Demand and Supply Distribution

On this page you can see how your demand and/or supply is distributed over your customer/supplier locations.

The Demand/Supply Distribution Map represents all locations to consider in your dataset. Use the widgets to change settings.

In the action menu widget-actions for the map, you can find the following options:

  • Reset Map Area - Reset the visible area of the map so that all locations are visible.
  • Show All Resources - Toggles between showing existing resources on the map and hiding them. Fixed resource locations are always displayed. If your dataset does not contain any resources, the Show All Resources option is inactive.

When you are ready to calculate Center of Gravity, click the buttons at the bottom of the page:

Select Demand/Supply input data

On the Demand and Supply Distribution page you can select what information you want to see and take into account when doing the Center of Gravity calculations. In the Select Demand/Supply Input Data selection widget, you can select whether to consider demand/supply. Depending on your data configuration, you can select from the following:

  • Locations only - Demand and supply values are not considered. All locations pull with equal force on the Center of Gravity.
  • Demand only - Supply locations are not considered. Demand locations with a high demand pull harder on the Center of Gravity than locations with low demand.
  • Supply only - Demand locations are not considered. Supply locations with a high supply pull harder on the Center of Gravity than locations with low supply.
  • Demand and Supply - Both demand and the supply locations (if you have any) are considered in proportion to their loads. Locations with a high demand/supply pull harder on the Center of Gravity than locations with low demand/supply.


When demand and/or supply data is considered, the Configuration widget appears. You can switch on Show Demand/Supply in Map. The color and the size of nodes represent the amount of demand/supply load for each location.

  • Red - high load
  • Orange - medium load
  • Yellow - small load

These labels are relative. Center of Gravity divides the range of all loads being considered into three equal parts.


When demand and/or supply data is considered, the Totals widget appears. You can see the total amount of demand and supply that is taken into account, based on what has been selected (demand/supply/products).

Decrease/increase nodes

When the demand/supply is shown in the map, the Decrease/Increase Nodes widget appears. Use the slider to decrease/increase the node size factor so that the visualization is useful based on your data. This is helpful, e.g., when high demand/supply nodes overlap, or several small nodes are difficult to see on the map.


In the Legend widget you can see what the colors of the nodes on the map mean. Supply and Demand locations have different colors. Centers of Gravity have a different color (but these do not appear on the map until they have been calculated).

Select Products

In the Select Products widget, select products or product groups to consider in Center of Gravity calculations using the checkboxes.
