 Users are encouraged to define as many **point_data** array entries as needed to filter and plot the input observations in the way they would like. Each point observation is plotted using the options specified in the first matching array entry. Note that the filtering, processing, and plotting options specified inside each **point_data** array entry take precedence over ones specified at the higher level of configuration file context.
 
-For each observation, this tool stores the observation latitude, longitude, and value. However, unless the **dotsize(x)** function is not constant or the **fill_plot_info.flag** entry is set to true, the observation value is simply set to a flag value. For each **plot_data** array entry, the tool stores and plots only the unique combination of observation latitude, longitude, and value. Therefore multiple obsevations at the same location will typically be plotted as a single circle.
