Why is errorbar plotting returning error when all inputs are doubles?
显示 更早的评论
Hello,
I am attempting to plot a years worth of data in hour incriments, with the time on the x axis and the units of my data on y. I have a value of error for each hour point, and the code for the data plot is
errorbar(datetime(data(:,1:6)),data(:,7), data(:,8))
datetick('x','mmm')
Where the data looks like this
And it gives the error
Error using errorbar (line 76)
Input arguments must be numeric or objects which can be converted to double.
I am very confused as the data is in a double, and it has no problem plotting without the errorbars if I just use the code plot(datetime(data(:,1:6)),data(:,7)).
What can I do to make this plot with the error bars? I have tried assigning them as x, y, err outside of the function, but that also didn't work.
Thank you for any help.

Can you upload the data, instead of an image of the data? We can't work with an image.

Hi,
You have overlooked the conversion into date.
Here is the corrected solution code:
clc; clearvars
D=xlsread('datafile.xlsx');
Date1=datenum(D(:,1:6));
errorbar(Date1,D(:,7), D(:,8))
datetick('x','mmm')
Probably, you may need to compute the averages and then error plot. Or go over by monthly.
As is, the plot contains way too many data that is faily difficult to see the process dynamics.
Good luck.
