I have a database TAChart with two panes. the bottom axis is a Date common to both panes. The two left axis use different fields. I set the logical extent for the bottom axis to the last 5% of the data. The y axis of both panes is being automatically set to the lowest and highest values of the full extent of the data returned by the Query accessing the database - I would like to set them to the highest and lowest values of just the data displayed and have this adjust when panning. I am using an axistransformation for each pane. Any help will be appreciated.
