How To Get Alternating BLUE/RED Circles In Dump1090?

The dashed lines are easy to do. I’m not sure which code you are using, but the distance circles and range plots are created in html/script.js which needs only simple changes.

For dump1090-fa, do this:

In script.js, edit the function createSiteCircleFeatures(), where the circleStyle is defined. In the “stroke:” section, add a line comprised simply of, e.g. " lineDash: [4, 4], " between the color and width lines as shown here:

    var circleStyle = new ol.style.Style({
            fill: null,
            stroke: new ol.style.Stroke({
                    color: '#000000',
                    lineDash: [4, 4],   // Add this line
                    width: 1
            })
    });

Do the same thing to the “ringStyle” definition a couple dozen lines above to change the heywhatsthat range rings to dashed lines.

Thanks toverfield for sharing the code for dashed line.
