projectFrom() ​

ts
projectFrom(
   point, 
   options?, 
   cache?
): D3PRangePoint | undefined;

Defined in: core/coords.ts:90

Parameters ​

point ​

D3PViewportPoint

options? ​
strict? ​

boolean

cache? ​

D3PProjectionCache

Returns ​

D3PRangePoint | undefined

projectTo() ​

ts
projectTo(
   chart, 
   a, 
   b, 
   cache?
): D3PViewportPoint;

Defined in: core/coords.ts:85

Range units to a viewport point.

Parameters ​

chart ​
