// V9 migration removes the first threshold value from singlestat panel thresholds when they have 3 or more values.
|
|
// This migration aligns with the frontend schema version 9 changes that addressed aliasYAxis changes
|
|
// specifically for singlestat panels with threshold configurations.
|
|
//
|
|
// Background:
|
|
// In earlier versions, singlestat panels stored threshold values as comma-separated strings with the first element
|
|
// representing a baseline value that was not actually used in threshold calculations. This migration removes that
|
|
// unused first element to clean up the data structure.
|
|
//
|
|
// Example before migration:
|
|
// {
|
|
// "schemaVersion": 8,
|
|
// "panels": [
|
|
// {
|
|
// "type": "singlestat",
|
|
// "thresholds": "10,20,30"
|
|
// }
|
|
// ]
|
|
// }
|
|
//
|
|
// Example after migration:
|
|
// {
|
|
// "schemaVersion": 9,
|
|
// "panels": [
|
|
// {
|
|
// "type": "singlestat",
|
|
// "thresholds": "20,30"
|
|
// }
|
|
// ]

|
