X Labels goes on top of each other when zooming in (Read 4822 times)

	Hi, I'm using a line chart which supports zoom behavior. The X-axis of the graph contains dates which are displayed as auto-scaled labels. I wish to display only 5 labels on the X axis which will not overlap. In normal mode, the graph looks ok (see attached NormalView.png file). But when I zoom in, suddenly 10 labels are being generated and goes on top of each other, creating some mess (See attached ZoomIn.png file). How can I keep the original layout of the labels (5 auto-scaled) when zooming in ? Thanks, Nir Code this.lineChart.XAxisSettings.StartDateTime = getMinDate(_xDataFieldName); this.lineChart.XAxisSettings.EndDateTime = getMaxDate(_xDataFieldName); TimeSpan span = this.lineChart.XAxisSettings.EndDateTime - this.lineChart.XAxisSettings.StartDateTime; TimeSpan quarter = new TimeSpan(span.Ticks / 4); this.lineChart.XAxisSettings.TimeSpan = quarter; this.lineChart.XAxisSettings.LabelType = MindFusion.Charting.AxisLabelType.AutoScale;

	Hi, Click the 'you have messages' link at top of the forum to open the PM page. There you can find updated build of the control that adds ZoomChanged event. You can handle it like this to keep a constant number of labels, e.g. 4: Code private void lineChart1_ZoomChanged(object sender, EventArgs e) { DateTime dt1 = lineChart1.XAxisSettings.StartDateTime; DateTime dt2 = lineChart1.XAxisSettings.EndDateTime; TimeSpan q = dt2 - dt1; TimeSpan quarter = new TimeSpan(q.Ticks / 4); lineChart1.XAxisSettings.TimeSpan = quarter; lineChart1.UpdateChart(); } I hope that helps, Stoyan
