Hi,
I have a shape file which has colum1,column2,column3... I want to create a thematic map based on the values of following calculation:
Column1 * PARAMETER -Column2
The "Parameter" will be read from user's input. So I can't add a column to store the values in advance. The thematic map will have 5 bands, say
<0,
0-20,
20-50,
50-100,
>=100
Any ideas how to implement this?
Thanks in advance!
Rose
