An object can become the current object as a result of pressing the space bar to invoke a callback in a dialog when a uicontrol in that dialog has focus (usually the result of using the Tab key to change focus). By default, MATLAB ® measures the values in units normalized to the container. To change the units, set the Units property. The left and bottom elements define the distance from the lower left corner of the container (typically a figure, panel, or tab) to the lower left corner of the position boundary. ylim (limits) sets the y -axis limits for the current axes or chart. Specify limits as a two-element vector of the form [ymin ymax], where ymax is greater than ymin. example. ylim (limitmethod) specifies the limit method MATLAB ® uses for automatic limit selection. Specify the limit method as "tickaligned", "tight", or "padded".F = getframe (fig) captures the figure identified by fig.

I have generated the …Description. xscale (scale) sets the scale of the x -axis to be linear or logarithmic in the current axes. Specify scale as "linear" or "log". You can also omit the parentheses and quotation marks when using this syntax. For example, xscale log is equivalent to xscale ("log"). xscale (ax, ___) sets the scale for the specified axes object. The reason is that, in most contexts, MATLAB defaults to using the gcf or gca functions to get the target object for an operation. But these functions depend on the HandleVisibility property of the parent figure being 'on' , and the HandleVisibility property of App Designer figures is set to 'off' by default.Find all objects in the current figure and any descendants that are up to two levels lower in the graphics object hierarchy. h2 = findobj (gcf, '-depth' ,2) h2 = 5x1 graphics array: Figure (1) Axes Axes Line Line. Restrict the search to the …set(get(gca, 'YLabel'), 'visible', 'on') This should get you close to what you are looking for.

A couple of days ago, a reader of Matlab’s official Desktop blog asked whether it is possible to determine if an axes has been zoomed or not. I have encountered this question myself some time ago, when I tried to customize a radar plot: The grid in radar plots does not automatically re-draw when ...The axes might select new axis tick mark locations as well. f = gcf; f.Position (3) = f.Position (3) * 0.67; Reshaping the axes to fit into the figure window can change the aspect ratio of the graph. MATLAB fits the axes to fill the position rectangle and in the process can distort the shape.Use manual mode to maintain the current x-axis limits when you add more plots to the axes. First, plot a line. x = linspace (0,10); y = sin (x); plot (x,y); Set the x -axis limits mode to manual so that the limits do not change. Use hold on to add a second plot to the axes. xlim manual hold on plot (2*x,2*y) hold off.xticks (ticks) sets the x -axis tick values, which are the locations along the x -axis where the tick marks appear. Specify ticks as a vector of increasing values; for example, [0 2 4 6] . This command affects the current axes. xt = xticks returns the current x -axis tick values as a vector. example. xticks ('auto') sets an automatic mode ... xl = xticklabels returns the x -axis tick labels for the current axes. example. xticklabels ('auto') sets an automatic mode, enabling the axes to determine the x -axis tick labels. Use this option if you set the labels and then want to set them back to the default values. xticklabels ('manual') sets a manual mode, freezing the x -axis tick ...The MATLAB ® software stores the handle of the current object in the figure's CurrentObject property. An object can become the current object as a result of pressing the space bar to invoke a callback in a dialog when a uicontrol in that dialog has focus (usually the result of using the Tab key to change focus). I try to do changing the origen of axis to the center of the plot. I have written in matlab: Theme. Copy. ax = gca; ax.XAxisLocation = 'origin'; ax.YAxisLocation = 'origin'; Matlab say: While setting the 'XAxisLocation' property of Axes: 'origin' is not a valid value. Use one of these values: 'bottom' | 'top'.Set axes properties after plotting since some plotting functions reset axes properties. To access the current axes or chart without forcing the creation of Cartesian axes, use dot notation to query the figure CurrentAxes property.
