On a Line > Line visualization, the minimum axis value defaults to 0 when no specification has been made on Chart > VALUES (Y) AXIS > Minimum Value.
Here is video of replication / discussion.
To replicate:
Step 1: Using cola tracking.
Step 2: Open Displayr project and create a crosstab table (any two variables will do).
Step 3: Insert Line > Line and use the table created in Step 2 as input.
Step 4: Note that the vertical axis starts at 0 even though it is expected to adjust closer to the minimum value (as it does for max).

Workaround:
Step 1: 
Insert this on line 196 before the chart is created:
{noformat}#calculate the minimum from Column %
minval = verbs::Min(pd$data[,,"Column %"])*.9/100{noformat}
Step 2: 
Near line 444, where {{values.bounds.minimum}} is set, comment out the line there and set it equal to the calculated value, should look like:
{noformat}#values.bounds.minimum = get0("formValuesMin"),
values.bounds.minimum = minval,{noformat}
