Current behavior there is no time series (historical) bar chart component the "ngx-charts-timeline-filter-bar-chart" can't deal with non-continues times data https://swimlane.github.io/ngx-charts/#/ngx-charts/timeline-filter-bar-chart-demo also I can set null value as results.push({ name: new Date(date), value: null }); when there is no data. would that be performance hit when the whole history data is scattered that only a small portion of time point have data ?

Expected behavior provide time series (historical) bar chart component

Reproduction of the problem

What is the motivation / use case for changing the behavior? It is a common feature with java-script chart library, for example: http://plnkr.co/edit/w9LnjVxWFCSkU3Vxs7pU?p=preview
