Hello,
I have different datasets in one layer, but with different x-values. For further jobs, I need to calculate the mean y-value of every x-value. Is there a possibility to get all x-values together in one column, to calculate the associated mean y-values afterwards?
Thanks Alex |

Hi Alex,
The following script interpolates all datasets over the same X values and performs Statistics on Rows on the results...
nn=100; // number of X values (adjust to suit)
xx1=layer.x.From; // first X value
xx2=layer.x.To; // last X value
xxi=(xx2-xx1)/(nn-1); // X increment
%Z="";
lay -c;
win -t D;
%W=%H;
col(1)=data(xx1,xx2,xxi);
wo -a count-1;
loop(i,1,count) {wcol(i+1)=%[%Z,#i](col(1))};
wo -s 2 0 wks.ncols 0; // select all Y columns
run.section(WKS,DescStats,1); // statistics on rows
wks.col1.name$=A; // rename column 1
col(1)=%(%W,1);

get all x-values of the layer
