There are different ways you could do this depending on your specific use case.
If the graphs you want to make are all the same except you have a different set of inputs, one possiblity would be to set up one graph and use a Text Menu with a mask, such that when you change the selection in the Text Menu the data in the graph will update.
Then on the Text Menu, you can output every version of the table at once using the batch output option, which is described here:

This requires you to have all the data in one table. There are two ways automate this process with multiple files.
One way is to drag and drop all the files at once onto the Data List side panel. That will create a group for each file where the file name is the group name. Then place all of these group in one overall group. Once that is done, use the Append subgroups option on the overall group as described here:

Another way is to use the Import Special to create a parser and select all the files as input. Before you import you can check a box to include the file name as a column. Unless your data is rather complicated, I would recommand the Appends subgroups method first, rather than the Import Special, which may take more time to set up.
Does this help?
