Graphs in Resource Horizontal Plan

Hi.

When we view the horizontal plan for a particular resource/workcenter in ASCP workbench, we can also see graphs. The graphs however are very difficult to read and small. Is it possible by way of some setup to make them look bigger (by say increasing the scale) and also show some comment on what they are for. On the x axis we see some numbers at the end of the x axis but not sure what they are for.

Thanks
