All Implemented Interfaces:

org.apache.avro.generic.GenericContainer, org.apache.avro.generic.IndexedRecord

public class VisualizeImageChartRequest
extends Object
implements org.apache.avro.generic.IndexedRecord

A set of parameters for GPUdb.visualizeImageChart(VisualizeImageChartRequest).

Scatter plot is the only plot type currently supported. A non-numeric column can be specified as x or y column and jitters can be added to them to avoid excessive overlapping. All color values must be in the format RRGGBB or AARRGGBB (to specify the alpha value). The image is contained in the imageData field.

  • NONE: No scale is applied to the y axis.
  • LOG: A base-10 log scale is applied to the y axis.
  The default value is NONE.
• MIN_MAX_SCALED: If this options is set to "false", this endpoint expects request's min/max values are not yet scaled. They will be scaled according to scale_type_x or scale_type_y for response.
