For this we need to enter at the Scilab console the following instructions: ->xgrid ->xlabel ('x') ->ylabel ('sin (x), cos (x)') ->title ('Plot of sin (x) and cos (x)') ->legend ('sin (x)','cos (x)',3) The grid is displayed with the function xgrid (). If the object is not listed in the Children property of the parent, thenįunctions that obtain object handles by searching the object hierarchy or querying To have a complete plot we need to add a grid, labels for both axes, a title and a legend. This optionīlocks access to the object at the command line, but permits This option is useful for preventing unintendedįrom within callbacks or functions invoked by callbacks, but notįrom within functions invoked from the command line. Otherwise, use the gcbo function to access the object.Īll times. If you specify this property as a function handle or cell array, you can access the object that is being created using the first argument of the callback function. Setting the CreateFcn property on an existing component has no effect. If you do not specify the CreateFcn property, then MATLAB executes a default creation function. MATLAB initializes all property values before executing the CreateFcn callback. This property specifies a callback function to execute when MATLAB creates the object. MATLAB evaluates this expression in the base workspace.įor more information about specifying a callback as a function handle, cell array, or character vector, see Create Callbacks for Graphics Objects. Subsequent elements in the cell array are the arguments to pass to the callback function.Ĭharacter vector containing a valid MATLAB expression (not recommended).
