how can i add in highcharts a different dashStyle just for a part of the graph

Question

At the last two days i want to indicate that i am missing some data, and i'd want it to show a straight dashed line on the same graph. can i change the dashStyle only for parts of the graph?

Answer 1

No it is not possible, you need two series, first line and second with dashed style.

Answer 2

You can apply 'zones' to a series: http://api.highcharts.com/highcharts/plotOptions.series.zones Just use the dashStyle option like in this example http://jsfiddle.net/gh/get/library/pure/highcharts/highcharts/tree/master/samples/highcharts/series/color-zones-dashstyle-dot/

 zones: [{
        value: 8
    }, {
        dashStyle: 'dot'
    }]
