我对该选项有疑问shader=interp。如果没有该shader=interp选项，我得到的是按行排序数据的平滑 3D 图，如下图所示：
现在我想用该shader=interp选项来平滑我的情节，情节如下所示：
有人能解释一下这种行为并给出解决方案吗？以下是代码和数据：
\begin{figure}[htbp]
\centering
\begin{tikzpicture}
\begin{axis}[unbounded coords=jump, xlabel={Höhe [ft]},ylabel={$V_{TAS}$ [kt]}, zlabel={Anstellwinkel $\alpha$}, width=\textwidth, x dir=reverse, y dir=reverse, grid=minor, x tick label style={/pgf/number format/fixed}, y tick label style={/pgf/number format/fixed}, scaled x ticks = false, scaled y ticks = false, colorbar]
\addplot3[surf, mesh/rows=9, mesh/ordering=colwise, shader=interp] file {Test_Data.dat};
\end{axis}
\end{tikzpicture}
\label{plot:alpha_matrix}
\end{figure}
