Map chart with custom background image

Dear all,

Our aim is setting some marker with value on a background image. 
When we use your sample https://aspnetmvc.syncfusion.com/Maps/Seatbooking#/material to try
and insert a image as background. We found that the image can't be shown in div element.

Please help and advance, thx.

Hi Kenneth, 
 
Greetings from Syncfusion. We have analyzed your query. In the seating arrangement sample, we have used the customized shapes. We have online sample in which we have added images using the marker template in the below. 
 
 
For more information on marker, kindly find the help document. 
 
Since we are not clear with your exact requirement where you need to add background image, kindly share some screenshots with respect to your requirement or provide more information on your query. This will be much helpful in further analysis and provide you the solution sooner. 
 
Thanks, 
Dharani.

Dear Dharani,

We have use your reference to create with the following code

@using Syncfusion.EJ2
@using Syncfusion.EJ2.Maps
    <div class="col-lg-9 control-section">
        <div style="border: 3px solid #b6ff00;width: 600px;height: 400px;margin:auto;border-radius:5px;">
            <div style="text-align:center">
                <div id="container"></div>
                @Html.EJS().Maps("container").Load("mapsLoad").Layers(layer =>
           {
               layer
               .LayerType(Syncfusion.EJ2.Maps.ShapeLayerType.OSM).UrlTemplate("/Map/Sample_Floorplan.jpg"
               ).MarkerSettings(ViewBag.markerSettings).ShapeSettings(new MapsShapeSettings { Fill = "#C3E6ED" }
                   ).SelectionSettings(new MapsSelectionSettings{ Enable = true, Opacity = 1, EnableMultiSelect = true }
                   ).Add();
           }).Render()
            </div>

        </div>
    </div>
    <style>


        #control-container {
            padding: 0px !important;
        }

        #seat-parent {
            text-align: center;
            cursor: pointer;
        }

        #selectedseats {
            padding: 10px;
        }

        #selectedseats, #seat-info {
            font-size: 14px;
        }

        #clear-btn {
            padding: 10px;
            border: 2px solid rgb(241, 235, 247);
            border-radius: 8px;
            background: rgb(246, 245, 248);
            color: black;
            font-size: 14px;
        }

        .seats {
            padding-top: 15px;
            font-weight: bold;
        }
    </style>

Hi Kenneth, 

We have analyzed your query. You can the render the custom shapes for using the geometry type as ‘normal’ and using the custom coordinates as desired you want. And also place the marker for custom shapes by passing the coordinates into the marker latitude and longitude properties. You can render the floor plan map by using custom coordinates as desired you want. We have prepared a custom shape sample and place the marker.   

Please find the below code snippet to achieve this custom shape and marker, 
@Html.EJS().Maps("maps").Layers(m => 
   { 
       m.GeometryType(GeometryType.Normal).MarkerSettings(ms => 
       { 
           ms.Visible(true).DataSource(ViewBag.markerData).Add(); 
       }).ShapeData(ViewBag.mapsData).Add(); 
   }).Render() 
 
 
busSheetData.json: 
 
{ "type": "FeatureCollection", "features": [ 
            { "type": "Feature", "geometry": { "type": "MultiPolygon", "coordinates": [[[[0, 0], [0, 20], [20, 20], [20, 0], [0, 0]]], [[[0, 22], [0, 27], [20, 27], [20, 22], [0, 22]]]] }, "properties": { "seatno": 19, "fill": "gray" } }, 
           . . . 
           . . . Add more data’s 
       ] } 
 
MarkerData: 
List<MarkerData> data = new List<MarkerData> 
            { 
                new MarkerData  { latitude= 94, longitude= 0, name= "Bottom left corner" }, 
                . . .  
                . . . Add more data’s 
           }; 
            ViewBag.markerData = data; 

Screenshot: 
 

Sample for your reference, can be found from below link, 

Kindly revert us, if you have any concerns. 

Regards, 
Baby.

Dear Baby,

Could we use jpg or png file as background rather that using custom coordinates ?
Please advance, thx.

Hi Kenneth, 
 
We have analyzed your query. As of now, we are not having support for setting background image for maps. But as a workaround, we have achieved your requirement in the maps loaded event. And you need to add some dummy data for the maps. In the loaded event, we have added image element as a first child for the maps SVG element.  
Please find the below code snippet to achieve this requirement, 
 
  @Html.EJS().Maps("maps").Loaded("loaded").Render() 
 
var loaded = function (args) { 
        var svgNS = "http://www.w3.org/2000/svg";   
        var parentSvg = document.getElementById(args.maps.element.id + '_svg'); 
        if (!(parentSvg.firstChild).querySelector('image')) { 
            var imgElement = document.createElementNS(svgNS, 'image'); 
           //Other configurations 
            imgElement.setAttributeNS(null, "rel='nofollow' href", "https://i.imgur.com/klEEdXI.jpg"); 
            parentSvg.insertBefore(imgElement, parentSvg.firstChild); 
        }         
        setTimeout(function () { 
            var BorderEle = document.getElementById(args.maps.element.id + '_MapBorder'); 
            BorderEle.setAttribute('fill', 'transparent'); 
        }, 100) 
    }

Dharani.

Dear Dharani,

Thank for Info! We had successful to use your coding for display the background image with the map feature.
But we want more information to display when mouse over the marker, such as name & In / Out Count.

The following are our coding

chtml
<div id="template" style="display:none">
    <div class="toolback">
        <div class="listing2">
            <center>
                ${name} , ${InCount}
            </center>
        </div>
      </div>

</div>

<div class="row">
    <div id="maps" stlye="display: block">
        @Html.EJS().Maps("maps").Loaded("loaded").Layers(m =>
   {
       m.GeometryType(GeometryType.Normal).MarkerSettings(
       ms =>
       {
           ms.Visible(true).Shape(MarkerType.Circle).Height(15).Width(15).TooltipSettings(ts => ts.Visible(true).ValuePath("camInfo").Template("template")).DataSource(ViewBag.markerdata).Add();
       }
       ).ShapeData(ViewBag.mapsData).Add();
   }
        ).MapsArea(ma =>ma.Background("transparent")).Render()
    </div>
</div>

controllor
public ActionResult Test()
{
            List<MarkerData> data = new List<MarkerData>
                {
                    new MarkerData  {
                        latitude = 94,
                        longitude = 0,
                        canInfo = new camInfo{
                        name = "10.99.33.100",
                        InCount = 400,
                        OutCount = 534
                    }
                    },
                    new MarkerData { latitude=47, longitude=20,
                        canInfo = new camInfo{
                            name = "10.99.33.101",
                            InCount = 4534,
                            OutCount = 934
                        }
                        },
                    new MarkerData { latitude= 20, longitude= 20,
                                                 canInfo = new camInfo{
                           name = "10.99.33.102",
                            InCount = 412,
                            OutCount = 234
                    } }
                };

            ViewBag.markerData = data;
            return View();
}

Please advance & thx.

Hi Kenneth, 
 
Thanks for your information. We have analyzed your query and from the provided code snippet we found that you have skipped to use ‘#’ symbol in the template. So, the template is not loaded. Find the code snippet to achieve this. 
 
 
@Html.EJS().Maps("maps").Layers(m =>{ 
       m.MarkerSettings( ms => { 
         ms.TooltipSettings(ts => ts.Template("#template")).Add(); 
     }) 
 }).Render()

Thanks, 
Dharani.

Dear Dharani,

Thank for your sharing, could we change the dot color on the map base on markerdata value? such as inCount > 1000, display red dot  otherwise display green dot.
Please advance, thx.

Hi Kenneth, 

Thanks for your update. 

We have analyzed your query. You can customize the marker fill in the markerRendering event. Please find the below code snippet to achieve this requirement, 

Controller.cs 
  
List<MarkerData> data = new List<MarkerData> 
            { 
                new MarkerData  { latitude= 94, longitude= 0, value = 900 }, 
                new MarkerData { latitude=47, longitude=20, value= 2200 }, 
                new MarkerData { latitude= 20, longitude= 20, value= 3000 } 
            }; 
            ViewBag.markerData = data; 

.cshtml: 
  
@Html.EJS().Maps("maps").MarkerRendering("markerRendering").Layers(m => 
   { 
       m.GeometryType(GeometryType.Normal).MarkerSettings(ms =>       { 
ms.Visible(true).Shape(MarkerType.Circle).Height(15).Width(15).TooltipSettings(ts => ts.Visible(true).ValuePath("value")).DataSource(ViewBag.markerData).Add(); 
       }).ShapeData(ViewBag.mapsData).Add(); 
   } 
       ).MapsArea(ma =>ma.Background("transparent")).Render() 

var markerRendering = function (args) { 
        if (args.data.value > 1000) { 
            args.fill = 'red'; 
        } else { 
            args.fill = 'green'; 
        } 
    }

Dear Baby,

Thank for your sharing. Could we add the click event on each of marker also ?
Please advance & thank.

Hi Kenneth, 

Thanks for your update. 

We have analyzed your query. We are having markerClick event for markers click. We have prepared a maps sample with a marker click event. In that sample, we have shown an alert box for the marker click. Please find the below code snippet to achieve this requirement, 

<div id="maps" stlye="display: block"> 
        @Html.EJS().Maps("maps").Loaded("loaded").MarkerClick("markerClick").Render() 
    </div> 
 
 
var markerClick = function (args) { 
        alert("Marker clicked"); 
    } 

Screenshot: 
 


Kindly revert us, if you have any other concerns. 

Regards, 
Baby.
