Standard deviation plot

I dears, is everything fine?

I need to add a standard deviation curve to my plot but cannot find much on internet. I have a dataset in .txt that contains 3 columns as shown below. The third column is the standard deviation of the second column values.


I plotted the first two columns but cannot find a good way to plot easely the third. I tried to preprocess the data in Excel but the result was not actually what I expected. Is there any command or argument I could use directly on gmt? I found on internet that there is a -E argument but it displays error bars and not a continuous line.

Thank you so much for your help :slight_smile:

You can use -i to select the columns of your dataset.

E.gā€¦ try adding -i0,2 to plot the first vs third column.
