Controlling the Chart Type

In this section: |

The recommended way to establish the chart type is to include the LOOKGRAPH parameter in your request.

FOCUS provides parameters for controlling many other chart properties, as well. Most of these also have JSON equivalents. In all cases, the best practice is to use FOCUS syntax where possible and JSON properties when a FOCUS parameter does not exist for the desired property.

Controlling Chart Type Using LOOKGRAPH

How to: Reference: |

With a few exceptions, each GRAPH request must include a sort phrase (dimension) and at least one display field (measure).

The fields that are the subjects of the chart can be real or virtual fields, with or without direct operator prefixes (for example, AVE., MIN., MAX.). They can also be calculated values.

Note: Display fields used only for calculations need not appear in the chart. You can use the NOPRINT phrase to suppress the display of such fields.

The LOOKGRAPH parameter enables you to change the format of the graph without having to set individual control parameters or restructure the graph request. However, even if you use LOOKGRAPH, you can choose to set individual control parameters (for example, SET GRID=ON).

Syntax: How to Specify a Chart Type Using LOOKGRAPH

Prior to the request, use the following syntax

`SET LOOKGRAPH= type`

Or, within the request, use the following syntax

`ON GRAPH SET LOOKGRAPH type`

where:

- type
Is the chart type you want to generate.

For a complete list of LOOKGRAPH values, see the Creating Reports manual. The following sections list the most useful LOOKGRAPH values for creating HTML5 charts.

Reference: HTML5-Only Chart Types

The following LOOKGRAPH values are valid only when generating an HTML5 chart:

SET LOOKGRAPH |
Description |
---|---|

BUBBLEMAP |
A bubblemap is a chart in which proportionally sized bubbles are displayed on relevant areas of the map. |

CHOROPLETH |
A choropleth is a chart in which areas on a map are shaded or patterned in proportion to the value of the measure being represented. |

MEKKO |
A Mekko chart is a variant of a stacked bar chart, in which the width of the bars is adjusted relative to its value in the data set. |

PARABOX |
A Parabox (or parallel coordinates chart) is similar to a regular line chart, except that each group in the line chart has a unique and interactive numeric axis. Each line represents one series of data. Each vertical bar represents a numeric axis. You can click and drag along each of the axes to select (filter) the lines that pass through that part of the axis |

STREAM |
A streamgraph is a simplified version of a stacked area chart. In a streamgraph, there are no axes, gridlines, or frames. The baseline is free, which makes it easier to perceive the thickness of any given layer across the data. |

TAGCLOUD |
A tagcloud is a visual representation of frequency. It displays only group labels. The size of each label is proportional to its data value. |

TREEMAP |
A treemap chart displays hierarchical data as a set of nested rectangles. |
