title: gnuplot: 3d scatter plot with circles
body: <p>I am trying to do a 3d plot, where I want each point to be with my choice of color/shape/shade. The fact is that I want to use the colour palettes from <a href="https://github.com/Gnuplotting/gnuplot-colorbrewer" rel="nofollow noreferrer">here</a>. </p>
  
  <p>Lets say my data is like this --</p>
  
  <pre><code>0   0   0
  0   0   1
  0   1   0
  0   1   1
  1   0   0
  1   0   1
  1   1   0
  1   1   1
  </code></pre>
  
  <p>and my gnuplot command looks like this --</p>
  
  <pre><code>set style fill transparent solid 0.75 noborder
  set style circle radius screen 0.01
  splot "data.out" with circles linecolor rgb "blue"
  </code></pre>
  
  <p>and I am getting this plot --</p>
  
  <p><a href="https://i.stack.imgur.com/1SIls.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/1SIls.jpg" alt="enter image description here"></a></p>
  
  <p>as you can see, there is no circle, every point is <code>+</code>.</p>
  
  <p>How do I draw with circles ?</p>
