With exacticks ture and minorticks set to 0, result is infinite loop.

Couldn't confirm on chrome (because it just crashed), but on firefox, this is what I managed to get (from the compiled javasccript using map file)

function drawRadialMinorTicks(context, options) {
    var radius = radialTicksRadius(context, options);
    var s = void 0,
        range = void 0,
        angle = void 0;
    var i = 0;
    var delta = 0;
    var ratio = options.ticksAngle / (options.maxValue - options.minValue);

    context.lineWidth = SmartCanvas.pixelRatio;
    context.strokeStyle = options.colorMinorTicks;

    context.save();

    if (options.exactTicks) {
        range = options.maxValue - options.minValue;
        s = range / options.minorTicks;
        delta = options.majorTicks[0] % options.minorTicks * ratio;
    } else {
        s = options.minorTicks * (options.majorTicks.length - 1);
    }

    for (; i < s; ++i) { <-- here, s is (or should be) zero - firefox optimizes s away
        angle = options.startAngle + delta + i * (options.ticksAngle / s);

        context.rotate(drawings.radians(angle));

        context.beginPath();
        context.moveTo(0, radius);
        context.lineTo(0, radius - context.max * 0.075);
        closeStrokedPath(context);
    }
}

EDIT: Working workaround is to set minorticks to same as ~~minValue~~ -1

With exacticks ture and minorticks set to 0, result is infinite loop. #99
