Hello,

You are trying to add a wheel so you want to show a percentage value. Can you open the Expression Editor and add a `max` property to the `progress` function?

I think the issue you are seeing is not directly related with the problem, you just need to add a max value so Canvas knows which percentage to render (a count of timestamps in your screenshot).

Sharing the code here in case you want to test against the logs sample dataset

```auto
kibana
| selectFilter
| esdocs index="kibana_sample_data_logs" fields="timestamp, ip" sort="timestamp, DESC"
| math "size(ip)"
| progress shape="wheel" label={formatnumber "0"} max=10000
  font={font size=24 family="'Open Sans', Helvetica, Arial, sans-serif" color="#000000" align="center"}
| render

```
