smartsheet graphs

data, such as mesh, can be implemented using the PLOT3 function if only some data points in the mesh image are drawn. For example, the next section of code can be used to draw points, and the function of the connection:x0 =0; Y0 =0; Z0 =0;p lot3 (x0,y0,z0,' *k ',' LineWidth ',2,' Markersize ',Ten);p lot3 (indexcol,indexrow,z0,' *k ',' LineWidth ',2,' Markersize ',Ten);p lot3 (Indexcol,indexrow,maxscore,' *k ',' LineWidth ',2,' Markersize ',Ten); XX2 (1) = x0; XX2 (2) = Indexcol;yy2 (1) = y0; Yy
