Support turning off column/bar baseline

Version: 2020b

Type: Features

Category: Graphing

Subcategory: Column/Bar/Pie

Jira: ORG-19651

Origin uses the Additional Y= line on Grids tab of Axis dialog to control where column/bar is plotted from. In the past, the baseline can not be hidden. Origin 2020b supports uncheck the checkbox to hide it but still use it as baseline.
