7.4. Visualization

With Tale of Data you can create all sorts of chart just using drag and drop.

Caution

The charts let you view just the sample data you are manipulating in your flow, making it easier to identify quality problems in the data. Although sample size can be increased by adjusting the Record limit setting for flow source nodes, the functionality was not originally designed to allow data to be viewed across all datasets.

Tip

You can continue using the Filters and Facets tab in Visualization to filter new charts immediately they have been created.

  • Visualization image385.

  • Selection of the type of chart image386 you want to create (vertical/ horizontal bar, pie, donut, grouped vertical/horizontal bar, data table, map). Depending on the type of chart selected, the zone image387 will show 2 or 3 drop areas (drag and drop).

  • Zone listing the dimensions[5] available image388. Drag and drop a dimension to the first area (called Déposer la dimension pour la catégorie) in the drop zone (= zone image389). If the drop zone contains an area called Déposer la dimension pour la sous-catégorie, make a second drag and drop of another dimension to that area.

  • Zone listing available measurements[6] image390. Drag and drop a measurement to the last area in the drop zone (called Drop the measurement).

  • When all the areas in the drop zone have been filled (= zone image391), your view will display.

  • Report/chart sorting image392 by measurement (ascending/descending) or category (ascending/descending).

  • Exploded view image393 (split) of the report/chart into several sub-reports, obtained by selecting a split dimension.

  • You can select the number of columns image394 to be filled with sub-reports after you have exploded your report/chart..

  • Hide the drop zone to leave more space for your charts image395.

image396

  • You can select the max number of different values image397 you want to display for a dimension. This functionality is generally used together with sorting of measurements. For example, the figure above shows how to display for each sub-report just the 5 US states that have the highest sales (amount).

  • Click here to export image398 the chart to vector or image format (so that you can e.g. include it in a presentation).

By dragging and dropping a date as the dimension of a report, you automatically discretize the dates (auto-binning).

You can also select an interval (year, quarter, month, week, day, hour or even minute):

Automatic geographic place recognition lets you create maps using the same drag and drop method:
