In MapInfo 10.0, how can I quickly colorize point symbols according to a field in the data table, without creating a new map? My data is just longitude, latitude and time, and I'd like to colorize the points according to the time field. This seems really basic but I can't find any way to do it.
what i understand from your question is that you want to create points thematic,changes both symbol size and color.
you can do it as :
1.Map > Create Thematic Map
2.Select Point Ranges Default from template
3.Click Next and select a table and a field.
4.Select your Ranges...
The result will be sth. like this. you can more info here.
i hope it helps you...
