Hello Pasi,

how can I make the chart automatically adjust to the height of the Legend box?

You can utilize LegendBox.GetRenderedRect() which tells the screen coordinates of the LegendBox. Adjust margins based on that.

In chart initialization, set chart.AxisLayout.AutoAdjustMargins = false.

In LegendBox.MovedByMouse and chart.SizeChanged event handler, use the following approach to adjust the margins. Here, top margin is adjusted based on legend box, others are at their fixed values.

Rectangle r = m_chart.ViewXY.LegendBox.GetRenderedRect();
m_chart.ViewXY.Margins = new Padding(100, r.Top + r.Height, 50, 30);
