autumnplot-gl / RawScalarField
A class representing a raw 2D field of gridded data, such as height or u wind.
• ArrayType extends TypedArray
new RawScalarField<
ArrayType>(grid,data):RawScalarField<ArrayType>
Create a data field.
• grid: Grid
The grid on which the data are defined
• data: ArrayType
The data, which should be given as a 1D array in row-major order, with the first element being at the lower-left corner of the grid.
RawScalarField<ArrayType>
readonlydata:ArrayType
readonlygrid:Grid
getContours(
opts):Promise<ContourData>
• opts: FieldContourOpts
Promise<ContourData>
staticaggregateFields<ArrayType>(func, …args):RawScalarField<ArrayType>
Create a new field by aggregating a number of fields using a specific function
• ArrayType extends TypedArray
• func
A function that will be applied each element of the field. It should take the same number of arguments as fields you have and return a single number.
• …args: RawScalarField<ArrayType>[]
The RawScalarFields to aggregate
RawScalarField<ArrayType>
a new gridded field
// Compute wind speed from u and v
wind_speed_field = RawScalarField.aggreateFields(Math.hypot, u_field, v_field);
