Hello!
I have the following import filter which imports and plots and x, z graph: %A = page.info.system.import.filename$; //Get the filename %B = %[%A, '.']; plotxy iy:=((1,2)) plot:=200 ogl:=[<new template:= XRR_Templat name:= %A>]; // Plot data, rename the graph window
What I want to achieve is that x,y are importet and then log(y) is automatically calculated and plottet against x. Any ideas how to do that?
After file imported, you need to add a column, and put the value of log (y) in the new column, then plot the graph. To achieve it, you can add a few lines of script in your import filter:
nn = wks.nCols; //Get the number of columns
wks.nCols = nn + 1; // Add a column in worksheet
col($(nn+1)) = log(col(2)); // Calculate the log value of column B
plotxy iy:=(1,$(nn+1)); //Plot x vs log(y)
Import x, y; calculate log(y) and plot
