Implementation

  if (isLine == true) return;
  double y = 2.0;
  for (int i = 0; i < indicatorLi.length; ++i) {
    TextSpan? span =
        indicatorLi[i].drawFigure(data, fixedLength, chartColors);
    if (span == null) return;
    TextPainter tp = TextPainter(
      text: span,
      textDirection: TextDirection.ltr,
    );
    tp.layout(minWidth: 0, maxWidth: chartRect.width - chartStyle.space);

    Offset offset = Offset(x, y);

    canvas.drawRect(
      Rect.fromLTRB(
        offset.dx - 2,
        offset.dy - 2,
        tp.width + offset.dx + 2,
        tp.height + offset.dy + 2,
      ),
      Paint()..color = this.chartColors.bgColor.withAlpha(80),
    );

    tp.paint(canvas, offset);

    y = y + tp.height + 2.0; // update y
  }
