title: Show datatips in a logarithmically scaled uiaxes
body: <p>I have encountered a problem using the new <code>uiaxes</code> object: after plotting my data, I can click on the data points then it will show a datatips displaying the X and Y data.
  When I change the scale of my X axis into a logarithmic one datatips won't display.</p>
  
  <p>I am using MATLAB 2019a.</p>
  
  <p>Here is a sample code :</p>
  
  <pre><code>h = uiaxes;
  h.XScale = 'log';
  a = plot( 1 : 10 );
  </code></pre>
  
  <p>By changing the scale back to linear, the datatips would display correctly again.</p>
  
  <p>I also tried the below command in order to enable the datatips, it works but I have a ton of warnings on my command window saying an error occurred in the <code>WindowMouseMotion</code> Callback.</p>
  
  <pre><code>cursorMode = datacursormode(h.Parent);
  cursorMode.Enable = 'on'
  </code></pre>
