I want some value not to be shown on the line。 the line is discontinuous

This issue has no description.

The issue has no body, reproduction, file, or test reference. Start by clarifying which chart type and value should be hidden, then locate the relevant Swift line-chart behavior and define the expected discontinuity. Done means the requested value is omitted without rendering a misleading connecting line, with regression coverage for the confirmed case.
