This requires digging down into the chart object itself.  
Assuming one plot and one defined axis (otherwise, you would need to use an index number for each).

```python
# Get the chart component object
component = event.source.parent.getComponent('Chart')

# Get chart data
chart = component.getChart()

# Get the plot settings
plot = chart.getPlot()

# Get the axis settings
axis = plot.getRangeAxis()

# Now that we have the axis, we can set different things. 

# Set the upperMargin
axis.setUpperMargin(0.5)

# Turn off auto range
axis.setAutoRange(0)

# set upper and lower bounds
axis.setUpperBound(1000)
axis.setLowerBound(500)

```
