First create new channels that have the data that you want displayed, in this case slope and intercept. Then create a table to be displayed on the graph so that it has two columns then choose column 1 to be 'expression' and pick the channel that you want to display. Choose column 2 to be 'channel' and again pick out the data that you want displayed. In this way you can use this in an autosequence so that the table will display the new slope and intercept for each new set of data.
