I really like both Simulink Data Inspector and the new Signal Analyzer App for comparing and analyzing signal data. They make it easy to rapidly compare lots of signals, and with the Signal Analyzer to see the spectrum and spectrogram in the same window as the signal. Additionally, they also have data cursors that allow me to scan the values of multiple signals at the same time. Here’s a screen shot of all of the features I just mentioned:
So what if you want a data cursor on a regular MATLAB plot? Well now you can with Marjorie’s cursorbar. Cursorbar gives you plenty of control over its appearance and behavior to meet all of your data cursor needs.
Look at the help for a whole slew of examples! Here’s the 9th one:
% Create line plot x = linspace(0,14,201); y = sin(2*pi*x/3); h = plot(x,y,':k','LineWidth',2); ylim([-1.2 1.2]) % Define colors topMarkers = 'x+*o.sdv^><ph'; % top marker styles bottomMarkers = 'x+*o.sd^v<>hp'; % bottom marker styles targetMarkers = '+xo*.dsddddhp'; % target marker styles lineColor = lines(13); % cursorbar colors % Create cursorbars for ii=13:-1:1 c(ii) = graphics.Cursorbar(h,'Location',ii); % c(ii).TopMarker = topMarkers(ii); c(ii).BottomMarker = bottomMarkers(ii); c(ii).TargetMarkerStyle = targetMarkers(ii); % c(ii).CursorLineColor = lineColor(ii,:); c(ii).TargetMarkerEdgeColor = 1-lineColor(ii,:); % c(ii).TopHandle.MarkerSize = 12; c(ii).BottomHandle.MarkerSize = 12; end % set(c,'ShowText','off','TargetMarkerSize',12,'TargetMarkerFaceColor','w')
