Origin Ver. and Service Release (Select Help-->About Origin): 7.5
Operating System: win2000
hello everyone, I am quite new to the forum and also to the writing a script. I need to plot multiple x-y line graphs from different columns. Lets say I have 4 columns and I want to plot column 1 as x, 2 as y for the first graph, and 3 as x, 4 as y for the second graph.
For instance:
plotxy iy:=(1,2) plot:=200;
and
plotxy iy:=(3,4) plot:=200;
at the same time. But how do I get these two commands working together ? When I write them both, it plots the first graph, and than says Command Error! not plotting the second one.
When I use plotxy iy:=((1,2),(3,4)) plot:=200; It plots everything on the same graph. But I need separate graphs.
(1,2) and (3,4) are only example btw. There are more columns on the original problem, but I think I can manage it after I can find out how to plot these two on different graphs.
Thanks in advance!!

Hello,
you can use for statement to plot multiple graphs.
for(int i=1;i<5;i=i+2)
{
win -a Book1; // active the data book
plotxy iy:=($(i),$(i+1)) plot:=200; // plot the XY data
}
Best regards,

Hello, thanks for the reply. But what happens when the problem gets complicated? For example when I need to plot (2,5),(1,3),(6,4) and so on (without a pattern like (i,i+1) ).. Is there a way to define the columns only by entering the column number ?

Hello,
you can try to make a macro
define plot{ //define macro first
win -a Book1; // active the data book;
getn
(X) x
(Y) y; // use dialog for input
plotxy iy:=($(x),$(y)); // plot XY
};
//------------------------------------//
plot //Executing the macro each time for one plot

Hello, thanks again for the answer. I tried this way but is worked only for the first graph, when I tried to execute it second time, it said command error! unless I delete the first graph. So back to the point, I need 4 Graphs, to be specific from the columns (1,6) , (2,4) , (6,7) , (8,7) for every single file and I don't want to select plot, then select every time the right columns from that table, I just want to write a command, and voila, there are the 4 graphs each time I need. But I can't execute the script for multiple graphs in one script, or without deleting the graphs, right ?

Hi, Alpy
So just activate the workbook you want to operate on, and run the following script:
// Start
string PlotIndex$ = "(1,6)|(2,4)|(6,7)|(8,7)";
string DataBook$ = %H; // Remember the data workbook's name
for (ii = 1; ii <= PlotIndex.GetNumTokens("|"); ii++) {
window -a %(DataBook$);
string CurrentPlot$ = PlotIndex.GetToken(ii,"|")$;
plotxy iy:=%(CurrentPlot$);
}
// End
If you want to change the column for plotting, simply modify the PlotIndex$ variable.

Hey,
I had the very same problem and this conversation has really helped.
Thank you all very much.
But, is there a way to give different names for each graph and apply themes separately to each of them?
Could anyone please help me with the same?

Hi,
Add two variables in the example above:
string PlotIndex$ = "(1,2)|(3,4)";
string DataBook$ = %H; // Remember the data workbook's name
string GraphName$ = "Test1|Test2";
string GraphTemplate$ = "Polar|glWater3D";
for (ii = 1; ii <= PlotIndex.GetNumTokens("|"); ii++)
{
window -a %(DataBook$);
string CurrentPlot$ = PlotIndex.GetToken(ii,"|")$;
string CurrentName$ = GraphName.GetToken(ii,"|")$;
string CurrentTemplate$ = GraphTemplate.GetToken(ii,"|")$;
plotxy iy:=%(CurrentPlot$) ogl:=[<new template:=%(CurrentTemplate$) name:=%(CurrentName$)>];
}
More info about plotxy X-Function please refer to:
