Graphs Generator listener doesn't really care about the nature of the Sampler, it should produce charts no matter of which Samplers are used (as long as they deliver sample results)
The problem is somewhere else, if you pay attention to this red 1 next to yellow exclamation sign at top-right corner of JMeter GUI
it indicates that at least one error happened during your test so it worth checking jmeter.log file, most probably you will find the reason (or at least a clue) there.
Looking at my crystal ball I can see that you don't have Synthesis Report plugin installed which is kind of pre-requisite for the Graphs Generator so my expectation is that if you install it using JMeter Plugins Manager it should resolve your issue.
I would also recommend re-considering the approach to running your tests, GUI mode is supposed to be used for tests development and debugging only, when it comes to tests execution you should run JMeter in command-line non-GUI mode.
And last but not the least, I don't think this Graphs Generator listener adds a lot of value, you can get much better view if you generate HTML Reporting Dashboard
