Note variation in the scale of the y-axis among plots.
All data sets have nonzero intercepts of the regression lines with the y-axis .
Start to draw the slope at the left-hand vertical line of grid, which is the y-axis .
The x-axis shows the population in millions whilst the y-axis shows different age ranges.
Consecutive locations outlining an ' impact corridor ' are linked along the y-axis .
Note the differences in the scale of the y-axis .
Significant differences are for the photosynthetic rates on the y-axis .
For graphical purposes, a log scale is used for the y-axis .
The fitted lines are for the regression of the square root of the y-axis variable on log shoot dry weight.
For graphical purposes, the cubic function in (a) is not extended below the y-axis .
