Sorry for asking such a basic question - when I'm creating graphs in graph builder, the data points start out "greyed out." Sometimes I can just click somewhere on the graph to allow the data points to show their "full color," but sometimes that just doesn't work. I can click on individual data points to show their full color. Any suggestions?
Most likely you have selected one or more rows in your dataset. Since everything's connected the selected dataset rows will be highlighted in your graph. Make sure nothing is preselected in your dataset when you make your graph. Or click on Rows > Clear Row States.
