Current behavior
How can I display a single point in a line chart? Sorry if this isn't the correct place for this question but I can't find another one.

Expected behavior

Improve documentation with this topic.

Please tell us about your environment:

• ngx-charts version: 5.3.1

• Angular version: 4.2.5

• Browser: [all]

• Language: [TypeScript]

It seem this is a bug, because point does get rendered, but the grid for some reason is not, and since you can not display points in lines by default, you can not see it. You can put the data in activeEntries and you'll se that point is there but everything else is missing. But on the other hand, one point "line" is not a viable line, so this could potentially be expected behaviour.

I noticed that if you set autoScale=false the grid does get rendered, but it is still a problem that the point is visible only if you put it in the result+ in activeEntries and it disappears once you hover it.

I used stroke-width and stroke-linecap after the chart has been displayed. Assume the third line of your chart consists of a single data point. Then you can it display as follows:

const el = document.querySelectorAll('g.line-series path')[2];
el.setAttribute('stroke-width', '5');
el.setAttribute('stroke-linecap', 'round');
