Hello!

So my data consists of four measurements which I have to merge and calculate the Y standard deviation. That goes without problem. Now for approximately 1600 data points I also get 1600 different standard deviations. I want to add some error bars but I can only add all 1600 ones and that of course looks silly. Is there a way to tell the programme to only pick an error bar every 200 data points or a similar function?

Thank you very much!

Hi toraneko,

Then, you need to create an extra error column with skipping missing values, that is: 

1) Insert a column, and designate as YEr. (e.g., when you have A(X)B(Y)C(YEr) columns, 
then make A(X)B(Y)D(Yer)[empty]C(YEr) columns.) 

2) Using Set Column Values tool, fill skipping missing values(=1/0) with a formula like: 
  mod(i,200)==0?col(C):1/0

3) Plot the data with your new error column.

Hello!

We even have two cats :)
But unfortunately I only have origin 8, is there a way to do the same thing there?

Thank you!

Hi toraneko, (<-- do you have a cat? :-) )

If your Origin is of a recent version (at least 8.5), once you plat the data with all
error bars, you can eliminate by setting N bars, or by skipping N bars from the
Plot Details dialog. To do so, choose the error bar dataset from the left panel,
and in Error Bar tab, you can set the option of "At which datapoints to draw".
