For example, the percentage of returns filed on time is close to 100% and any variation when seen on a scale of 0-100% is very hard to see in a static image.
Er enghraifft, mae canran y ffurflenni treth a ffeiliwyd ar amser yn agos at 100% ac mae unrhyw amrywiad pan y’i gwelir ar raddfa o 0-100% yn anodd iawn i’w weld mewn delwedd statig.
