Custom Layer Legends

Last updated 7 months ago
Contents

The legend for a layer can be customized to match your custom style, (or the style of your website).

Legends use standard HTML notation. Quick Intro to HTML​

Default Legend Code

Here is an example of the default legend for a point layer colored red:

div class="omh-legend">
 <div class="point" style="background-color: red">
 </div>
 <h3>{NAME}</h3>
 </div>

Graduated Circles Example #1

In this example we are using the grid design from http://materializecss.com/grid.html which is the UI design library used by MapHubs and is automatically available.

<div class="omh-legend">
 <h3>{NAME}</h3>
 <style scoped>
     .icon-col {
        width: 24px !important; 
        height: 100%;
     }
 </style>
  <div class="row no-margin" style="height: 14px;">
    <div class="col icon-col s2 no-padding valign-wrapper">
         <div class="col s4 no-padding circle valign" 
            style="background-color: red; width:4px; height: 4px">
