Angular and AngularJS directives work together to indicate events on a line chart

Currently, I am creating a dashboard using AngularJS along with Angularjs-nvd3-directives, mainly focusing on line charts. I am interested in adding markers to the chart for specific events. For instance, if I have a time series data, I want to be able to draw a marker (such as a dot or a line) at a particular point in time, possibly with a customized tooltip.

Are there any methods available to accomplish this task?

Thank you in advance.

Answer №1

When it comes to personalized tooltips, one method is to insert an attribute into your chart directive:

tooltipcontent="customToolTipContent()"

Afterwards, in your controller, you can create a function that generates the HTML content:

$scope.customToolTipContent = function(){
return function(key, x, y, e, graph) {
    return  '<h1>My Unique Tooltip</h1>' +
            '<h3>' + key + '</h3>';
    }
};
