I have a macro that plots pairs of columns and wish to change the symbol types for each curve to be the curve number. For example, if I add plots from worksheet JvsV to a layer as in the following:
loop(ii, 1, ipasses){
lay -i202 %(JvsV, 2*ii);};
In this case voltage columns are V1, V2, ..., and current density columns are J1, J2, ... I would like to also change the plot symbol to be equal to the number ii. I can change to color number ii with no problem using
set JvsV_J$(ii) -cl ii;
and tried using
set BvsV_J$(ii) -k 11;
but this sets the symbols to equal the data point number (symbol for first data point is 1, second data point is 2, ..., Nth data point is N). I figured out how to manually set the symbol to a given character using the plot properties, but I want to do this in a script. Is there a labtalk command to set the symbol for each plot to be the curve number? |

Your last expression should work unless the set command is interpreting the dataset name incorrectly. You might try this variation for kicks...
%A=BvsV_J$(ii);
set %A -k ii;

That doesn't work. If I use
%A = JvsV_J$(ii);
and then
set %A -k 11;
each curve has symbols 1,2,3,4,5,etc. If I use
set %A -k 12;
each curve has symbols A,B,C,D, (A for data point 1 in the column, B for data point 2 in the column, ...) etc., and if I use
set %A -k 13;
then each curve has symbols a,b,c,d,...
I can use the lower numbers and variations like
set %A -k 1;
to get square symbols. I can also manually set the curve symbol to be a fixed number using the plot details box, but I am writing a macro that plots something like curve tracer data, and there are many curves for one measurement (and multiple measurements to look at - not on the same plot - too messy). |

So you want a to label each point in a curve with the curve number? You've found the ways to get incremental numbers and letters, but it appears the it is only possible to get individual alpha or numeric symbols for each dataset is through the Plot/Details Dialog.
Alternately you could try:
A) Creating BMP graphics of 24 letters/numbers and using these.
B) Use "set DatasetName -k value", where value = 100 + number-of-columns-to-the-right. For example, to base the symbol shape on a dataset located two columns to the right of the data plot's Y dataset in the worksheet, use value = 102. (Note: There is a limit of four columns to the right.)
I don't think this would be a tough thing for Origin to add to the labtalk set -k shape# command since there is lots of room between 20 and 56. I'm sure I would find this feature worthwhile.

Either that, or they could just use something like a "-kn char#" switch to the set command that uses the character number in the set of characters in the Plot/Details dialog. Then there are lots of characters to choose from, and I might use letters for curve numbers >= 10. What I really want is a plot label that is the curve number, though, and that would require a string instead of just a single character.
I tried the 100 plus number of columns to the right method. As far as I can tell, the entries in the column to the right have to be indices into the allowed symbol type numbers used for the "set DataSet -k value" command (value=1 for square, 2 for circle, etc.).
Thanks for all the help. I don't really want to deal with bitmaps, so I think for now I will just use symbols and a legend to decode curve number. |

What about using Plot Details to set the symbol to 1 and then making sure the datasets are grouped so that they increment. This would only be good up to 9 datasets per layer. You could then save the template.

That is a good idea, but we are plotting 20 traces at a time. After some discussions with various users of the macro in my group, we came up with a way to visualize the data in bands coded first by color and then by symbol type. It turns out visualizing by bands of color provides a better idea of what happens during the experiment than plotting curve trace number.
Cheers! |

you can easily acomplish this with:
SET %C -ka 49; // 48 + nCurve
labtalk script
Thanks,
Roman. |

It seems Roman's method only works for values of ncurve up to 9. After that you get other symbols (not numbers). It is great to know how to do this, though.
Thank you for the help! |
