I've become a firm believer in presenting dew point for the general public, rather than relative humidity. It better represents how the moisture level in the air makes people feel outdoors. I present both, but use a graph that shows dew point temperature on the same chart as the ambient temperature. The larger the gap between the two lines, the less oppressive the humidity feels.
If you look carefully at your own temperature and relative humidity graphs over daily cycles, they can almost appear as mirror images. The temperature rising in midday makes the relative humidity drop inversely, but it still feels just as humid to people outdoors in midday.
Of course, this is my perspective from the Philadelphia area, where weather presenters have always referred to the "Three H's" in the summer: Hazy, Hot and Humid. If you're in a drier climate, it may not matter to your needs at all.
