Displaying Suppressed Data on a Line Graph

I have a data set that displays a specific measure by year from 2000-2015. There is a binary column that is 1 if the data is suppressed and 0 if it is not. I want to display the data on a line graph and include the suppressed records, but i want the suppressed records to have either a different line type, symbol, color, or style to indicate it is suppressed. Is there a way to achieve this? Adding the suppress variable to the legend does not work because it will no longer be one coherent line, but rather 2 lines that connect to only the other respective suppressed or non-suppressed records. I have also tried overlaying a scatter plot and using the binary variable as a legend on that in order to get different color points on each node of the line, but with dynamically changing filters, the points from the scatterplot do not always stay on the nodes of the line, therefore overlaying the two does not work.
