Note that if you change the data in the plot, you'll need to repeat Step 4 to pass the new data into the function. Now the tooltip should display the extra data. #% Step 4: set the custom function as the updatefcn, and give it the extra. #% Step 2: get a handle to the datacursormode object for the figure
Matlab change cursor color code#
For example see my attached code where I changed the 0,0,0 to 1,1,1 (white). #% Step 1: create a custom data cursor function that takes. You need to modify the built-in ginput() function since they forgot to add this incredibly obvious and needed option of color. #% if the index is out of bounds (if/else statements don't work. #% Step 0: create a function to index into an array. Below I've implemented this using purely anonymous functions doing it within a function file would be slightly more straightforward.

This is a job for custom data cursor function. colorbar #% displays a colorbar legend showing the value-color mappingĮdit: The questioner wants to see exactly the data in the not-shown array, rather than just a color. You can change the colormap to suit your tastes. 5 When finished, you can close Settings if you like. Perhaps also reset the color to default when the user has moved their cursor outside. If you would like to enter a known RGB or HSV color value for your custom color instead, click/tap on More, select RGB or HSV, enter the custom color values, and click/tap on Done. Now in this mouseMove function you should have some sort of if state that tests if the cursor is moved into the button and if it is reference the button BackgroundColor propery to change it. 1 Open Settings, and click/tap on the Ease of Access icon. surf(X,Y,Z,V) #% 4th arg (V) is mapped onto the current colormap Pick a Custom Text Cursor Indicator Color in Settings. Using color as your 4th dimension is a possibility (whether it looks good to you is a matter of taste). Is there anyway to show the values for X,Y,V and Z without having to generate two separate graphs? I know that the way I have it set up is correct because if I make two plots, say: surf(X,Y,Z)Īnd then use the data cursor to go on the same point of X and Z for both graphs the values for V and Y are what they should be for that point (X,Z). If I use the data cursor, I can see values of X,Y,Z, but I would also like to know the values of V. Here is some test data to illustrate: X = linspace(1,5,5) I have used the surf function to plot X,Y,Z, but I also want to know the values of V, which I cannot currently ascertain. This may be easier to see the dependencies: X, V, Y(X,V), Z(X,Y(X,V)). I want to vary the independent variables X,V, to produce the dependent variables Y and Z.

I am having trouble figuring out how display 4 variables in my plot.
