How can I include error bars in a graph?
The situation is this: I have a data set and choose a function (eg linear) to represent them.
How do I put an error bar on the graph to represent the difference (positive or negative) between the estimated and the theoretical value?
I want that the error bar is related to data and the function I chose to represent them.
Thank you |

You are using Origin 8.0. To do statistics on rows, you should select contiguous columns. That is, in this case, select column 2, 3, 4, or 2, 3, or 3, 4. Selecting column 2, 4 will failed.
In Origin 8.1 or later versions, we have fixed this problem.
Thanks

I had the same problem recently. But I found a solution. There are at least two ways of highlighting columns. When you are using the first way you click on required columns in turn with pressed Ctrl. And when you are using the second way you slide by cursor of mouse on required columns with pressed left mouse button. The result of highlighting using first or second way is the same, but after using first way you have a problem "Non contiguous ranges is not supported in this tool" and after using second way Origin works correctly. So use second way described above.
I don't know the reason of this problem. Maybe it is bug of program. |

I followed the steps in the tutorial, as shown below. But I made a mistake, but can not figure out where. Can you help?

To simplify the addition of Residuals as Error Bars, you should make sure you use 'Same as Input Data' as the X Data Type. Click the green Operation Lock and choose 'Change Parameters'. Set the X Data Type in the Fitted Curves Plot section.
Double click the Layer1 icon in the upper left of your graph to open Plot Setup. Expand the dialog to show all three panels and choose Worksheets in Folder and select the FitLinearCurve# sheet.
In the Plot Type panel, select the Independent Variable as the X, the Linear Fit as the Y and the Residual as the yEr. Click Add and click OK.

Hi:
You should first have column of data as the Value of Error Bars. Such as in This Tutorial.
Thanks
