How to rename axes in Azure Log Analytics Timechart Query

Question

I have the following query that I want to change the name of the axes. I tried the optional attributes of render, but it doesn't seem to recognize any of them. What am I missing?

AzureStorage_CL
| where ResourceGroup == "rg-sdl-adw"
| where PercentClientOtherError_d > 0
| summarize AV = any(PercentClientOtherError_d) by bin(TimeGenerated, 30m) | 
render timechart with (ytitle = "Y new title")

Current results:

Answer 1

The "ytitle" isn't supported in Log Analytics since it uses a different rendering engine.

An issue has been submitted to track it.

Answer 2

Did you get your answer to this?

The axis aren't easy to edit, and the format you are constrained by are a bit restrictive, but essentially you need to rename the axes by taking your query:

AzureStorage_CL
| where ResourceGroup == "rg-sdl-adw"
| where PercentClientOtherError_d > 0
| summarize AV = any(PercentClientOtherError_d) by bin(TimeGenerated, 30m) 
| render timechart

Now add in an extra line to rename the axis | project-rename NewAxisTitle = AV where the NewAxisTitle is your desired name, and the AV is your old name:

AzureStorage_CL
| where ResourceGroup == "rg-sdl-adw"
| where PercentClientOtherError_d > 0
| summarize AV = any(PercentClientOtherError_d) by bin(TimeGenerated, 30m)
| project-rename NewAxisTitle = AV
| render timechart

Be aware that any time you refer to the axis after the point you rename it you need to refer to it as it's new name.

Hope that all makes sense.
