# 13. Data selection Analytics+ offers you multiple data selection features to emphasize specific data points: * **Single click action**: Highlight any particular data point by clicking on it. * **Lasso**: You can use drag selection to analyze a specific range of information, such as the profits generated over the last quarter of the year. * **Reverse lasso**: Similar to the lasso feature, you can use drag selection to exclude a certain range of data from your analysis. For example, exclude the months with the maximum revenue and focus on the months with low performance. * **Legend-based:** Use this option to emphasize the data for a specific category. Click on the relevant category in the legend to highlight it. * **Sync highlight**: Analytics+ visuals can talk to each other - if you have multiple Analytics+ visuals on the same page, data selections in one visual will be reflected in the others as well. * **Zoom:** Drag and select any section of a chart to zoom in. Zooming can be horizontal, vertical, or in both directions. * **Drilldown for hierarchical charts:** Choose to enable cross-highlighting in other visuals, focus solely on drilldown, or combine both. * **Data selection for trellis:** Select row or column dimension categories to highlight data in other Analytics+ visuals on the same page. {% hint style="info" %} Data selection is possible only in reading mode. {% endhint %}

#### 1. Single click action: In the area chart, when we select the July data point for 2022 Actuals, notice the effect on the rest of the data points and measures.

#### 2. Lasso: We've used lasso selection to drag and highlight the data for May, June, and July. Notice how the data labels are displayed only when the data point has been selected.

#### 3. Reverse lasso We've used reverse lasso selection in this case, to highlight the data excluding the April - July range.

#### 4.Legend-based We can highlight a particular category - in this case, we've clicked on the 'Mineral Water' category in the legend to highlight it in all the trellis panels.

You can also include and exclude data categories with legend-based selection. Navigate to Legend settings > Data selection to set the type of selection.

Include/Exclude option in Legend setting

When you choose the **Include** option, Analytics+ plots only the selected data categories. The reverse happens when you choose **Exclude**. To exclude multiple categories, ctrl + click the categories.

#### 5. Sync highlight When we use the sync highlight option - the data points selected in one Analytics+ visual will be mirrored in other Analytics+ visuals and small multiple panels in the same visual. Notice how the June data point selection has been reflected in all the cards.

Analytics+ supports cross-highlighting in other visuals when you select parent or child nodes in visuals with hierarchical axis data. This is supported irrespective of whether category grouping is enabled or disabled.
