[EricTsuei]

I have edit the source py file in:

C:\Program Files\Southpaw\tactic\src\tactic\ui\chart\sobject_chart_wdg.py

in line 288

original:
chart_labels.append( sobject.get_code() ) 
to this:
chart_labels.append( sobject.get_value(my.x_axis))

seems x_axis display correctly.
please see the attachment.
I don't know I am doing the right thing or not. please tell me.
