What’s New in 2018 Volume 2: Chart in Essential JS 2

Panning and zooming the chart can be done using mouse and touch actions on a chart area. However, if we have a scrollbar on an axis, it is easier to zoom or view data on a desktop. So, in this release, we have provided support for scrollbars in chart and they work as shown in the following.

                   

let chart: Chart = new Chart({
                 zoomSettings:
                   { 
                       enableScrollbar: true
                   }
 });

Histogram series

We have added a new series type called histogram for this release. The histogram series provides options to visualize large amounts of data that are difficult to present in a tabular or spreadsheet form.

                     

let chart: Chart = new Chart({
              series: [
                       { type: 'Histogram' }
                     ]
 });

Grouping slice in accumulation charts

Now, a set of data for accumulation charts can be grouped based on number of points. For example, when you want to show the medal details of the top 10 countries in a chart, and then put the other countries together in one category, you can use this feature. This helps you visualize data more clearly when you have a large amount of it.

let pie: AccumulationChart = new AccumulationChart({  
                groupTo: '9',
                groupMode: 'Point'
});

We hope that you will enjoy these new features in chart. These features are available for all other JS2 platforms, such as Angular, React, Vue, ASP.NET Core, and ASP.NET MVC.
