            <P>If a chart's source is dynamic (changes over time), some browsers 
            might download only one instance of the source file, cache it, then 
            display the same chart repeatedly. To prevent browsers from caching 
            a dynamic source file, append any unique value to its URL to keep it 
            new. This value must be added programmatically to change with every 
            page reload. This could be the time in microseconds, or any random 
            number:</P><!-- PHP -------------------------------------->
