My chart is displaying data day-by-day (user and system sent SMS/Newsletters). So time part is not relevant and unnecessary. Here is an example: http://jsfiddle.net/uaxZP/1/ where time "12:00" is displayed.
How can I force Highcharts to never display the time part in a "datetime" axis?
EDIT: Highcharts will display dates w/wo times based on chart or screen size. I've updated jsfiddle removing some data and now it's displaying also time parts.
You can intercept the x-axis label function and change it's output. In my example, I've changed it to render short dates:
http://jsfiddle.net/uaxZP/3/
{ xAxis:
labels: {
formatter: function() {
return Highcharts.dateFormat("%b %e", this.value);
}
}
}
The xAxis.labels.formatter property allows control over this. You also may notice I'm using Highcharts.dateFormat, which is a utility function for rendering dates. This is not mandatory, but it's a nice built in feature. Documentation on the xAxis formatter is here:
