the option "land fill style" of RDB data is not work

Dear all,

There are two data types in our LAS site, NetCDF and RDB (MySQL) data.

When I select NetCDF data, I can change the "land fill style" option to "Outline", and get a contour output.

But if I select RDB data, it's no "land fill style" option.

Therefore, I modified the insitu_options.xml file as following.

<optiondef name="Options_insitu">
 <option>
 <help>Chose the image format.</help>
 <title>Image format</title>
 <menu type="options" name="insitu_image_format">
 <item values="default">Default</item>
 <item values="gif">GIF</item>
 <item values="ps">PostScript</item>
 </menu>
 </option>


 <option>
 <help>Style for drawing continents. Only applies to XY plots.
 Choices are:
 <ul><li>Default -- let LAS decide
 <li>None -- don\'t draw continents
 <li>Outline -- draw continent outlines
 <li>Filled -- draw filled continents
 </ul>
 </help>
 <title>Land fill style</title>
 
 <menu type="options" name="insitu_land_type">
 <item values="default">Default</item>
 <item values="none">None</item>
 <item values="contour">Outline</item>
 <item values="shade">Filled</item>
 </menu>
 </option>
</optiondef>

After refresh MetaData DB, I can choose "land fill type" option to "Outline" with RDB data,

but the result output is the same.

This had no effect.

I also tried to add following line in RDB's dataset XML file.

<properties>
<ui>
 
 <default>file:ui.xml#insituProfile</default>
</ui>
<land_type>contour</land_type>
<database_access name="MySQL">
 <db_type>amdp_2_tables</db_type>
 <db_name>amdp</db_name>
 <db_title>temp</db_title>
 <db_host>172.16.20.35</db_host>
 <db_login>guest</db_login>
 <db_passwd></db_passwd>
 <db_table>lusd,lusm</db_table>

But it's also not work.

My question is how to produce contour GIF file of RDB data?

I think these are Ferret parameters, how do I modify it?

Thank very much.
