A new feature included in the QB Maps extension (ver. 6.1) is the map legend. This feature enables users to display a legend box on the map that gives a brief description of the different markers that are displayed on the map. By creating and passing the field ID of the Legend Properties field from your Quickbase app, users can enable its rendering on the screen. A checkbox is also displayed at the bottom of the location list that allows users to toggle the visibility of the legend. The following image shows an example of this scenario.
Format for the Legend Properties formula text field:
<Marker Type 1>|<Label 1>
\n<Marker Type 2>|<Label 2>
...
For example:
"D-Blue|Duplex"
& "\nC-Yellow|Condominium"
&"\nS-Green|Suffolk Rentals"
&"\nA-Blue|Airport"
&"\nR-Purple|Residential"
The \n should be included for each pin after the first. This separates each line in the legend.
Note
Due to display space constraints, this feature isn't available on the mobile version.
You can also include the hidelegend parameter to default the Show Legend checkbox to unchecked and keep the legend hidden when the map opens. Set the value to true to hide it.
Required parameters
You need to pass some parameters to show the legend on the map. The parameters needed for this are dbid, legrecid, and legendfid.
The dbid is the ID of the table that stores the legend field.
The legrecid is the record ID# of the record in that table that has the legend you want to use.
The legendfid is the field ID of the field that stores the legend in that table.
