General - TreeMap

The graph function of DataChain is accessible from the HandleData module. handleData-color

The number of graphics that can be created is not limited.

This function is used to present data sources in the form of a graph of type . Several types of graphs are available.

Like the other components, the TreeMap can be integrated into Tableaux de Bords.

A Treemap, (box map or proportional map) is a data visualization method. It allows you to view the information hierarchically in a tree structure. The data is organized in levels (here 3 possible levels). Each level is represented by a rectangle whose size represents the corresponding quantity.

Creation of a TreeMap type graph

List of existing graphics

The creation of a TreeMap chart (like all operations on presentations) is performed from the HandleData module. Logo HandleData

Step 1

  • Access HandleData module Logo HandleData

  • 1 Choose, in the left menu HandleData, the option Graphic associated with the icon. chart-line

Access to the list of graphics

Metadata

2nd step

  • 2 Click on the button New

  • A screen allows you to choose the type of graph you want. To create a TreeMap type graphic, choose the icon treemap.svg

  • Each graph has a metadata panel. Entering a label is required.

Metadata of a new graphic

Optional input areas allow for more description. An icon can thus be assigned to the metadata of a chart.

  • information It is advisable to save the metadata as soon as you enter it. Use the button Save button located in the right part of the top banner of the screen.

Tab - Data Sources

Step 3

  • At least one data source is required to create a chart. Use the btn-ajouter-source.svg[add a source] icon to access the list of available sources (cf DataBlocks documentation).

  • information Proposed sources are related to current user’s rights

  • information It is possible to integrate, on the fly, a file with a separator. To do this, use the Rapid Integration function via the icon Rapid integration icon located in the top banner of the HandleData application.

1 Sources are powered by DataBlocks. It is possible, at the level of each source, to carry out operations making it possible to adapt, for a presentation, the blocks of original data by clicking on the icon Icone edit

2 Displays a succession of operations such as generation of formulas, filters, aggregations, sorting and modification of labels and types are available.
The Dates display format must be defined in the third step to be visible in the Viewer.

Source Operations Handle

Step 4

The list of available sources is presented in the form of a table. In the proposed list, choose one (or more) sources then double-click on the line or use the button Validate to assign the source to the graphic.

Choice of sources

1 Refreshes the list of available sources

2 Validates source assignment. It is necessary, before this operation, to choose a source by selecting arow in the sources table.

3 Return to the list of sources assigned to the graphic.

Warning Unlike TimeLines or Maps, only one source can be affected

Step 4 Bis (optional)

  • If necessary, the user can make changes to the chosen sources:

    • Added formulas creating new values

    • Generation of filters

    • Sorts

    • Aggregations

  • To do this, select one of the sources assigned to the current graph. Use the edit icon located at the end of the line (or click on the source label). Make the necessary changes. Save the changes using the Validate button then the Back button icon to return to the list of sources for the current graph.
