+- `fixed_width_lbl=NUMBER` and `fixed_width_val=NUMBER`
+
+ This parameter overrides auto-sizing of badges and displays them at fixed widths. `fixed_width_lbl` determines the size of the label's left side (label/name). `fixed_width_val` determines the size of the the label's right side (value). You must set both parameters together, or they will be ignored.
+
+ You should set the label/value widths wide enough to provide space for all the possible values/contents of the badge you're requesting. In case the text cannot fit the space given it will be clipped.
+
+ The `scale` parameter still applies on the values you give to `fixed_width_lbl` and `fixed_width_val`.
+
- `refresh=auto` or `refresh=SECONDS`
This option enables auto-refreshing of images. Netdata will send the HTTP header `Refresh: SECONDS` to the web browser, thus requesting automatic refresh of the images at regular intervals.
