Options

Flexmonster's appearance can be defined within the report. Options are used to specify the appearance and functionality available to users. For example, you can show/hide features such as filters and sorting controls, define date patterns, or enable/disable the drill-through.

Options are defined in an OptionsObject inside the report. If no options are specified, Flexmonster will use the default options. This tutorial explains which options are available and how to use them.

Our default options are defined automatically, so you only need to define the options you want to modify. All options can be divided into three subgroups:

Grid options – define the grid’s appearance and functionality.
Chart options – define the chart’s appearance and functionality.
Component-wide options – define the options applicable to the whole component.

Read this section to learn how to set the options. The default options section contains an example of Flexmonster’s default options.

Visit our Examples page for live examples that demonstrate how to use different options.

Grid options

All grid options are in the grid section of the options object.

Chart options

All chart options are in the chart section of the options object.

Available chart options

Option	Description
chart.type	String. The selected chart type. The following chart types are supported: `"column"`, `"bar_h"`, `"line"`, `"scatter"`, `"pie"`, `"stacked_column"`, and `"column_line"`. Default value: `"column"`.

chart.showDataLabels	Boolean. Setting this value to `true` allows showing labels in charts. If the value is `false`, the labels will be hidden. Use `showAllLabels` to configure the labels in a pie chart. Default value: `false`.
chart.showAllLabels	Boolean. Setting this value to `true` allows showing all the labels in a pie chart. If the value is `false` then only the labels that can be shown without overlapping will be shown. Default value: `false`.
chart.showMeasures	Boolean. Hides all dropdowns on the top of the charts. This is useful if you want to show a simple chart without any controls or if you want to save space. When set to `true`, the dropdowns are visible. Default value: `true`.
chart.showOneMeasureSelection	Boolean. When set to `true`, the measures dropdown is always visible - regardless of the number of measures in it. If the value is set to `false`, the measures dropdown on charts will be hidden if there is only one measure in the list and visible if there are two or more measures. Default value: `true`.
chart.showWarning	Boolean. Indicates whether warnings are shown if the data is too big for charts. Default value: `true`.
chart.position	String. The positions of the charts in relation to the grid. It can be `"bottom"`, `"top"`, `"left"`, or `"right"`. Default value: `"bottom"`.
chart.activeMeasure	Object \| Array of objects. Identifies the measures selected for the chart. By default, `activeMeasure` is an object. If the chart.multipleMeasures option is set to `true`, `activeMeasure` is an array of objects. Each object has the `uniqueName` and `aggregation` properties. They are described below.
chart.activeMeasure.uniqueName	String. The unique measure name. This measure must be present in the slice.measures property.
chart.activeMeasure.aggregation	String. The measure aggregation type. This aggregation must be defined for the measure in the slice.measures.aggregation property.
chart.pieDataIndex	String. The selected column member index. Learn more about the pie chart structure. Indexes start from `"0"` (the first member of a column field). If `pieDataIndex` is set to a non-existing index, the default index will be used. Default value: `"0"`.

Component-wide options

All the component-wide options are in the options object.

Available component-wide options

Option	Description
viewType	String. The type of view to show: `"grid"` or `"charts"` or `"grid_charts"` (starting from v1.9). Default value: `"grid"`.
filter	Object. Filtering options:
filter.weekOffset	Number. Sets the number of days to be added to the start of the week (Sunday). Used to adjust the first day of the week in the filter’s calendar. Default value: `1` (Monday is the first day of the week).
filter.dateFormat	String. The date pattern to use to format dates in the filter’s date inputs. Has two possible values: `"dd/MM/yyyy"` and `"MM/dd/yyyy"`. Default value: `"dd/MM/yyyy"`.
filter.liveSearch	Boolean. Indicates whether the search in the filter pop-up window is performed while the user types (`true`) or requires the Enter button to start searching (`false`). Default value: `true`.
configuratorActive	Boolean. Indicates whether the Field List is opened (`true`) or closed (`false`) after the component is initialized. Default value: `false`.
configuratorButton	Boolean. Indicates whether the Field List toggle button is visible (`true`) or not (`false`). Default value: `true`.
showAggregations	Boolean. Indicates whether the aggregation selection control is visible (`true`) or not (`false`) for measures on the Field List. Default value: `true`.
showCalculatedValuesButton	Boolean. Controls the visibility of “Add calculated value” in the Field List. Default value: `true`.
showEmptyValues	Boolean \| String. Specifies where to show members with empty values on the grid and charts: in rows (`"rows"`), in columns (`"columns"`), in rows and columns (`true`), or not at all (`false`). To configure this behavior for a specific field, use the showEmptyValues property in the mapping. Only for `"json"`, `"csv"`, and `"api"` data source types. If you are using the `"api"` data source type, there are specifics of how this property affects multilevel hierarchies: When using Flexmonster Data Server, `showEmptyValues` is ignored for multilevel hierarchies. When implementing the custom data source API, `showEmptyValues` will affect multilevel hierarchies if you specify their members with empty values in the aggs property of the response to the /select request for the pivot table. For example: "aggs": [ … { "keys": { "Country": "United States", "City": "Los Angeles" }, "values": {} }, … ], Default value: `false`.
editing	Boolean. Indicates whether the editing feature is enabled (`true`) or disabled (`false`). Editing is available only in the drill-through view and the flat form. If the editing feature is enabled, the user will be able to double-click the cell and enter a new value into it. Only for `"json"` and `"csv"` data source types. Default value: `false`.
drillThrough	Boolean. Indicates whether the drill-through feature is enabled (`true`) or disabled (`false`). The user can drill through by double-clicking the cell with a value. Default value: `true`.
showDrillThroughConfigurator	Boolean. Indicates whether the Field List toggle button is visible in the drill-through view. Only for `"csv"`, `"json"`, `"api"`, `"microsoft analysis services"` (for Flexmonster Accelerator), and `"elasticsearch"` data source types. Default value: `true`.
sorting	String. Indicates whether the sorting controls are visible in rows (`"rows"`), in columns (`"columns"`), in rows and columns (`"on"` or `true`) on the grid cells, or not visible at all (`"off"` or `false`). Default value: `"on"`.
readOnly	Boolean. When set to `true`, enables the read-only mode for the component. In the read-only mode, you cannot interact with the report via UI (e.g., the context menu, expands, and drills are disabled). In addition, configurations of the following options are ignored: `showFilter` (for both grid and charts), `dragging`, `showMeasures`, `configuratorButton`, `sorting`, and `drillThrough`. We also suggest hiding the Toolbar when using the read-only mode. Default value: `false`.
strictDataTypes	Boolean. When set to `true`, the component treats fields marked as a measure only as measures and does not allow using them as hierarchies. This allows increasing data analyzing speed. To mark a field as a measure, set its isMeasure property in the mapping to `true`. Check out an example. Only for the `"json"` data source type. Default value: `false`.
distinguishNullUndefinedEmpty	Boolean. Allows distinguishing null, undefined, and empty values. When set to `false`, the component treats null, undefined, and empty values as the same value. When set to `true`, there are three different values. Default value: `false`.
defaultDateType	String. Used to specify which data types should be applied to date fields by default (`"date"`, `"date string"`, `"year/month/day"`, `"year/quarter/month/day"`, or `"datetime"`). Only for `"json"` and `"csv"` data source types. Default value: `"date"`.
datePattern	String. Allows specifying how the component displays fields of the `"date string"` type. Only for `"json"`, `"csv"`, `"api"`, and `"elasticsearch"` data source types. Default pattern string: `"dd/MM/yyyy"`. Learn more about date and time formatting.
dateTimePattern	String. Allows specifying how the component displays fields of the `"datetime"` type. Only for `"json"`, `"csv"`, and `"api"` data source types. Default pattern string: `"dd/MM/yyyy HH:mm:ss"`. Learn more about date and time formatting.
timePattern	String. Allows specifying how the component displays fields of the `"time"` type. Only for `"json"`, `"csv"`, and `"api"` data source types. Default pattern string: `"HH:mm:ss"`. Learn more about date and time formatting.
dateTimezoneOffset	Number. Allows setting a time zone for all date fields in the dataset. The `dateTimezoneOffset` is a number that represents the difference in hours between the needed time zone and UTC. See an example on JSFiddle. Besides, you can also set time zones for fields of a certain type and specific fields. These time zones will have different priorities. Learn more in our guide.
saveAllFormats	Boolean. If there are more than 20 formats defined, only the formats that are used for `"active: true"` measures will be saved in the report. In order to save all the formats, set the `saveAllFormats` property to `true`. Default value: `false`.
showDefaultSlice	Boolean. Defines whether the component selects a default slice for a report with an empty slice (when nothing is set in rows, columns, report filters, and measures). If `true`, the first hierarchy from data goes to rows and the first measure goes to columns in the default slice. To avoid this default behavior, set this property to `false`. Only available for `"csv"` and `"json"` data source types. Default value: `true`.
useOlapFormatting	Boolean. Indicates whether the values from data source will be formatted according to the format defined in the cube (`true`) or not (`false`). Default value: `false`.
showMemberProperties	Boolean. Indicates whether the member properties for an OLAP data source are available in the component (`true`) or not (`false`). This feature is only for the `"microsoft analysis services"` data source type. Default value: `false`.
showEmptyData	Boolean. Indicates how the component behaves for the following data sources: An empty JSON/CSV file. An empty JSON array. A CSV file where only the header row is defined. An OLAP cube that returns empty data. When `showEmptyData` is set to `true`, an empty grid is shown for such data sources. When set to `false`, the component displays a pop-up error message and triggers one of the following events: dataerror for `"json"` and `"csv"` data source types. queryerror for the `"microsoft analysis services"` data source type. See an example on JSFiddle. Default value: `true`.
defaultHierarchySortName	String. The sorting type for hierarchies’ members (`"asc"`, `"desc"`, or `"unsorted"`). Default value: `"asc"`.
showOutdatedDataAlert	Boolean. Setting this value to `true` will show a warning to the user before automatic reloading of data from the cube. There will be no warnings if set to `false`. Only for Flexmonster Accelerator. Default value: `false`.
expandExecutionTimeout	Number. Allows specifying an execution timeout for the expandAllData() function. The timeout is set in milliseconds (i.e., `9000` equals 9 seconds). The minimum timeout value is `9000`. Note that a large execution timeout can cause an unresponsive script alert. Default value: `9000`.
showAggregationLabels	Boolean. Indicates whether aggregation labels like `"Total Sum of"`, `"Sum of"`, etc. are shown in the column/row titles. Default value: `true`.
showAllFieldsDrillThrough	Boolean. Indicates whether prefiltering the drill-through view columns is enabled (`false`) or if the drill-through view displays all the available columns (`true`) when using SSAS with Flexmonster Accelerator. Default value: `false`.
liveFiltering	Boolean. Indicates whether the live filtering for hierarchies' members is enabled (`true`) or disabled (`false`). Default value: `false`.
showFieldListSearch	Boolean. Indicates whether the search bar in the Field List is shown (`true`) or hidden (`false`). When the search bar is hidden, it will be shown only when the number of the hierarchies exceeds 50 (or 40 for the flat form). Default value: `false`.
useCaptionsInCalculatedValueEditor	Boolean. By default, Flexmonster uses field unique names in the calculated value editor. If `useCaptionsInCalculatedValueEditor` is set to `true`, the component will use field captions instead of unique names. Default value: `false`.
validateFormulas	Boolean. Indicates whether validation is performed for calculated values (`true`) or not (`false`). If validation is turned on and the report contains an invalid formula, the “Wrong formula format” alert message is shown. Default value: `true`.
caseSensitiveMembers	Boolean. Indicates whether the hierarchies' members are case-sensitive (`true`) or not (`false`). Default value: `false`.
simplifyFieldListFolders	Boolean. Indicates whether the folders containing one field should show this field in the root (`true`) or not (`false`). Only for Elasticsearch and SSAS data sources. Default value: `false`.
validateReportFiles	Boolean. Indicates whether validation of report files is turned on (`true`) or turned off (`false`). Setting this value to `false` allows loading report files in the old format without an error message. Should be used in global options. Default value: `true`.
fieldListPosition	String. Indicates whether the Field List is always shown on the right (`"right"`) or in the pop-up window (`undefined`). Default value: `undefined`.
allowBrowsersCache	Boolean. Indicates whether browsers are allowed to cache the data (`true`) or not (`false`). When `allowBrowsersCache` is set to `false`, caching is not allowed, and Flexmonster appends a unique id to the data source's URL to ensure that the URL stays unique. The unique URL prevents the browser from loading the data from its cache, so the data is updated every time it is requested. Setting `allowBrowsersCache` to `true` allows caching, and the URL remains unmodified (check out an example). Default value: `false`.

How to set options

Options can be set in several ways:

The most convenient way to set options is to specify them in the report. Here is how a grid title can be added:

report: {
    dataSource: {
        filename: "https://cdn.flexmonster.com/data/data.csv"
    },    
    options: {
        grid: {
            title: "Results"
        }
    }
}

Check out a live sample on JSFiddle.

You can change options along with other report parts using API call setReport(). Options can also be changed separately via setOptions(). To see the current options use getOptions(). For example, to set the chart title:
```
flexmonster.setOptions({ chart: { title: "Chart One" } });
flexmonster.refresh(); 
```
Some options can be changed using the Toolbar. Use Options in the Toolbar to change grand totals, subtotals, and the table layout at runtime.

Default options

If an options object is not defined in the report, Flexmonster Pivot will use global options if they are defined, or defaults from the component. These options can be overridden in the report.
