Points on the line chart show error bars

1.When I draw a line chart (such as the picture below), how to make this line chart with error bars.

 

2.How to make this two-line alignment comparison effect, as shown in the figure below.

We just added an article to explain How to add Error Bars.

To add lines at specific locations you can use the Lines command and specify the extent of the line.

Does this help?

It means that I first calculate the error value on the line chart and then add it to the line, right?

The Plot command does not perform any calculation, only draws data as specified in the table, so yes, you must have a column with the error value calculated.

If you need to calculate use the Pivot command to group the data and calculate the means and error.  Then the Pivot command can output these values to the table for plotting.

There are several examples files that demonstrate.  Try searching “Pivot mean SEM”.

I have the confidence interval calculated (low and upper values). How can I use plot to fill the space between the main line and the confidence intervals with a different color while keeping the main line visible?

Do you mean something like this?

The envelope here is drawn by using the upper and lower values in the data table.  This is done with one Plot command, in which you have to specify the column that the fill goes between, in this case the lower.

We just added a new example file that has this graph and a couple of other examples.

Also make sure the line you want to show over is the last command in the list.  Each command is drawn in order.

Does this help?
