Comment faire pivoter les étiquettes du plan de coordonnées et de l'axe Y en Java pour la visualisation des données ?

<code class="java">g2d.translate(leftStartPlotWindow, blueTop);//translate origin to bottom-left corner of blue rectangle
g2d.scale(1, -1);//invert the y-axis</code>

<code class="java">double Scalar = blueWidth/maxPlot;
ArrayList<Double> scaledDiffs = new ArrayList<>();
for(int e = 0;e<myDiffs.size();e++){scaledDiffs.add(myDiffs.get(e)*Scalar);}</code>

<code class="java">g2d.rotate(Math.toRadians(-90), 0, 0);//rotate text 90 degrees counter-clockwise
g.drawString(yString, -(height/2)-(yStrWidth/2), yStrHeight);
g2d.rotate(Math.toRadians(+90), 0, 0);//rotate text 90 degrees clockwise</code>
