Hi Martin,
When you draw data using the "Draw Data" tool, a new dataset is created - Origin creates a hidden worksheet (such as Draw1) that contains the xy data of the points. Use Project Explorer to find the worksheet and to bring it up from hidden state.
When you use the Free Hand Draw tool to draw a curve on the graph, a dataset is not created. The drawing is an object on the graph layer. Say your object name is Polyline. Then you can access the x,y coordinates of the points in your object by typing
polyline.x1=
polyline.y3=
etc in your script window. You could write LabTalk code to get all the values and put them into say columns of a worksheet, thereby creating a dataset.
As for function plots, you can right-click on the function plot, or go to Plot Details and ask for a function plot copy. You can then get to the worksheet of the copy by right-clicking on the curve in the newly created graph.
