Focus on items of interest

You can focus on specific chart items or categories of data by viewing distributions for a selection of your chart data. For example, in a histogram you might want to see a count of only those items that are currently selected on your chart. You can also apply filters to bar charts and histograms to look at specific areas of interest.

View selected chart items in bar charts and histograms

You can select chart items and see how selected data is distributed across any open bar charts or histograms. For example, you might select a number of transactions on your chart as a result of a Visual Search operation. By default, the distribution of these selected chart items is highlighted (brushed) back onto any open bar charts and histograms.

You can choose to turn off brushing in the Options page of the Bar Charts and Histograms pane.

View selected chart items in heat matrices

When items are selected on the chart, you can choose whether to view all chart items on a heat matrix or only the selected items. Click the required Count option at the bottom of the heat matrix.

Filtering data

You can apply (activate) filters in bar charts and histograms by clicking the bars. The resulting actions, such as whether chart items are selected and how filters are combined across the open bar charts and histograms, depend on the settings on the Options page of the Bar Charts and Histograms pane.

If the chart items that correspond to the filters are selected, by default the selection is brushed back onto any open bar charts and histograms.

You can choose what filters to apply across multiple bar charts and histograms. For example, you can select:
  • A single bar on a single bar chart or histogram. Click a bar to select it.
  • Multiple bars on a single bar chart or histogram. Press Ctrl and click to select multiple bars or Shift and click to select groups of bars. When you combine filters, this selection is treated as one filter.
  • Multiple bars across multiple bar charts and histograms. Press Ctrl and click to select multiple bars. When you combine filters, this selection is treated as multiple filters, one filter per bar chart or histogram.

To deselect all chart items, click the background of your Analyst's Notebook chart. The chart items are deselected but the filters are retained in the bar charts and histograms. To clear the filters across all of the bar charts and histograms, click Clear All Filtering at the bottom of the Bar Charts page or Histogram window.
