Show disks per computer as graph

[cmptscpeacock]

Hi

I have these Log Analytics queries that show the space per disk per computer. How can I render a timechart showing each disk of each computer?

Currently:

InsightsMetrics
| where Origin == "vm.azm.ms"
| where Namespace == "LogicalDisk" and Name == "FreeSpacePercentage"
| extend Disk=tostring(todynamic(Tags)["vm.azm.ms/mountId"])
| project TimeGenerated, Computer, Disk, Val

When I add render timechart we see what looks to be a total or average of all the disks per vm, rather than each disk of each vm:

InsightsMetrics
| where Origin == "vm.azm.ms"
| where Namespace == "LogicalDisk" and Name == "FreeSpacePercentage"
| extend Disk=tostring(todynamic(Tags)["vm.azm.ms/mountId"])
| project TimeGenerated, Computer, Disk, Val
| render timechart

TIA!
