Points not getting drawn if there are lot of error values represented by NAN in MATLAB 2015a.

We are trying to plot a set of data samples that has more error values represented by NAN. We are able to see the plot as scattered points in version 2014a but in version 2015a the plot displayed will be empty. Attached is the sample data set that we are interested in plotting. Steps we are using for plotting: 1) Get subplot lines and axes reference using "plotyy" call. 2) Update axes properties. 3) Get continuous data at 25sps. 4) Push data to buffer. 5) Update subplot lines with buffer data. 6) Use "Drawnow" command to draw subplot data.

Why can't you share actual code? Might it be possible to share a MWE that reproduces the problem?

*We cannot share the actual code.*

Then it is not legitimate to pose a question too.

figure,plot(dummy_data)

Would draw lines between consequent datapoints, it cannot draw any lines, since all datapoints are followed by NaN values.

You can plot individual points like this:

figure,plot(dummy_data,'+')

Or remove NaN values like this:

dummy_data_without_NaN=dummy_data(~isnan(dummy_data));
figure,plot(dummy_data_without_NaN)
