HEC-MetVue allows for plotting time series for both points and polygons selected in a Map Window. This allows for comparing the temporal distribution of meteorological data between different geographic locations and/or areas. When there is data loaded into the Map Window, these plots can be accessed through the right-click context menu as shown below:

1

Right-click option to plot time series sampled at cursor's location in the Map Window

2

Right-click option to plot time series sampled for a polygon area  drawn in the Map Window using Creating a Polygon With the Define Polygon Tool

Time Series From Points

When the "Plot Time Series For Point" option is clicked, HEC-MetVue samples the value for that location in each TIN/Grid loaded into the Map Window. After processing these values, the time series is plotted in a new dialog, and a corresponding point is displayed on the Map Window, identifying the location from which the time series was sampled. This is illustrated in the image below, where time series from two points were processed. Labeling on the Map Window is consistent with labeling in the plot, identifying each point from which a corresponding time series was sampled.

Additionally, any time series can be removed from the plots by right-clicking on the curve (see below), which would also remove its associated point display in the Map Window.  If the plot is closed, all time series in the plot and all their associated point displays in the Map Window will be removed.

Time Series From Polygons

After creating a polygon in the Map Window, and subsequently selecting the "Plot Time Series" option in the "Ad Hoc Polygon Operations" menu, the average value within that polygon will be computed for each TIN/Grid loaded into the Map Window. Then a time series plot will be created, and the polygon will become persistent in the Map Window.  The Ad Hoc Polygon Operation functions similar to plotting time series from points, and plotting times series from polygons can be used in conjunction with plotting time series from points. Below is an image showing the result of plotting two polygon average time series.
