|
| MapType | The type of map to show. Possible values are 'normal', 'terrain', 'satellite', 'hybrid', or the ID of a custom map type, if any were created. | Code Block |
|---|
| mapsChart.setMapType("normal"); |
|
| ShowInfoWindow | If set to true, shows the location description in a separate window when a point marker is selected by the user. |
...

XdevMapChart mapChart= new XdevMapChart();

mapsChart.setShowInfoWindow(true); |
|
| ShowLine | If set to true, shows a Google Maps polyline through all the points. | Code Block |
|---|
| mapsChart.setShowLine(true); |
|
| ShowTooltip | If set to true, shows the location description as a tooltip when the mouse is positioned above a point marker. This option used to be called showTip up until version 45. Note that at this time, HTML is not supported, so the tooltip would show raw HTML tags. |
...
mapsChart.setShowTooltip(true); |
|
| UseMapTypeControl | Show a map type selector that enables the viewer to switch between [map, satellite, hybrid, terrain]. When useMapTypeControl is false (default) no selector is presented and the type is determined by the mapType option. |
...
mapsChart.setUseMapTypeControl(true); |
|
| ZoomLevel | An integer indicating the initial zoom level of the map, where 0 is completely zoomed out (whole world) and 19 is the maximum zoom level. (See "Zoom Levels" in the Google Maps API.) | Code Block |
|---|
| mapsChart.setZoomLevel(8); |
|
| EnableScrollWheel | If set to true, enables zooming in and out using the mouse scroll wheel. | Code Block |
|---|
| mapsChart.setEnableScrollWheel(true); |
