I’m implementing a toggle between joined and separated axes for my series and I’ve encountered a problem with my SeriesValueModifiers. The modifier seems to be connected to “DefaultAxisId”, when I have my series linked to an axis with that ID the values show up as expected. However, when I separate my series to individual axes the modifiers no longer appears.

Is it possible to collect and show all my SeriesValueModifiers on one axis (keeping the others invisible)? Or perhaps show modifiers on all the axes and stack them on top of each other, keeping labels invisible.

This is the code I’ve got right now:

Adding an axis in my constructor, this one will be used when all the series are using the same axis.

ChartYAxes.Add(new NumericAxis()
{
    Visibility = Visibility.Visible,
    AutoRange = AutoRange.Always,
});

Then I add a new axis for each series.

ChartYAxes.Add(new NumericAxis
{
    Id = tagName,
    Visibility = Visibility.Collapsed,
    AutoRange = AutoRange.Always
});

var renderableSeries = new FastLineRenderableSeries
{
    YAxisId = IsIsolatedCharts ? tagName : "DefaultAxisId"
};

Toggling between these works great, but I need the value labels for this to be useful in any way.

EDIT: In case it’s relevant, here’s the code for toggling.

private void SplitAxes()
{
    var count = Series.Count;
    for (int i = 0; i < count; i++)
    {
        var series = Series[i];
        var name = series.DataSeries.SeriesName;
        //The axes are also added to a dictionary for easy access.
        _axisDictionary[name].GrowBy = new DoubleRange(count - i - 1, i);
        series.RenderSeries.YAxisId = name;
    }
}

private void JoinAxes()
{
    foreach (var series in Series)
        series.RenderSeries.YAxisId = "DefaultAxisId";
}

Please look at screenshot. There is SeriesValueModifier with 27.68 price, but it is not fit into YAxis. Questinos:
1) How can I bind YAxis width to always fit SeriesValueModifier ?
2) How can I set font size and text formatting for value in SeriesValueModifier , not changing text on YAxis labels?
