering and displays the change of the values of a variable as time progresses is called a time series graph. Suppose that we want to study the climate of a region for an entire month.
Bubbles are caused by air trapped under the polish that rises to the surface as it dries. You can minimize bubbling by cleaning your bare nails first with polish remover to remove any traces of dirt or oil that could prevent polish from adhering properly. Then be sure to always use a good base coat. If you have ridges in your nails (like me!), be sure to use a ridge filling base coat, since an uneven nail base makes bubbling more likely to happen. Finally, don't use old or thick polish. It's almost guaranteed to cause bubbles!
Main article: Paronychia. Hangnails can become infected and cause paronychia, a type of skin infection that occurs around the nails. Treatments for paronychia vary with severity, but may include soaking in hot salty water, the use of oral antibiotic medication, or clinical lancing. Paronychia itself rarely results in further complications but can lead to abscess, permanent changes to the shape of the nail or the spread of infection.
