spearman's is a value which represents the strength of correlation between two sets of data.

do you mean illustrating your data with a line of regression, which is an accurate line of best fit, so there is equal distance between each piece of data from the line?

if it's regression you mean, there's more info on how to plot it here:

Plot out your results on a scatterplot. If you found a significant relationship (either positive or negative) then draw the line of best fit, as described above. If you found no significant relationship (r = 0) then no line is needed as it would mean nothing.
