dualcursor

Add dual vertical cursors to a plot.

Description

Dual cursors are useful for picking relative measurements off of a plot; for instance - calculate the period of a time series, or the relative amplitude of two frequencies. A picture's worth a thousand words, so take a peek.

Key Features:
 - Basic syntax: dualcursor on / dualcursor off
 - Extended syntax supports a high level of control
 - Works with live data streams
 - Works in GUIDE guis
 - Includes delta calculations (x2-x2, y2-y1)
 - Export selected region to a new figure or to the workspace

Neat program for interactive data exploration !

[Poh Chee Khun]

This is what I am looking for!

[Lisa Barker]

Works great

Very nice tool. Just what I needed for my data evaluation and extraction. Now it's as good as any simulation tool. Thanks for the tool.

[thomas toth]

my plot contains multiple data sets (used hold on). is there a way to set the cursors on two different graphs as data source?
eg. measure x/y difference between two points on two graphs (data) within the same plot. could maybe done using left/right click of mouse?

Cool Tool

[Frank Hart]

Not working for me. Shame, too, it could be so useful. I am using Matlab R11 (5.3), and
when I run the sample code and then call
dualcursor, I get this message back:

??? labelformatfcnh = @
                    |
Missing variable or function.

Syntax error in ==> C:\MATLAB_SR11\central\dualcursor.m
On line 147 ==> datalabelformatfcnh = @local_maketextstring;

excelent

[Friedhelm Steinhilber]

super!

[Tony Rainoldi]

works great

Excellent. Only 1 thing : When i compile a soft which calls dualcursor, it turns. But it canno't turn when i deploy the soft on target pc with matlab runtime. May be it's due to the crypto aspect of dualcursor which is again crypted by compilation. Is it a solution for it?

It seems like the program doesn't like figures being a child of uipanel:

??? Error using ==> set
There is no 'WindowButtonDownFcn' property in the 'uipanel' class.

Error in ==> dualcursor at 688
        set(get(axh,'Parent'),'WindowButtonDownFcn','','WindowButtonUpFcn','')

Error in ==> dualcursor at 220
        dualcursor('off',[],[],[],axh);

Error in ==> episodesPanel>slider_strip_Callback at 147
dualcursor([1 2], handles.panel.episodes.infoDisplay.axes_electrogram);
 
??? Error while evaluating uicontrol Callback

??? Error using ==> uicontextmenu
An object of class uicontextmenu, can not be a child of class uipanel.

Error in ==> dualcursor at 325
        cmenu = uicontextmenu('Parent',get(axh,'Parent'));

Error in ==> episodesPanel>slider_strip_Callback at 147
dualcursor([1 2], handles.panel.episodes.infoDisplay.axes_electrogram);

Is it possible to have this function be "modal". For instance, if I wanted to use this function in a script that asks the user to set the lower and upper bounds of interest using dualcursor, how do I have my code stop and wait for the user to slide the vertical bars to the appropriate locations? I guess I need a button added to the plot so that the program waits until the limits are set before the user hits the "submit" button?

If you have multiple plots in one figure how do you select which one to select?
Really nice work.

[Cédric Duchêne]

Thank you very much for this tool.

Is it possible to use this function on the horizontal axis ?
How do you think it should be difficult to add this ability to work in this case ? (Toogle mode vertical <--> horizontal)

Thank you again.

was gga do that my self but hey now i have it, thanks....

I would like to thank you very much for this precious work. And I need to ask you how we can have an additionnaly horizontal dual cursor at the same time in the same plot
Sincerly your's

[Francis]

Another vote for horizontal cursors.

[Preston]

Would it be possible to expand callback functionality so that I could call it within a GUI whenever a cursor was moved?
