Any plans for extended Spline Area charts?

[Cristian Scutaru]

I'm thinking at Range Spline Area, Stacked Spline Area, and Stacked 100% Spline Area. 

They should be easily implemented with combinations between Range or Stacked charts and the Spline Area. 

In the meantime, is there any way we could emulate these charts with your current implementation?

Thanks,

Hi Cristian, 

Thanks for contacting Syncfusion support. 

As we don’t have support to render stacking spline area chart and 100% stacking spline area, we have added it to our feature request list. And for better follow up we have created branch incident under your account. Kindly follow up with the branch incident for further details. 

Also as per you request, we have created workaround samples to achieve your requirement by using load event of the chart. Find the samples below. 

Stacking spline area: http://jsplayground.syncfusion.com/pksmctlg  

100% spline area: http://jsplayground.syncfusion.com/5cjendsp  

Code snippet for Stacking spline area:  

[JS] 

$("#container").ejChart( 

            { 

              //... 

              load:"chartLoad", 

  }); 

 

function chartLoad(sender) { 

            for (var i = 1; i < sender.model.series.length; i++) { 

                for (var j = 0; j < sender.model.series[i].points.length; j++) { 

                    var currentPoint = sender.model.series[i].points[j].y; 

                    previousPoint = sender.model.series[i - 1].points[j].y; 

                    sender.model.series[i].points[j].y = currentPoint + previousPoint; 

                } 

            } 

            sender.model.series.reverse(); 

        }

Code snippet for 100% stacking spline area: 

[JS] 

$("#container").ejChart( 

            { 

              //... 

              load:"chartLoad", 

  }); 

function chartLoad(sender) { 

            var series = sender.model.series; 

            var maxPoints = 0; 

            // find the maximum points count 

            for (var i = 0; i < series.length; i++) { 

                maxPoints = (series[i].points.length > maxPoints) ? series[i].points.length : maxPoints; 

            } 

 

            for (var j = 0; j < maxPoints; j++) { 

                currentPointIndex = j; 

                // total of all points 

                var maxValue = 0; 

                for (var l = 0; l < series.length; l++) { 

                    maxValue += series[l].points[currentPointIndex].y; 

               } 

                // getting percentage value 

                var value = 0; 

                for (var m = 0; m < series.length; m++) { 

                    if (!ej.util.isNullOrUndefined(series[m].points[currentPointIndex])) 

                        value += (series[m].points[currentPointIndex].y / maxValue) * 100; 

                    series[m].points[currentPointIndex].y = value; 

                } 

            } 

            sender.model.series.reverse(); 

        }

Thanks,

Thanks a lot, Dharani, it looks great. 

The only thing left to do was to adjust a bit the series line and back colors, because of the reversal. 

Cheers,

Cristian
