Add TransformedAxis and TransformedAxes

[alanocallaghan]

Supply a basic abstract class to clarify which methods need to be overridden to create a functional class. Do not provide a default implementation but do provide two concrete classes for common options via static method.

I haven't run it, but I like the look of it. Added some comments, will actually try using it at some point.

Good yeah, I tested it on scatter plots but not yet histograms. I may still tweak the axis limits

[alanocallaghan]

I seem to have messed this up somewhere along the line

Slightly artificial example:

import javafx.application.Platform
import javafx.scene.chart.ScatterChart
import javafx.collections.FXCollections
import javafx.scene.chart.XYChart;
import javafx.scene.chart.NumberAxis;
import javafx.stage.Stage;
import javafx.scene.Scene

import qupath.fx.charts.TransformedAxes
import qupath.lib.objects.PathObjectTools


var chart = new ScatterChart<>(TransformedAxes.log1p2(), TransformedAxes.log1p10())
var cells = getCellObjects()

var xFun = {p -> PathObjectTools.getROI(p, true).getCentroidX()}
var yFun = {p -> PathObjectTools.getROI(p, true).getCentroidY()}

var data = cells.stream()
        .map(p -> new XYChart.Data<>(xFun(p), yFun(p), p))
        .toList();
var series = FXCollections.observableArrayList()
series.add(new XYChart.Series<>("Series A", FXCollections.observableArrayList(data)));

chart.setData(series)


Platform.runLater( {
    var stage = new Stage()
    stage.setScene(new Scene(chart))
    stage.show()
})
