Why do the Xs marking high/low temperatures in the weather graph sometimes not match up with the curve of the graph?
You will sometimes notice this when using very long graph periods, such as viewing 2 months of data at a time. This occurs when there is more than one weather data point (often many data points) that fall on a single pixel on the graph. If this is the case, Seasonality will average those values and display the average on the graph at that point. When there is a high or low temperature at that point, many times the average will be much higher or lower and will not match up with the X on the graph. As you reduce the amount of time shown horizontally on the graph, the curve should get much closer to the X marking the high or low temperature.
