Thank you Anita and Giovanni, I tested what you described and observed the expected behavior. --Lee<br><br><div class="gmail_quote">On Mon, Mar 5, 2012 at 1:19 PM, G. Allegri <span dir="ltr"><<a href="mailto:giohappy@gmail.com">giohappy@gmail.com</a>></span> wrote:<br>

<br>Add map item (A). Check "Lock layers for map item".<br>
Add map item (B). DO NOT check "Lock layers for map item".<br>
Change symbology in main QGIS window.<br>Add map item (C).<br><br>A and B
display old symbology. C displays new symbology. But if you make more
changes to the symbology, and want to update C, you have to hit Refresh
view button. Now, *all* map items, whether or not "Lock layers for map
item" is checked, change to new symbology. Similarly, if you change the
layer extent in A or B, they update to display the new symbology.<br>
<br>So it looks like if you add a map item, it will not update as long
as you leave it alone and don't hit Refresh view. But then if you're
unhappy with map item C, you have to delete it and add it in order to
avoid hitting Refresh view. Furthermore, I don't see any difference in
behavior between A and B. So what does "Lock layers for map item"
actually do?<br>

I've used QGIS to create a layout with a main map and an inset (e.g., Continental US with Alaska and Hawai'i as inset maps at different scales). But that's just two "viewports" onto the same underlying data. I wanted to make a layout where the same area would be displayed with two different symbolizations, side by side on the page for comparison. For those familiar with ArcGIS, I would normally accomplish this with two Data Frames.<br>
<br>Is there any way to do this with QGIS? Or do I have to create two QGIS projects, and combine the maps externally (presentation software, page layout software, etc.)?<br><br>Thanks,<br>--Lee<span><font color="#888888"><br clear="all">
