thematic symbology issue

[Peter Horne]

Hi, using Version 2023 Build 142. 

I have a simple thematic layer (Individual value) with 3 symbols on a native MI table.

Some of the points are coincident, and maybe all 3 species were caught at that site, hence needing a different symbol.  If you look at the attached images it seems that the thematic symbol appears for only the "top" record for coincident points. Look at the bottom right of the image(S) - If you switch off Ae aegypti (small red dot) the large green dot appears. This behaviour is happening all over the map depending on what you switch on or off. Obviously I want ALL 3 symbols turned on. I have not encountered this behaviour before for thematics. Is there something I'm missing?? 

Any help appreciated.........Short of pulling out the different species into their own tables, which seems overkill, I am not sure what else to do.

Thanks

Hey Peter

I’m guessing it’s Fast Symbol Rendering that prevents all the symbols from being rendered

thanks so much Peter. Problem solved by turning off Fast Symbol Rendering.

Hi,

how about duplicate the layer 3 times and keep each visible case in each layer ?

Best regards,
