Contour

The Contour visualization method is useful when you need to understand the distribution of data on a certain area object. Physical and legal boundaries of buildings are taken into account.

Overview​

Contour

To choose a visualization method:

  1. Go to the Dashboards tab.
  2. Open the required dashboard.
  3. Open a scene using the arrows Left arrow and Right arrow. If there is only one scene in the dashboard, it opens automatically when you open the dashboard.
  4. To open the layer, click Layers icon and select the required layer.
  5. In General settings, select the Contour visualization method.
  6. Set the remaining visualization parameters if necessary.

The data is visualized on the map.

Parameters​

For the Contour visualization method, the following parameters are available:

  • Area object type: type of areal object on which the contour is built (Administrative districts, Settlements, Neighborhoods, Administrative divisions, District, Region).

  • Caption: turning on the caption on contour elements.

  • Color: selecting the color of the data display.

    • Color basis: attribute based on which the elements on the map and in the legend are colored according to the color scale. The available values ​​depend on the data in the sample. You can select only numeric attributes.

    • Color scale: set of prepared color samples.

    • Invert: select to invert the selected color scale.

    • Steps: number of steps in the color scale from 1 to 10.

    • Legend: configuring of data ranges in the legend. Ranges are calculated automatically depending on a type of scale (for Logarithmic, Linear, and Exponential types). You can also customize ranges manually by entering the required range limits or changing the order and number of ranges (Adjustable type). The specified upper (right) limit is not included in the range. The maximum number of ranges is 10.
      To change the order of ranges, hold down Move icon next to the required range and drag it. To add a range, click Plus icon. To delete a range, click Trash icon.

    • Color aggregation type: color aggregation method for one visualization element (a contour): Sum or Mean. The aggregation type is displayed in the tooltip when hovering the cursor over a contour on the map.

    • Type of scale: distribution type used to calculate data ranges in the legend:

      • Logarithmic - logarithmic distribution. Suitable for displaying data that changes over a wide range or differs by several orders of magnitude.
      • Linear - uniform distribution. Suitable for displaying values ​​of the same order.
      • Exponential - exponential distribution. Suitable if you need to highlight small values and ignore large ones, and also for displaying data that changes quickly.
      • Adjustable - manual configuring of ranges. In all ranges except the last one, the specified upper (right) limit is not included in the range.

    • Opacity: setting an opacity of the elements on the map.

  • Outline: enable to display an outline around the elements.

    • Outline color: selecting an outline color on the color palette or in HEX format.
    • Stroke width: stroke width in pixels from 1 to 25. When Height is turned on, the setting is not available.

  • Height: enable to display the data as a column chart. To enable three-dimensional display format on the map, select the 3D in the bottom-right corner of the map.

    Contour in column chart form

    • Height basis: parameter based on which the elements on the map are formed. The available values ​​depend on the data in the sample. You can select only numeric attributes.
    • Height aggregation type: height aggregation method (Sum or Mean).
    • Height scale: column height multiplier from 0.1 to 20.
