Usage

From source file:org.stockchart.core.LegendItem.java

protected void innerDraw(Canvas c, CustomObjects customObjects) {
    c.getClipBounds(this.TempRect());

    float halfHeight = this.TempRect().height() / 2f;

    drawMarker(c, halfHeight, halfHeight, fMarkerSize / 2);

    fAppearance.applyText(this.Paint());

    SizeF sz = fAppearance.measureTextSize(fText, this.Paint(), false);

    c.drawText(fText, fMarkerSize + getOutlineIssues(), halfHeight + sz.height / 2f, this.Paint());
