I'm looking to put error bars on several line graphs. I know that I can adjust the error bars by line series, but can I specify the error bar ranges by data point? If so, how?

The graph labeled "Belief-Based 5-Class Model" is the one I'm working on
Excelchat Expert 17/08/2018 - 04:25
Belief-Based Subtypes 5-Class Model bar graph?
User 17/08/2018 - 04:25
Each data point in each of the line series on that graph has a different confidence interval that cannot be specified by a percentage. I need to add custom error bars to each of the data points...if this is possible
Excelchat Expert 17/08/2018 - 04:25
ok
Excelchat Expert 17/08/2018 - 04:25
go to design tab
Excelchat Expert 17/08/2018 - 04:26
under add elements -> error bar

So I see I can do that, but I then seem to only have the option of adding error bars based on line series and not based on data point
Excelchat Expert 17/08/2018 - 04:28
the error data is the same for all the bars
Excelchat Expert 17/08/2018 - 04:29
1 mean for a given series the same
Excelchat Expert 17/08/2018 - 04:29
so 1st select a series ...then under design ->add elements ->error bar
Excelchat Expert 17/08/2018 - 04:30
so you can keep repeating that for each of the series I/C ,P/U
Excelchat Expert 17/08/2018 - 04:30
and so on..
User 17/08/2018 - 04:30
Each of my data points in the series I specify come from three different scales, with different means and different confidence intervels. Can I specify the error bars by data point only?
Excelchat Expert 17/08/2018 - 04:32
no not for each data point. for a given series you can specify
User 17/08/2018 - 04:32
okay thanks, that's all I was looking for
