How to add functionality so we can change Label Rotation Angle for Y-Axis similar to X-Axis

[gitam2869]

I am able to extend YAxisRenderer.java and I and tried following:

**protected void drawYLabels(Canvas c, float fixedPosition, float[] positions, float offset) { super.drawYLabels(c, fixedPosition, positions, offset);

    final int from = mYAxis.isDrawBottomYLabelEntryEnabled() ? 0 : 1;
    final int to = mYAxis.isDrawTopYLabelEntryEnabled()
            ? mYAxis.mEntryCount
            : (mYAxis.mEntryCount - 1);

    // draw
    for (int i = from; i < 1; i++) {

        String text = mYAxis.getFormattedLabel(i);

        c.rotate(15f);

        c.drawText(text, fixedPosition, positions[i * 2 + 1] + offset, mAxisLabelPaint);
    }
}**

But Unable to achieve expected output. Please give me some idea. Thanks in advance.

the same text need more space after rotate.maybe you can reference Utils class drawXAxisValue mothod.

key code

if (angleDegrees != 0.f) {

            // Move the text drawing rect in a way that it always rotates around its center
            drawOffsetX -= mDrawTextRectBuffer.width() * 0.5f;
            drawOffsetY -= lineHeight * 0.5f;

            float translateX = x;
            float translateY = y;

            // Move the "outer" rect relative to the anchor, assuming its centered
            if (anchor.x != 0.5f || anchor.y != 0.5f) {
                final FSize rotatedSize = getSizeOfRotatedRectangleByDegrees(
                        mDrawTextRectBuffer.width(),
                        lineHeight,
                        angleDegrees);

                translateX -= rotatedSize.width * (anchor.x - 0.5f);
                translateY -= rotatedSize.height * (anchor.y - 0.5f);
                FSize.recycleInstance(rotatedSize);
            }

            c.save();
            c.translate(translateX, translateY);
            c.rotate(angleDegrees);

            c.drawText(text, drawOffsetX, drawOffsetY, paint);

            c.restore();
        } else {
            if (anchor.x != 0.f || anchor.y != 0.f) {

                drawOffsetX -= mDrawTextRectBuffer.width() * anchor.x;
                drawOffsetY -= lineHeight * anchor.y;
            }

            drawOffsetX += x;
            drawOffsetY += y;

            c.drawText(text, drawOffsetX, drawOffsetY, paint);
        }
