JavaScript/jQuery Charts - Resolve Label Overlap

In this demo, argument axis labels overlap due to their length.

To specify the overlapping behavior, you can use one of the following label.overlappingBehavior modes:

none
Leaves axis labels overlapped.
hide
Hides certain axis labels and leaves more space for the others.
rotate
Rotates axis labels at the angle specified by the rotationAngle property.
stagger
Arranges axis labels into two staggered rows. Use the staggeringSpacing property to specify an empty space between rows.

#chart { height: 330px; max-width: 900px; margin: auto; } .options { padding: 20px; margin-top: 20px; background-color: rgba(191, 191, 191, 0.15); } .caption { font-weight: 500; font-size: 18px; } .option { margin-top: 10px; } .option > span { position: relative; top: 2px; margin-right: 10px; } .option > .dx-widget { display: inline-block; vertical-align: middle; }

const overlappingModes = ['stagger', 'rotate', 'hide', 'none']; const population = [ { country: 'China', val: 1382500000 }, { country: 'India', val: 1314300000 }, { country: 'United States', val: 324789000 }, { country: 'Indonesia', val: 261600000 }, { country: 'Brazil', val: 207332000 }, { country: 'Pakistan', val: 196865000 }, { country: 'Nigeria', val: 188500000 }, { country: 'Bangladesh', val: 162240000 }, { country: 'Russia', val: 146400000 }, { country: 'Japan', val: 126760000 }, { country: 'Mexico', val: 122273000 }, { country: 'Ethiopia', val: 104345000 }, { country: 'Philippines', val: 103906000 }, { country: 'Egypt', val: 92847800 }, ];

All of the values above can be applied to a horizontal axis, but only none and hide can be specified for a vertical axis.
