GnuPlot 如何绘制具有不均匀网格数据的线框表面

我正在尝试绘制一组具有特定轴值的网格数据,其中 y 轴不均匀(例如 ... 150 180 195)。信不信由你,这是混凝土天花板的变形,我想用最少的石膏将其弄平...!网格值如下。 带有 x 和 y 轴数据的网格数据

我尝试了下面的宏,但结果却不尽如人意:

您需要关键字nonuniform

gnuplot> help matrix

(...) 

The second interpretation assumes a non-uniform grid with explicit x and y
 coordinates. The first row of input data contains the y coordinates; 
 the first column of input data contains the x coordinates.  For binary input
 data, the first element of the first row must contain the number of columns.
 This is the default for `binary matrix` input, but requires an additional
 keyword `nonuniform` for text input data.
 See `matrix nonuniform` for examples.
