Gnuplot cblabel not appearing
<p>I am trying to plot a function of two variables represented in tabular form. I would like to label my color bar while representing this as a heatmap. No matter how much I rescale, no luck, and I don't even see the colorbar label appearing. Here is my gnuplot script:</p>

<pre><code>set title "Flux in core vs radius and height"
set view map
set cblabel "Neutron flux (cm^-2 s^-1)"
set xlabel "Radius (cm)"
set ylabel "Axial distance from center (cm)"
splot "flux.out" using 1:2:3 with image
</code></pre>

<p>And the result looks like this, lacking a colorbar label:</p>
