// V37 normalizes legend configuration to use `showLegend` property consistently.
|
|
//
|
|
// This migration addresses inconsistencies in how legend visibility was handled.
|
|
// There were two ways to hide the legend:
|
|
// 1. Using displayMode: "hidden"
|
|
// 2. Using showLegend: false
|
|
//
|
|
// The migration normalizes both approaches to use showLegend consistently:
|
|
// - If displayMode is "hidden" OR showLegend is false, set displayMode to "list" and showLegend to false
|
|
// - For all other existing legend objects, ensure showLegend is true
|
|
//
|
|
// Note: This migration only processes legend configurations that already exist as objects.
|
|
// Boolean legend values are not processed by this migration.
|
|
//
|
|
// Example transformations:
|
|
//
|
|
// Before migration (hidden displayMode):
|
|
//
|
|
// options: {
|
|
// legend: {
|
|
// displayMode: "hidden",
|
|
// placement: "bottom"
|
|
// }
|
|
// }
|
|
//
|
|
// After migration:
|
|
//
|
|
// options: {
|
|
// legend: {
|
|
// displayMode: "list",
|
|
// showLegend: false,
|
|
// placement: "bottom"
|
|
// }
|
|
// }
|
|
//
|
|
// Before migration (showLegend false):
|
|
//
|
|
// options: {
|
|
// legend: {
|
|
// displayMode: "table",
|
|
// showLegend: false
|
|
// }
|
|
// }
|
|
//
|
|
// After migration:
|
|
//
|
|
// options: {
|
|
// legend: {
|
|
// displayMode: "list",
|
|
// showLegend: false
|
|
// }
|
|
// }
|
|
//
|
|
// Before migration (visible legend):
|
|
//
|
|
// options: {
|
|
// legend: {
|
|
// displayMode: "table",
|
|
// placement: "bottom"
|
|
// }
|
|
// }
|
|
//

//
|
|
// options: {

// legend: {
|

// showLegend: true
