Axis Titles

The axis title is a short text displayed alongside the axis. Usually, the axis title shows units of measurement for axis values, but you can put any text in it.

The axis title is configured by the title option. If you assign an object to it, specifying the text field of this object is necessary for the axis title to be displayed. Besides the object, the title option accepts a string, thus providing a shortcut for setting the axis title. Therefore, this:

jQuery
JavaScript
$(function() {
    $("#chartContainer").dxChart({
        // ...
        argumentAxis: { // or valueAxis
            title: 'Axis Title'
        }
    });
});
Angular
HTML
<dx-chart ... >
    <dxo-argument-axis
        title="Axis Title">
    </dxo-argument-axis>
</dx-chart>

is the same as this:

jQuery
JavaScript
$(function() {
    $("#chartContainer").dxChart({
        // ...
        argumentAxis: { // or valueAxis
            title: {
                text: 'Axis Title'
            }
        }
    });
});
Angular
HTML
<dx-chart ... >
    <dxo-argument-axis>
        <dxo-title text="Axis Title"></dxo-title>
    </dxo-argument-axis>
</dx-chart>

In addition to the text field, the title object may contain fields that specify the font and margin of the axis title.
