title: How to make a nice 3D plot in R for time series spectral data
body: <p>I am trying to do a nice 3D plot using time series UV-Vis spectral data, like the first 3D graph below.</p>
  <p><img src="https://i.stack.imgur.com/FDUZZ.png" alt="Example 3D graph" /></p>
  <p>I used dput() function to show my data as below.</p>
  <pre><code>dput(head(Data)) 
  </code></pre>
  <p>and get:</p>
