Value Type

By default, the Y Axis Type is “Numeric” : this means that the Y position of points directly maps to the numeric value of the Y Value Series data field.

The Type “Logarithmic” can also be selected : this means that the Y position maps to the logarithm of the Y Value Series data field.

For example, here is a simple chart with Y Axis as “Numeric” (default) and X Axis as “Category” (default) :

The variations happen on many orders of magnitude, and it’s difficult to track what is the real trend.
With a “Logarithmic” Value Type of the Y Axis, and Numeric for the X Axis, we see that the trend is exactly exponential :

Force Axis To Start at 0

By default, the minimum and maximum value of the Y Axis is automatically calculated to scale to the data displayed.
Instead, you can force the zero to always be included on the Y Axis.
This is useful for example if you want to display absolute variations compared to the total value.

To enable this behavior, check Force Axis To Start at 0 :

Custom Range

By default, the minimum and maximum value of the Y Axis is automatically calculated to scale to the data displayed.
Instead, you can force a Custom Range :
