Log Scale

This option should be used when the range of your data is very broad. When checked, the values are displayed using a logarithmic scale rather than using the actual values so that data on the extreme ends of the scale can be viewed more effectively. For example, if you have data that ranges from the tens to the thousands, the data in the range of the tens will be neglected visually if you do not check this option.

 

 

 

Base at Zero

When this option is checked, zero is set as the as the Y axis minimum for all graph traces.
