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

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1) VS shows warning 'ILNumerics.Drawing.Plotting.ILTickCollection.TickCreationFunc' is obsolete: '"Use TickCreationFuncEx instead!"'.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!

Answer 1

1. 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; 
   

2. 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
