var lines = {};
// Get the first line of the chart
var lineIndex = 0;
var line = coord.getLines()[lineIndex];
if(line) {
    lines[line.getId()] = line;
    // Highlight the first line of the chart
    coord.hoverItems(lines);
};
// Refresh the chart
coord.refreshView(null, false);

After executing the example the first line on the chart is highlighted.
