Description of problem:
In the dev console when there is minimal/no data, most of the monitoring charts (CPU/memory use, bandwidth, etc) show a range of -1 to 1. None of these values can ever go below zero so the default looks very odd, and changes/jumps quite a bit the moment there is any data.
Steps to Reproduce:
Look at a pod that hasn't had any activity or scale one to zero.
Default charts show range of -1 to 1 with no units.
When there is data the graph changes completely and adds units.
Option 1 - The bottom end of the range should be 0 for all of these charts, and ideally have unit labels (e.g. memory could be 0M to 1M)
Option 2 - If there is no data, show 'no data' instead of showing a chart.
Moving to 4.8 as we likely can't get this into 4.7 due to bandwidth.
