Class VisualizeImageChartRequest

java.lang.Object

com.gpudb.protocol.VisualizeImageChartRequest

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.

Constructs a VisualizeImageChartRequest object with the specified parameters.

Parameters:

tableName - Name of the table containing the data to be drawn as a chart.

xColumnName - Name of the column containing the data mapped to the x axis of a chart.

yColumnName - Name of the column containing the data mapped to the y axis of a chart.

minX - Lower bound for the x column values. For non-numeric x column, each x column item is mapped to an integral value starting from 0.

maxX - Upper bound for the x column values. For non-numeric x column, each x column item is mapped to an integral value starting from 0.

minY - Lower bound for the y column values. For non-numeric y column, each y column item is mapped to an integral value starting from 0.

maxY - Upper bound for the y column values. For non-numeric y column, each y column item is mapped to an integral value starting from 0.

width - Width of the generated image in pixels.

height - Height of the generated image in pixels.

bgColor - Background color of the generated image.

styleOptions - Rendering style options for a chart.

• POINTCOLOR: The color of points in the plot represented as a hexadecimal number.

  • HOLLOWDIAMOND
  The default value is SQUARE.
• CB_POINTCOLORS: Point color class break information consisting of three entries: class-break attribute, class-break values/ranges, and point color values. This option overrides the pointcolor option if both are provided. Class-break ranges are represented in the form of "min:max". Class-break values/ranges and point color values are separated by cb_delimiter, e.g. {"price", "20:30;30:40;40:50", "0xFF0000;0x00FF00;0x0000FF"}.

This option overrides the pointsize option if both are provided. Class-break ranges are represented in the form of "min:max". Class-break values/ranges and point size values are separated by cb_delimiter, e.g. {"states", "NY;TX;CA", "3;5;7"}.
• CB_POINTSHAPES: Point shape class break information consisting of three entries: class-break attribute, class-break values/ranges, and point shape names. This option overrides the pointshape option if both are provided. Class-break ranges are represented in the form of "min:max". Class-break values/ranges and point shape names are separated by cb_delimiter, e.g. {"states", "NY;TX;CA", "circle;square;diamond"}.
• CB_DELIMITER: A character or string which separates per-class values in a class-break style option string.
• X_ORDER_BY: An expression or aggregate expression by which non-numeric x column values are sorted, e.g. "avg(price) descending".
• Y_ORDER_BY: An expression or aggregate expression by which non-numeric y column values are sorted, e.g. "avg(price)", which defaults to "avg(price) ascending".
• JITTER_X: Amplitude of horizontal jitter applied to non-numaric x column values.
• JITTER_Y: Amplitude of vertical jitter applied to non-numaric y column values.
• PLOT_ALL: If this options is set to "true", all non-numeric column values are plotted ignoring min_x, max_x, min_y and max_y parameters.

options - Optional parameters.
