Printing Template - Dynamic Legend

[Anonymous User]

Original User: gabrielnespoli

Hi everyone,

I am not quite sure if this is the right sub-forum. Sorry if it is not.


Lets go to the point..I know how to define a dynamic legend to a map, there isn't problem with this and it works fine:

But, the problem happens when I try to publish a printing template. In templates, there isn't layer in the .mxd, so when I try to check "Only show classes that are visible in current map extent, this checkbox isn't editable, because in templates the map doesn't have any layer:

The result of not setting the legend dynamically is this:

As you can see, the legends of all layers are displayed, even the ones that are not in the map extent.


So, if anyone knows how can I set dynamic legend to printing templates, help me please!

Hi Gabriel,
the problem is that the proprerty "visible in current extent" is a layer proprerty, not a legend proprerty. So, in yuor geoprocessing model, after you load layer in MXD document and before export map as PDF, you have to loop throught every item in legend and set property "use_visible_extent" to TRUE, with a code like this:

for lyr in legend.listLegendItemLayers():
     legend.updateItem(lyr, use_visible_extent = True)
