This command will add the object as a “prototype” and use the text as the title next to it. The text must be unique for a given legend.<br> + * legend.remove(text) will remove the object labeled by text from the legend<br> + * legend.removeAll() removes all objects from the legend<br> + <br> + As of the 0.6 release of GUESS we also include a special GradientLegend object to visualize continuous data. The syntax for this GradientLegend object is:<br> + <br> + {{{GradientLegend(start_color, end_color, min, max, tick_mark_every)}}}<br> + <br> + The visualization will show the min and maximum value with a tick mark every tick_mark_every units. The following code generated the figure below:<br> + <br> + {{{<br> + colorize(freq,red,yellow)<br> + GradientLegend(red,yellow,freq.min,freq.max,10)<br> + }}}<br> + <br> + --&gt;<br> + [[Image(grad.jpg)]] &lt;--</span> </td> </tr> </table> </div>
