The specifications may change without notice. {% endhint %} The Cross Filter feature allows you to synchronize the display targets of multiple charts when legends or axes are filtered on a specific chart. Filtering is performed on data loaded in the frontend, so changing filters does not trigger additional job execution. ## Behavior * Legends and axes selection status is synchronized across configured charts * When a legend on a chart is selected: Only data for the selected legends is displayed * When hovering over chart content: Highlighting of the hovered legend is synchronized * When selecting a range on an axis: Only data within the selected range is displayed ## Configuration * Select Cross Filter from the menu that appears in the top-right corner when hovering over a chart on the Grid Page * Set a `Key` * Set the same `Key` for charts that you want to synchronize with the same value * Depending on the selected chart, you can set `Keys` for both "Axis" and "Legend" * For table charts, set a `Key` for each column you want to target ## Specifications * Supported Charts * XY Chart * XYZ Chart * Pie Chart * Funnel Chart * Table Chart * Selection states from other charts are reflected in table charts, but filtering content from table charts is not reflected in other charts * Data Filtering Scope * Filtering is performed on data loaded in the frontend * SQL is not re-executed, so filtering data by time period on an XY chart axis cannot be reflected in pie chart aggregations * Legend Filtering * Filtering is performed based on the "string or numeric" values of the selected legend names * Axis Filtering * Range filtering is performed based on the "string or numeric" lower and upper bounds of the selected axis ## Notes * Legend → Axis Coordination * Data display targets for axes are specified by range * Therefore, when multiple legends are selected on the legend side, not only the selected legends but also targets included in the range of the selected legends will be displayed * Axis → Axis Coordination * When axes are set as strings, range specification is affected by display order, so if display orders are different, they may not coordinate correctly --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://docs.codatum.com/data-exploration/notebook/grid-page/cross-filter.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
