<div class="markdown_content"><p>Pure axial projection of a 3D plot are treated as 2D plots, complete with the normal border drawn around it. You are seeing this border, just as you would if you had created the plot with <code>plot</code> rather than <code>splot</code>. You could turn it off with <code>unset border</code>, but then the partial bounding box lines would also not be drawn in the general 3D view angle case.</p></div>

<div class="markdown_content"><p>When doing a 3d plot using the<code>splot</code> command and rotating the plot to a view along the x-axis, the plot has a black box around it, if the view is exactly 90,0. The black box disappears if the view is 90,360 however.</p> <p>Version of gnuplot: 6.0.2 (Present sice 6.0.0), qt terminal (also happens in x11 terminal)<br/> OS: Linux Mint 22.1, Linux Kernel 6.8.0-57-generic<br/> Steps to reproduce:<br/> - Open gnuplot in a terminal<br/> - Define any function dependent on 2 variables, e.g. <code>f(x,y)=x*x+y</code><br/> - <code>set view 90,0</code><br/> - <code>splot f(x,y)</code><br/> - The black box should now appear<br/> - <code>set view 90,360</code><br/> - <code>replot</code><br/> - The black box should now have disappeared</p></div>
