Hi Max,

Yup, dont know how I missed that!. Thanks a ton - it works beautifully.

You should create a single GraphicsContext for all the labels you want to rotate. You're adding a new one for each label, so each GraphicsContext is contained within another GraphicsContext, compounding the angle.

The label rotation can be done much simpler by using this:
     label.labelStyle.Orientation = TextOrientation.Custom;
     label.labelStyle.RotationAngle = 30;

Hi Max,

I tried with the following code but it didn't work as expected: it rotates the first label correctly by 30 degrees, but the second label by 60 and third by 90 and so on. I have used the Matrix object's RotateAt method. I am rotating the Y axis labels.

for (int i = 0; i < columnCount; i++)
            {
                string value = chartData.GetColumnLabel(i).ToString();

                GraphicsContext gc = new GraphicsContext();
                Matrix m = new Matrix();

                Point location = new Point((int)xAxis.Map(-.07), (int)yAxis.Map(i + 0.5));
                Text label = new Text();

                m.RotateAt(-30f, new PointF(location.X, location.Y));
                gc.Transform = m;

                //gc.SetClipBounds(e.ChartCore.GetChartLayer().GetOuterBounds());

                e.SceneGraph.Add(gc);

                SizeF labelSize = Platform.GetStringSizePixels(value.ToString(), label.labelStyle.Font);
                location.X -= (int)labelSize.Width / 2;
                location.Y -= (int)labelSize.Height;

                label.SetTextString(value.ToString());
                label.bounds = new Rectangle(location, new Size((int)labelSize.Width, (int)labelSize.Height));

                e.SceneGraph.Add(label);
            }

Please let me know what I am missing here.

Hi Max,

 Thanks a lot for the post above. It works like a charm. I could space my X and Y labels neatly in the center of my axis for my Heatmap chart.

 Could you guide me how to rotate my labels created as above, by a certain degree? I need my labels to be aligned by some degree (eg 30 degrees).

Thanka a lot.
