#!F-adobe-helvetica-medium-r-normal--18* #!N #!CSeaGreen #!N #!Rtmappng Modules: Using Map #!N #!EC #!N #!N The #!F-adobe-times-bold-r-normal--18* Map #!EF module maps one field of data onto another. The field to be mapped #!F-adobe-times-medium-i-normal--18* to #!EF is the first parameter; the field to be mapped #!F-adobe-times-medium-i-normal--18* from #!EF , the second parameter. In the most common use of this module, no other parameters are set: the positions of the first field are used as indices to the positions of the second; the associated data values from the second field are then mapped as new data values onto the first. #!N #!N Components other than #!F-adobe-times-bold-r-normal--18* positions #!EF and #!F-adobe-times-bold-r-normal--18* data #!EF can also be mapped to one another. #!N #!N #!I0 #!N #!F-adobe-times-medium-r-normal--18* #!N #!N #!I30 #!N 1. Open and execute visual program .../Map.net. In this example, wind values are mapped onto an isosurface of cloud-water quantity and the result is colored. In addition, wind values are mapped onto a probe point and displayed as text glyphs. #!N #!I30 #!N 2. Double click on the right-hand #!F-adobe-times-bold-r-normal--18* Import #!EF icon to open its configuration dialog box. The #!F-adobe-times-bold-r-normal--18* name #!EF parameter field contains a file name ending in "wind." #!N #!I30 #!N 3. Change "wind" to "temperature" and click on #!F-adobe-times-bold-r-normal--18* OK #!EF . #!N #!I30 #!N 4. Reexecute the visual program. The image is now a color map of temperatures on the isosurface. The number displayed is the data value of the probe point. #!N #!I30 #!N 5. To move the probe point, first select #!F-adobe-times-bold-r-normal--18* View Control #!EF in the #!F-adobe-times-bold-r-normal--18* Options #!EF pull-down menu. #!N #!I30 #!N 6. Next select #!F-adobe-times-bold-r-normal--18* Cursors #!EF in the #!F-adobe-times-bold-r-normal--18* Mode #!EF pull-down menu. The probe point appears as a small white square immediately to the left of the data value. #!N #!I30 #!N 7. Drag the probe point to reposition it, and then release the mouse button. The data value is updated and displayed next to the newly positioned probe point. #!N #!I0 #!N #!EF #!N #!N #!N See Map and Probe in IBM Visualization Data Explorer User's Reference. #!N #!N #!N #!F-adobe-times-medium-i-normal--18* Next Topic #!EF #!N #!N #!Ltplot,dxall83 h Modules: Using Plot #!EL #!N #!F-adobe-times-medium-i-normal--18* #!N
