    <p>Your colorbars are children of the figure, not of your subplot axes (colorbars are themselves axes). Try</p> <pre><code>hc = get(hf, 'children') </code></pre> <p>to get a list of all children of the figure, where <code>hf</code> is the figure handle. I'm not sure how you would which element of <code>hc</code> is equal to your <code>Hc</code>, i.e. which is the <code>first</code> colorbar.</p> <p><strong>Edit</strong>:</p> <p><strong>If you need to use an object's handle later on, it is best to assign it to a variable when it is created and to use that variable throughout.</strong></p> <p>However, if you don't want to do this (although I strongly recommend that you do) I can think of two things you can do. They are not particularly elegant and are definitely more work that just assigning your object handle to a variable.</p> <p>If you know the order in which the axes were created then you are in luck: in the list if children, the first child created is the <em>last</em> element in the list and the last child created is the <em>first</em>. For example,</p> <pre><code>hf = figure; ha1 = subplot(1,2,1); image(rand(5,5)); hc1 = colorbar; ha2 = subplot(1,2,2); image(rand(5,5)); hc2 = colorbar; hcs = get(hf, 'children') hcs = 206.0016 204.0011 176.0016 174.0011 [hc2, ha2, hc1, ha1]' ans = 206.0016 204.0011 176.0016 174.0011 </code></pre> <p>Since you want the first colorbar, which was the second child created, you can then use</p> <pre><code>hc(end-2) </code></pre> <p>Alternatively, when creating the colorbar which you want to refer to in the future, set it's <code>tag</code> property. In the above example, replace the line</p> <pre><code>hc1 = colorbar; </code></pre> <p>with</p> <pre><code>hc1 = colorbar('tag', 'myID'); </code></pre> <p>You can then get the handle to this object later with</p> <pre><code>findobj(hf, 'type', 'axes', 'tag', 'myID') </code></pre>

    1. COThank you. Yes, it is the children of the figure. But if there are more than one colorbar in the figure, how to determine which is the one for the axes?

    2. CO@Xun I have edited my answer to offer some solutions. However, I reiterate that it is best to store the handle to an object when you create it if you are going to use it later on, rather than try to find the handle at a later time.

    3. COThank you for your answer. It's helpful. But I found another solution, which can found the colorbar of an anonymous axes handle.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
