This operation removes all column override settings including color gradients, precision configurations, and visibility settings. After deletion, the experiment view will revert to default column display settings. This action cannot be undone - you will need to recreate the override configuration if you want to restore custom column settings. Both the dataset and override must exist and be accessible by the authenticated user. The operation will fail if the override doesn't exist or if the user doesn't have appropriate permissions for the dataset. ## OpenAPI ````yaml /langsmith/langsmith-platform-openapi.json delete /datasets/{dataset_id}/experiment-view-overrides/{id} openapi: 3.1.0 info: title: LangSmith description: >+ The LangSmith API is used to programmatically create and manage LangSmith resources. ## Host https://api.smith.langchain.com ## Authentication To authenticate with the LangSmith API, set the `X-Api-Key` header to a valid [LangSmith API key](https://docs.langchain.com/langsmith/create-account-api-key#create-an-api-key). version: 0.1.0 servers: - url: / security: [] tags: - name: run x-group: Tracing - name: runs x-group: Tracing - name: sessions x-group: Tracing - name: tracer-sessions x-group: Tracing - name: datasets x-group: Datasets - name: examples x-group: Datasets - name: evaluators x-group: Evaluation - name: experiment-view-overrides x-group: Evaluation - name: experiments x-group: Evaluation - name: annotation-queues x-group: Feedback & Annotation - name: annotation_queues x-group: Feedback & Annotation - name: feedback x-group: Feedback & Annotation - name: feedback-configs x-group: Feedback & Annotation - name: alert_rules x-group: Monitoring - name: bulk-exports x-group: Monitoring - name: charts x-group: Monitoring - name: commits x-group: Prompts & Playground - name: directories x-group: Prompts & Playground - name: hub_environments x-group: Prompts & Playground - name: playground-settings x-group: Prompts & Playground - name: prompt-webhooks x-group: Prompts & Playground - name: prompts x-group: Prompts & Playground - name: tag-transitions x-group: Prompts & Playground - name: comments x-group: Prompt Hub - name: likes x-group: Prompt Hub - name: optimization-jobs x-group: Prompt Hub - name: ownerships x-group: Prompt Hub - name: repos x-group: Prompt Hub - name: settings x-group: Prompt Hub - name: tags x-group: Prompt Hub - name: integrations x-group: Integrations & Tools - name: mcp x-group: Integrations & Tools - name: mcp_vendors x-group: Integrations & Tools - name: oauth x-group: Integrations & Tools - name: tools x-group: Integrations & Tools - name: gateway-policies x-group: LLM Gateway - name: sandboxes x-group: Sandboxes - name: issues x-group: Issues - name: issues-agent x-group: Issues - name: Organizations x-group: Administration - name: SCIM Tokens x-group: Administration - name: TTL Settings x-group: Administration - name: access_policies x-group: Administration - name: api-key x-group: Administration - name: audit-logs x-group: Administration - name: auth x-group: Administration - name: aws_marketplace x-group: Administration - name: data_planes x-group: Administration - name: me x-group: Administration - name: orgs x-group: Administration - name: service-accounts x-group: Administration - name: tenant x-group: Administration - name: ttl-settings x-group: Administration - name: usage-limits x-group: Administration - name: workspaces x-group: Administration - name: ace x-group: System - name: backfills x-group: System - name: features x-group: System - name: info x-group: System - name: model-price-map x-group: System - name: public x-group: System - name: threads x-group: System - name: agents x-hidden: true - name: beacon x-hidden: true - name: engine-trial - name: fleet - name: fleet auth x-hidden: true - name: fleet credentials x-hidden: true - name: fleet github-app x-hidden: true - name: fleet integrations x-hidden: true - name: fleet mcp x-hidden: true - name: fleet threads x-hidden: true - name: fleet trigger-templates x-hidden: true - name: fleet triggers x-hidden: true - name: fleet usage x-hidden: true - name: fleet_webhooks x-hidden: true - name: health - name: internal x-hidden: true - name: metrics x-hidden: true - name: nps x-hidden: true - name: sandboxes-internal x-hidden: true - name: skills x-hidden: true paths: /datasets/{dataset_id}/experiment-view-overrides/{id}: delete: tags: - experiment-view-overrides summary: Delete experiment view override configuration description: >- Permanently deletes an experiment view override configuration for a dataset.
