Angular Chart - Strips

A strip is a colored piece of the chart's background that highlights a range of values. Strips allow a viewer to see whether a certain series point falls in or out of a range.

DevExtreme HTML5 JavaScript Charts Strips

To configure the strips, declare the strips array in the argumentAxis or valueAxis object. This array should contain objects, and each of them configures a single strip. To limit a strip, set its startValue and endValue properties. You may set only one of them, in which case the strip will not have a limit at one end. Note that setting the color property is also necessary for a strip to be displayed.

JavaScript
$(function() {
    $("#chartContainer").dxChart({
        // ...
        argumentAxis: {
            strips: [
                { startValue: 100, endValue: 150, color: 'yellow' },
                { startValue: 50, endValue: 70, color: 'orange' }
            ]
        },
        valueAxis: {
            strips: [
                { startValue: 40, endValue: 50, color: 'blue' },
                // This strip extends from 70 up to the chart's end
                { startValue: 70, color: 'red' }
            ]
        }
    });

If several strips should have a uniform style, you can specify it using one of the following objects.

  • argumentAxis.stripStyle
    Style for strips belonging to the argument axis.

  • valueAxis.stripStyle
    Style for strips belonging to the value axis.

  • commonAxisSettings.stripStyle
    Style for all strips in the Chart.

Note that individual settings override axis-specific settings which, in turn, override common settings.
