The bar charts are currently taking up the full width of the page, but the dashboard definition actually specifies that they should have just half of the page width.
The four charts Current Rate of Bytes Received & Current Rate of Bytes Transmitted & Average Rate of Bytes Received & Average Rate of Bytes Transmitted on the "Kubernetes / Networking / Cluster" dashboard show well with expected width. 4.5.0-0.ci-2020-03-03-032706
