I also found this to be the case. The instructions seem clear but even with a confirmed internet connection, the licenses remain unreleased. It took a little time but I was able to resolve it through the SoftwareFX security department. (See post http://community.softwarefx.com/forums/t/12364.aspx for license check/compliance links).

Yes, that's I believe so, although I'm new to this. I started with the RealTime example project supplied, then replaced the tick event with a sandbox method as follows: private void timer1_Tick(object sender, EventArgs e){ cumulativePointCount++; if (pointCount < nTotalPoints) pointCount++; else { if (pointCount == nTotalPoints) { if (radioButton4.Checked) chart1.RealTime.Mode = RealTimeMode.Scroll; pointCount++; } } //Insert some predictable 'ramp' data chart1.RealTime.BeginAddData(1, RealTimeAction.Append); chart1.Data[0, 0] = (cumulativePointCount % 25) / 100.0 + 2.1; chart1.RealTime.EndAddData(radioButton4.Checked, true); //Attempt to use through X series var points = chart1.Data.Points; // This returns 181 var hasData = chart1.Data.X.HasData; // This always return false var exceptionThrown = chart1.Data.X[0, 0]; // This always throws ArgumentOutOfRangeException}

Thanks Andre, It is a real time chart and functions have previously been added to maintain, clear and redraw all the lines after each refresh/scroll although I appreciate that this impacts performance quite a lot. While I can create AnnotationArrows at the relevant position using annotation.Attach(dx, dy), I need to retrieve the value for dx. The sample application (X-Axis is date) iterates over the Data.X series and returns the first matching value. However, it appears that in my RealTime chart, the Data.X series is empty (Data.X.HasData returns false, Data.X[0] etc. throws Exception). Is there another way to get the X-Axis point from the actual X-values

I have a chart with many CustomGridLines to indicate the position of specific identified events. We also have a number of Panes to indicate different data sources. I would like to identify the event using a colored vertical line on a single pane (not through all the panes). Is this possible? If not, is there another means to achieve the same effect?
