URL drill-down is the act of clicking on a series data point and being directed to
a URL that brings related information. JetChart applets support drill-down through
the use of parameters to specify a list of associated URLs.
The table below lists the parameters to be used with JetChart applets to implement
URL drill-down:
Applet | Parameter | Usage |
GraphApplet.class and ScatterApplet.class | seriex_urls | Specify a list of URLs associated with a series data points. |
GraphApplet.class and ScatterApplet.class | seriex_urlcontext | Specify the context in which to interpret a relative URL. |
GraphApplet.class and ScatterApplet.class | seriex_urltargets | Specify URLs targets. |
PieApplet.class | urls | Specify a list of URLs associated with a series data points. |
PieApplet.class | urlcontext | Specify the context in which to interpret a relative URL. |
PieApplet.class | urltargets | Specify URLs targets. |
The names of absolute URLs must be well formed, including the protocol used to load documents, as in 'http://www.jinsight.com/jetchart/index.html'. It is also possible to inform only relative URLs, provided the URL context be passed to one of the url context parameters above listed. For instance, the URL previously mentioned can be split into two strings, as below:
<param name="serie1_urlcontext" value="http://www.jinsight.com/jetchart/">
It is more advantageous to specify relative URLs in that it is not necessary to repeat the URL context
for each series data point, especially if a series has a great number of values.
The follow example displays a blue bar series and URL drill-down is activated. A click on any bar
loads an associated website.
