Also, changing the topic to the other method - involving the 'Constellation Object' block for generating constellation diagrams ---- I now know why I get a spread of points across a line. I notice that if I have a Vector Source that repeatedly outputs the value '3', which means outputting a 3, then another 3, then another 3 etc ....... then the associated complex value (that was assigned to '3' in the Constellation's Symbol Map) --- such as 1+1j (which is expected), but the next plotted point will not be 1+1j (associated with the next '3'). Instead, the Constellation plotter appears to jump back to the same initial starting point. So rather than plotting multiple points of 1+1j, the constellation plotter keeps jumping back to an initial starting point (consistently the same starting point) before plotting the next 'expected' complex value. I don't know why it does that yet. This is where I need more help too! Thanks again!

Update - I found path for getting a constellation diagram. But haven't figured out how to use that properly yet as well. The other path is using a Constellation Object, where an online tutorial had this Symbol Map for the constellation : [0, 1, 3, 2] and the corresponding constellation points defined within the Constellation Object block are : [-1-1j, -1+1j, 1+1j, 1-1j]

I'm just focusing on getting a simple binary stream together, such as '110100' (repeated) .... so it just goes '110100110100110100.......' and then to see whether I can generate a simple QPSK constellation map.

I don't yet understand exactly what to do in order to get that QPSK constellation map. But I've taken steps to string some blocks together - just to try something at least.
