Q: Why does not the Thematic Map Display in iServer, but the Parameter is Correct and there is a Return Result?

A: Possible reasons are in the thematic map setting. Please pay attention to the description of the class references. For example, the statistic thematic map height and width unit is consistent with the map unit; latitude and longitude unit is in degrees; the projected coordinates is in meters; no projection is the other; If it is a projected coordinate map, but the icon height and width is configured according to the longitude and latitude map, then the icon will not be displayed because the size us is too small.
