[proFit-list] How can we disconnect two data points?

[pro Fit Support]

Dear Riki

You can issue two Plot commands, one for the set of data before the gap, and the other for the set of data after the gap.

Alternatively, if you have lots of gaps and/or if you have to do it often, you could write a script. It would basically look something like this:

program MyPlotCommand;

const
	xCol = 1;
	yCol = 2;

var r: integer;
	gap: Boolean;
	x, y: real;

begin
	CreateNewGraph(0, 10, 0, 10, 0, 0);
	gap := true;
	OpenCurve(name 'the data');
	for r := 1 to NrRows do
	begin
		if DataOk(r, xCol) and DataOK(r, yCol) then
		begin
			x := data[r, xCol];
			y := data[r, yCol];
			if gap then
				MoveTo(x, y)
			else
				LineTo(x, y);
			gap := false;
		end
		else
			gap := true;
	end;
	CloseCurve;
end;

This script runs through the data and issues MoveTo and LineTo commands into a graph in order to create a curve with gaps in it.


Best regards
