ILNumerics axis configuration

Question

Need your advice!

I use TickCreationFunc and LabelTransformFunc to show timeline on XAxis

Something like this:

var plotCube = new ILPlotCube(tag, true);

List<Tuple<double, string>> ticks = null;

plotCube.Axes.XAxis.Ticks.TickCreationFunc = (min, max, qty) =>
{
    ticks = AxisHelper.CreateUnixDateTicks(min, max, qty).ToList();

    return ticks.Select(x => (float)x.Item1).ToList();
};

plotCube.Axes.XAxis.Ticks.LabelTransformFunc = (ind, val) =>
{
    if (ticks != null)
        return ticks[ind].Item2;
    else
        return null;
};

plotCube.Axes.XAxis.ScaleLabel.Visible = false; //does not help

The result is quite good however I could not find a way to remove the scale label

Timeline axis

Two side questions:

1) VS shows warning 'ILNumerics.Drawing.Plotting.ILTickCollection.TickCreationFunc' is obsolete: '"Use TickCreationFuncEx instead!"'. However TickCreationFuncEx is never called.

2) Is there a way to tell ILNumerics not to abbreviate tick numbers?

Appreciate your help!

This warning is important. The scale label should go away if you use the new TickCreationFuncEx. The interface is very similar. But your function must return IEnumerable<ILTick>:

var plotCube = ilPanel1.Scene.First<ILPlotCube>();

List<Tuple<double, string>> ticks = null;

plotCube.Axes.XAxis.Ticks.TickCreationFuncEx = 
    (float min, float max, int qty, ILAxis axis, AxisScale scale) => {
        ticks = CreateUnixDateTicks(min, max, qty).ToList();

        return // return IEnumerable<ILTick> here!
};
// you should not need this
//plotCube.Axes.XAxis.ScaleLabel.Visible = false;

One cannot disable abbreviation completely. But you can specify the number of digits to show. Until 4.7 (due to a bug) you will have to use this:

ilPanel1.SceneSyncRoot.First<ILPlotCube>().Axes.XAxis.Ticks.MaxNumberDigitsShowFull = 10;

From version 4.8 you will not need SceneSyncRoot anymore and can go more straight:

ilPanel1.Scene.First<ILPlotCube>().Axes.XAxis.Ticks.MaxNumberDigitsShowFull = 10; 
// or in your case just 
plotcube.Axes.XAxis.Ticks.MaxNumberDigitsShowFull = 10;

Note: used XAxis in the code and not YAxis acc. to your example

Thanks Haymo, I tried the solution with TickCreationFuncEx. The problem there is that it never get called. Please advise what could be wrong. – irriss Apr 08 '15 at 09:41
You may have to set the deprecated version to null? Oherwise it takes precedence. – Haymo Kutschbach Apr 08 '15 at 09:47
Which version are you using? – Haymo Kutschbach Apr 08 '15 at 09:50
If I set them to null I am getting 'null reference exception'. I am using Nuget version which is 3.3.3 I believe. – irriss Apr 08 '15 at 09:59
ilPanel1.SceneSyncRoot.First().Axes.XAxis.Ticks.MaxNumberDigitsShowFull = 10; from time to time fails with exception 'sequence contains no elements' seems like a race condition ): – irriss Apr 08 '15 at 12:16
Yes, I should! Is Nuget version abandoned? Any plans to update it? – irriss Apr 08 '15 at 12:43
