[Mapserver-users] How to add text to a legend

[Attri, Abhishek]

There is one layer, and two classes. All are set to "ON". Everything
works right except the legend. I get only one legend image for two
classes, and also the legend text is missing.

Here is a sample of the code I am using to create layer, legend, and
classes:-

// create a legend
    $map->legend->set(keysizex, 12);
    $map->legend->set(keysizey, 12);
    //$map->legend->imagecolor->setRGB(200, 225, 124);
    $map->legend->label->set(type, MS_BITMAP);
    $map->legend->label->set(size, MS_MEDIUM);
    //$map->legend->label->set(font, test);
    $map->legend->label->color->setRGB(0, 0, 89);
    $map->legend->set(status, MS_ON);
    $image2 = $map->drawLegend();
    $image_url2=$image2->saveWebImage();


// create layer
        $layer = ms_newLayerObj($map);

        $layer->set(name,"county");
        $layer->set(type,MS_LAYER_POLYGON);
        $layer->set(status,MS_ON);
        $layer->set(data,"counties");
        $layer->set(tolerance,10);
        $layer->set(classitem,"POP_2000");

 // create class1
            $class1 = ms_newClassObj($layer);
            $class1->set(status, MS_ON);
            $class1->set(name, 'myclass');
            //$class1->set(title, test1);
            $class1->setexpression('([POP_2000]<50000)');
                // create style
                $style = ms_newStyleObj($class1);
                $style->color->setRGB(255, 185, 15);
                $style->outlinecolor->setRGB(0, 0, 0);

// create class2
            $class2 = ms_newClassObj($layer);
            $class2->set(status, MS_ON);
            $class2->set(name, 'myclass2');
            //$class2->set(title, test2);
            $class2->setexpression('([POP_2000]>50000)');
                $style = ms_newStyleObj($class2);
                $style->color->setRGB(139, 0, 0);
                $style->outlinecolor->setRGB(0, 0, 0);

Please help me understand what I am missing here.

With thanks in advance,

-Abhishek

The CLASS NAME is the text used for the legend text, so what you
describe doing should work.  In mapscript you must make sure to set the
status of each layer to MS_ON first.
