Multi-Variable History Chart
Many products include Multi-variable History Charts. This type of chart features a selectable history mode that tracks and displays the changes in conditions for more than one type of data over an allotted time period.
Examples of the type of information that multi-variable charts track include barometric pressure, temperature, humidity and wind speed. You can easily toggle between the multiple charts and readings. The charts allow you to monitor the rate of change over time up to the current time (typically the last 12 hours: -12, -6, -3, -2, -1, 0). An example of a multi-variable chart is pictured on the right.
