Use isnan() on the original vector. This will give you logical vector, which tells you where the NaNs are. You can use this index to mark missing values in your plot.
You can't plot NaNs, but you can mark the values which you interpolated, so they stand out.
See my example:
% Creating variables
t = 0:1:5;
y_NaN = [10, 11, 12, NaN, 14, 15];
y = 10:1:15;
% Finding NaNs
idx = isnan(y_NaN);
% Creating plot
plot(t, y,"*") % Plot all the values
hold on
plot(t(idx), y(idx),"r*") % Plot the values which were previously missing
Hope I helped.
Edit: added an example

You are trying to put a nan at the location of nan rates. But those locations are defined by having a Rate of nan, so when you try to plot using those NaN values as the y coordinates, you are using nan as the y coordinate, and that will cause it to not be plotted.
In the below I substitute 0 for the missing y coordinate, and I switched the color to c to avoid conflict with the 'or' of NX,X
... there are a lot of locations. You should put in that fix I showed you in a different one of your questions.
