A sample isl script:

<isl debug="true" offscreen="false">
    <property name="dataTime" value="2010111013"/>

    <procedure name="mkT">
        <!--center useprojection="false"/-->
        <display type="planviewcontourfilled"  param="${ele_name}" >
            <property name="id" value="display1" />
            <property name="displayCategory"  value="Basic"/>
            <property name="colorTableName"  value="Temperature"/>
            <property name="colorScaleInfo" 
value="visible=true;orientation=vertical;placement=left"/>
            <property name="settingsDisplayUnit"  value="c"/>
            <property name="displayListTemplate"  
value="%timestamp%-%longname%"/>
            <property name="displayVisibility"  value="true"/>
            <property name="contourInfo"  
value="interval=4;min=-40;max=140;base=-28;dashed=false;labels=false"/>
            <property name="useProjectionFromData" value="false"/>
        </display>
        <display type="planviewcontour" param="${ele_name}">
            <property name="id" value="display2"/>
            <property name="displayCategory" value="Solid"/>
            <property name="colorTableName" value="Red"/>
            <property name="contourInfo"  
value="interval=4;min=-40;max=140;base=-28;dashed=false;labels=true"/>
            <property name="useProjectionFromData" value="false"/>
            </display>
        <pause/>
        <image file="${islpath}\${dataTime}.png"/>
    </procedure>
    <bundle file="${islpath}\china.xidv" clear="true" >
       <setfiles datasource=".*" file="${islpath}\china.nc" />
    </bundle>
    <mkT dtype="ele_hours" area="china" ele_name="t"  />
    <removeall/>
