Hi!
Well my question is a litle complicated.
My code open a worksheet, make a graph from x e the first y and get 2 points of the graph.
The problems is i need to rename the column where the 2 points had been kept.I just created the dataset that contains the 2 points, but not open.If the dataset will be opened, does not show all the points to the graph.The line "layer -a" does work!!! But, if i put the command in the lab talk console, it works perfectly!
For more details see the code below:
win -a %h;
worksheet -s 2 0 2 0;
worksheet -p 200 Origin;
layer -a;
create line -d 2;
edit line;
work -n 2 B;
win -a %h;
GetPts -n line 2;
Please help me and forgive my English! |

I am not sure about if I get you wrong. It seems that your code is trying to do the following:
1) Create a plot from an existing worksheet.
2) Create a dataset and rename its second column.
3) Use datareader to read two points on the graph and save their XY values in the dataset.
Please correct me if there is anything wrong. It will help us understanding your question.

Please help me with the following:
1) Do you want to rename the second column of the worksheet Line?
2) I am not quite sure about what you want with rescaling? Do you want to rescale the graph according to the two points you select with the data reader? That means from

I'm not sure why you use create -n to create the worksheet. You can either use create -wd to create the columns but not the worksheet or win -t Data to create a normal worksheet from the default wks template whose column names are already A and B. If you do the latter first save the graph window name and reactivate the graph before executing the GetNPts command.
Also win -a %h activates the already active window and is therefore redundant. And layer -a is unnecessary after wo -p because the latter command performs the scaling.
wo -s 2 0 2 0;
wo -p 200 Origin;
create Line -wd 2 A B;
GetPts -n Line 2;

Yes...when i create a worksheet whith columns name A and B, and the function getpts get the points, they are stored in another column Y,not in B.
The rescaling problem appears when i open the worksheet line. my plotted graph doest showed with the normal y values and i cant get the points that i need.
I hope to have been clearly!
Thanks for the helping!

Both the create -d and GetPts -n commands take Y dataset names, not worksheet names, as arguments. This works...
wo -s 2 0 2 0;
wo -p 200 Origin;
create Line_B -d 2;
GetPts -n Line_B 2;
...Note that adding layer -a after GetPts will not work because rescaling will occur before any points are selected. To rescale after each point selection you need to define and use the PointProc macro as shown below.
wo -s 2 0 2 0;
wo -p 200 Origin;
create Line_B -d 2;
layer -i201 Line_B; // add to layer as scatter
getpts.max=2; // select 2 pts
def pointproc {
Line_A[getpts.count]=x;
Line_B[getpts.count]=y;
layer -a; // rescale
if(getpts.count==getpts.max) dotool 0; // quit
};
dotool 2; // open screen reader
