isc.Calendar customization

Hi,
I'm using the isc.Timeline component for the first time and I can´t change the height and width of each cell. I have looking in ISC_Calendar.js (column width 60px) and it seems to be hardcoded.

Is it possible to change the height and width of the cells for all the component?

im usign this example:
