plotter-data

Function

(plotter-data plotter {keyword value}*)

Returns the data sets loaded in plotter according to keyword arguments.

plotter-data supports the following keyword arguments:

:layer {:front | :front-selection | index}: If :layer is not specified then data from all layers are returned. If only one layer exists, or if :layer is :front then only the front layers's data is returned. If :layer is :front-selection then only the currently selected points (if any) in the front layer are returned. Otherwise the value should be the zero-based index of the layer to return. Layers are stored in the order they were created.
:xy boolean: Determines if CLOS objects or xy coordinate numbers are returned as data. If :xy is not specified then point data are converted to xy coordinate values but other CLOS instances are not. If the value is false then layer objects are returned. If the value is true then numerical coordinate values are returned and the value of :x-decimals and :y-decimals determines their value formatting.
:x-decimals {boolean | integer}: Specifies the number of decimal places to which x values in :xy coordinate lists are rounded to (if :xy is true). If boolean true (the default) then x values are unchanged. If false then x values are floored to the nearest integer. Otherwise the value should the number of decimal places that data values are rounded to. Specifying zero causes data to remain floating point but without remainder.
:y-decimals {boolean | integer}: Exactly like :x-decimals except that it applies to y values.
