The rule for a good graph can be found that the scales in for the two axes are
-  x-axis    3 values ​​/ box
-  y-axis   0.75 values ​​/ box
Graphical representation is the best method to visualize a set of data and understand the relationship between them.
A good graph must ensure that the data occupies the largest possible part of the sheet and the resolution is such that errors can be visualized.
The way to make a good graph must comply with:
- The best range where the values ​​occupy the maximum of paper. Let's use the relation
          Range = [tex]\frac{Value_{final} - Value_{initial} }{boxes}[/tex]
Where Value area the experimetla value, boxes are the division grid.
- If the value is fractional it must be close to the following value, for example the range is 0.95 it must be close to 1
- If the data is very large or small use scientific notation
- If the model contemplates the zero crossing, it should be included in the graph
In this case the paper divisions are 20 boxes on each axis, let's find the range
x-axis
     Rₓ = [tex]\frac{60-0}{20}[/tex]60-0 / 20
     Rₓ = 3
y-axis
     [tex]R_y[/tex] = [tex]\frac{15 -0 }{20}[/tex]15-0 / 20
     [tex]R_y[/tex] = 0.75
In the attachment we have a diagram of the axes of the graph, to avoid that the values ​​are very saturated, some have been placed in a spaced way.
In conclusion using the rules for a good graph we can find that the scales in for the two axes are
- x-axis    3 values ​​/ box
- y axis    0.75 values ​​/ box
