SuperMap iPortal users can add layers after selecting the basemap when using the DataViz app. The administrator can control which types of layers are displayed according to requirements, and can also adjust the order of the layer type options and drag the layer types with higher usage rates to the top.

To configure the layers, log into Home>Management > App Center Management >DataViz as the administrator to enter the DataViz Setting page, click "Layer" tab.

• Display/Hide: Check or uncheck the checkbox in front of each function, and click "Save" button to take effect on DataViz.
• Drag: Drag components under the same level to adjust the order. For example, you can drag "Add by Search" to a higher position than "Add by File". After finishing adjusting, click "Save" button to take effect on DataViz.
