MATLAB: How to enable zooming on custom GUIs that have multiple axes

customenableguisMATLABzoom

I have a custom GUI with multiple axes. How do I perform zooming operation on the axes like on any standard figure?

Best Answer

 You can use either of the following solutions to enable zooming operation in the custom GUI:

1. You can create the toolbar that includes zooming functionality and control its visibility property to enable the toolbar in your custom GUI. Please refer to the following links for more information on creating the toolbar on figures in MATLAB, and to control the appearance of the toolbar, respectively:

https://www.mathworks.com/help/matlab/ref/matlab.ui.container.toolbar-properties.html

For example, consider a figure that does not have a toolbar to perform zooming, as follows:

>> f = figure('ToolBar','none')

You can set the "toolbar" property of the figure to enable the toolbar in this figure. You can do so, by executing the following command in the Command Window:

>> set(f,'toolbar','figure');

2. You can turn on interactive zooming by using the "zoom" function. Please refer to the following link for more information on using the zoom function:

MATLAB: How to ensure that zoom is on by default when I open a figure

In order to do this, consider using the 'CreateFcn' callback for a figure. This callback is designed to execute when a figure is created or opened. Using the 'CreateFcn' figure callback to set the zoom option to be on will allow the figure to be zoomable when it opens.

For example, refer to the following lines of code:

>> f=figure;     % Create a figure
>> plot(1:10);  % Create a plot on the figure
>> zoom on     % Set the zoom option to be 'on'
>> f.CreateFcn='zoom on';  % Modify the 'CreateFcn' figure callback so that the zoom is turned on when the figure is created
>> savefig('Test1')  % Save the figure to a file called 'Test1.fig'

After executing the code and opening the 'Test1.fig' file in MATLAB, the zoom option should be set to 'on'. For details of each line of code above, refer to the comment at the end of each line. For more information about figure callbacks and properties, please refer to the following link:

MATLAB: How to use custom date labels for the x-axis in MATLAB plots

It is more convenient to format the tick labels using the "XTick", "XTickLabelMode" and "XTickLabel" properties of the axis object (vs. using "datetick" function):

>> figure
>> box on
>>
>> % Start, end and number of ticks...
>> startDate = 7.3457e+05;
>> endDate = 7.3458e+05;
>> numbertick = ceil(endDate - startDate);
>>
>> % Plot them
>> xData = linspace(startDate, endDate, numbertick);
>> plot(xData,ones(size(xData)));
>>
>> %%Modify the axes properties
>> set(gca, 'XTick',xData)
>> set(gca, 'TickDir', 'out');
>> set(gca, 'XTickLabelMode', 'auto');
>>
>> % Modifying the labels
>> labels = get(gca, 'XTickLabel');
>>
>> for i = 1:length(labels)
>>     if i == 1 || i == ceil(length(labels)/2) || i == length(labels)
>>         labels{i} = datestr(xData(i), 'mm/dd');
>>     else
>>         labels{i} = '';
>>     end
>> end
>>
>> set(gca, 'XTickLabel', labels)
