It looks like the screenshot attachment has failed as there is not such attachment to your response.
We are not sure what you mean by display outside of the ganttbar. You can take a look at our help article about "Configuring the TimeRuler
" which illustrates how to change the size of that part in the control. Hope this is helpful.
If we have missed something could you please describe the scenario in greater detail and attache the mentioned screenshot to this thread.
