Why Are My Excel Error Bars Only Horizontal?

Click For Summary

Discussion Overview

The discussion revolves around issues related to adding vertical and horizontal error bars in Excel graphs, specifically focusing on X-Y scatter graphs. Participants explore the inconsistencies in error bar options available for different graphs and seek solutions for managing data points with large error bars.

Discussion Character

  • Technical explanation
  • Debate/contested
  • Homework-related

Main Points Raised

  • One participant reports difficulty in adding vertical error bars to a specific graph, despite being able to do so on others, suggesting Excel may be 'deciding' the error bar options.
  • Another participant inquires if the graph types are consistent, hinting that different graph types might restrict error bar options.
  • Some participants confirm they have not encountered issues adding either type of error bars to X-Y scatter graphs, questioning the graph types being used.
  • A participant eventually manages to add vertical error bars after further attempts but raises a new concern about large error bars and how to delete specific data points without disrupting existing formulas.
  • Another participant suggests creating additional columns to manage data points selectively, preserving original data while allowing for modifications in the graph.
  • There is a proposed method using the "IF" function to conditionally display data based on error bar values, allowing for the exclusion of certain points from the graph.

Areas of Agreement / Disagreement

Participants express varying experiences with adding error bars, indicating a lack of consensus on the underlying issue. Some agree on the functionality of X-Y scatter graphs, while others report inconsistencies. The discussion on managing large error bars and data points also reflects differing approaches without a clear resolution.

Contextual Notes

Participants mention potential dependencies on graph types and data configurations, but specific limitations or assumptions regarding Excel's behavior remain unresolved.

I have a graph which I would like to add Y error bars to. When I click to add the error bars, it only allows me to add horizontal bars. This is very strange because the other graph I have, it allowed me to insert vertical bars.

Basically when I click on exactly the same menu to insert error bars, on one graph it takes me directly to vertical error bars and on the other graph it only allows me horizontal bars. I have for the last twenty mins been trying to get vertical bars on the menu that gives me horizontal bars. I don't know what else to try. I googled my problem but it just says click on 'More error bars options', but this is what I do by default.

It is if Excel is 'deciding' what error bars to give me.

Can anyone help?

EDIT: This is silly, now when I click on another graph I have created, I have vertical bars as my default... Vertical bars as default on two graphs, horizontal on the other - this makes no sense.

Many thanks.

Do you have a different type of diagram where you cannot add those error bars?
 
With X-Y (Scatter) graphs in Excel, I've never had trouble adding either horizontal or vertical error bars. What type of graphs are you using? Are they all the same type?

Yes, they are X Y scatter graphs. I click on the graph and then go the menu at the top of the page and click 'Error Bars'. Then I choose the option 'More options for Error bars'. On two of the three graphs (they are all the same, the only dissimilarity being the data) I can have vertical bars but on the third only horizontal. How did you manage to choose what ones you wanted?
 
I managed to get the vertical errors eventually by playing about with it some more. I have another question though. I have noticed that some of my error bars are very large in comparison to some of the others (as much as 30 times). I want to delete these data points from the graph. Is there a way to delete data points individually?

If not, I want to delete their entries in my table of data (I'll keep all raw data someplace else). How can I do this without messing things up (I have inserted formula so by deleting, it confuses Excel).
 
One way is to create additional columns that have the same data values, and in those columns delete the points you don't want included on the graph. Then you still preserve the original data, in case you change your mind about displaying it.

Or, you can use the "IF" function in the new column; if the error bar is greater than some cutoff value, then set the cell value to "" (i.e., a blank cell); otherwise the cell value is the data value from the original data column.

For example, if column D is to be the data that you want on the graph, then cell D3 could say

=IF(C3>E$1,"",B3)

where column B has the original data, column C has the error values, and cell E1 has the error bar cutoff value.
