Problem with Dashboard Test

I’ve used this script to configue Basic dashboard Test control


dataTypes:
motd:
msg: string
monitor: # new data type
cpu: float
mem: integer

screens:

    • message
    • graph
    • interface # new screen

widgets:
message:
display: label
type: motd
key: msg
label: from device
graph:
display: line
type: monitor
keys: cpu, mem
label: Device Status
interface:
control: button
map:
- event: increasePower
value: + CPU
- event: decreasePower
value: - CPU
label: Device Control


Then I typed " Matrix deploy "

But it always show me bad indentation of a sequence entry at line 42, column 16:
value: - CPU

What’s the problem?

And other question is how to change the value and the Interval data of Y-axis?
