I have a 4-column view in which each column is a custom object resource displaying interface bandwidth utilization. On some resources, the Y-axis doesn't show the throughput labels.
Here's an example:

In this case, the peak represents about 7 Mbps.
On other resources, a Y-axis label is displayed. Does anyone know why the labels are displayed on some resources but not others? It appears random to me. I'd like it displayed on all of them.
