The Map chart is used to position data in a geographical context. Multiple layers are included to cover various information. The users can specify which layer to be marked as an interactive layer as it is the only layer wherein items can be marked.

Best Situations to Use a Map chart

Map Chart with SVG Type

Map Chart with Leaflet Type

Leaflet Auto Zoom

The user can use the Auto-zoom functionality to cover all the markers in the map component. This functionality is available in zoom-in map (Leaflet) based on number of markers and their placed positions so that all markers must be visible at that zoom-in level.

Leaflet Trip/Trail – Property - Line Type

The Line Type property is provided in the General tab for the Trip and Trail Geometry type Leaflet maps. The user can show Trip/ Trail map lines in any of the following three categories:

  1. Straight Line

  2. Dotted Line

  3. Dashed Line

Leaflet Trip Type Straight Line Map

Leaflet Trip Type with Dash Line Map

Leaflet Trip Type Dotted Line Map

Please Note:

  • At present, this feature has been provided to the Leaflet Trip/Trail Geometry Type maps only.

  • The width of line or dot is fixed for all the supported line types.

Leaflet support for the Glyph and Maki Marker Icons

The Glyph and Maki marker icons are supported in the Leaflet map type chart. The user needs to set m_svgicons variable to false using the SDK script. The following three types of icons are supported in the Leaflet map with the Trip Geometry Type:1. For Marker with custom icons we use Maki Icons https://labs.mapbox.com/maki-icons/​2. For custom markers we can use Glyph Icons https://getbootstrap.com/docs/3.3/components/#glyphicons​3. For custom markers we can also use font icons like bd-filter, bd-*Please Note:

  • Currently we provide support for Leaflet Trip Type Non SVG.

  • To achieve these icons, we have to set m_svgicons variable to false using the SDK script.

​A sample script with m_svgicons variable to false is given below:

sdk.getWidget( 'map2').m_drawTripPath = true; // for linesdk.getWidget( 'map2').m_svgicons = false;var comp = sdk.getWidget( 'map2' );comp.m_mapoptions.center = [44.91209,8.60492];comp.m_mapoptions.zoom =50;//for changing start & end markers & its colorcomp.m_markericon.icon="bd-car";comp.m_startcolor = "#21f110";comp.m_endcolor = "#12e925";//for changing path colorcomp.m_pathcolor = "#bf404d";//for changing path markers & its colorcomp.m_pathicon.icon= "bd-location";comp.m_pathicon.color="#d62728";​

Display Circle Data Points in the Leaflet charts

The Circle data points in Leaflet charts likely refer to markers that are displayed on the map in the shape of a circle. These markers can be used to indicate a specific location or set of coordinates on the map, and can be customized in terms of color, size, and other visual properties. BDB Designer draws circles considering the first data point as center, provided with an option to configure at which data point circle should render it.

Steps to Configure Circle Data Points & Show Marker through Script

  • Add a variable to control geometry type as circle.

sdk.getWidget(‘map1).m_geometrytype = “circle”

  • Draw marker for other data points when Geometry type is circle.

sdk.getWidget(‘map1’).m_showmarker = trueva

Configure Circle as a data point.

  • By default, it draws a circle considering the first point.

  • The user can control the circle data point through script.

sdk.getWidget(‘map1’).m_circleindex = 21;

Series Indicator

The Map chart supports Series Color based on the conditions.

  • Open the Dataset properties for the Map component.

  • Select a Series.

  • Open the Indicator tab.

  • Click the Add New Condition icon.

  • The Conditional Color dialog box opens for the selected series field.

  • Select one option out of Fixed Value Comparison or SVG.

  • Complete the required configuration.

  • Click the Create option.

  • Open the preview of the Map chart to view the conditional color for the set value.

Sample Data

Download the given sample data and map it as mentioned below to plot your Map chart.
