<H2><A NAME="6_2">6.2 Specifying targets for image map plots</A></H2>
<P> To turn a standard image script into a CSIM script the first thing
 needed to do is to supply the appropriate URL targets for the hotspots
 in the image.</P>
<P> What the hotspots represent depends on the type of plot you are
 doing. The following plot types and graph areas support image maps.</P>
<UL>
<LI> Line plots. Markers are hotspots.</LI>
<LI> Scatter plot. Markers are hotspots.</LI>
<LI> Pie Plots and 3D Pie plots. Each slice is a hotspot</LI>
<LI> All types of Bar graphs. Each bar is a hotspot</LI>
<LI> Legends</LI>
<LI> Text strings, for example titles and title of axis</LI>
</UL>
<P> To specify a link for each hotspot you have to use the <A href="../ref/Plot.html#_PLOT_SETCSIMTARGETS">
 SetCSIMTargets()</A> method for each plot (or specific area) in the
 graph which should be a hotspot.</P>
<P> There are two arguments to this method</P>
<OL>
<LI> $aTargets, an array of valid URL targets. One URL per hot spot, for
 example if you have a 10 values bar plot you need 10 URLs. If the
 SetCSIMTarget() is applied to, for example, a text then of course only
 one URL target should be specified.</LI>
<LI> $aAlts, an array of valid alt-texts. Many browsers (but not all)
 will show this text string if the mouse hovers over a hotspot.</LI>
</OL>
