How many highs and lows are measured and recorded?

Most other stations simply give you the current readings. If highs and lows are available at all, they are usually quite limited. Only Vantage Pro2 and Vantage Vue give you the highs and lows (and/or totals or averages) for just about all weather conditions, with time and/or date for the last 24 days, months, or years for Vantage Pro2, and current and last 25 days, months, or years for Vantage Vue. No other stations on the market even come close. And not only can you view the data numerically, you can also view on-screen graphs, for instant visual representations of long-term trends.
