I have a fastline series and add a point to x=1; y=10 and x=4; y=13. Now I nee do know the value of Y at x=2. Is there a Method that I can call?

Is it possible to draw a highlow series where the high and low graphs are the result of the smoothing function? Can I apply the smooting function to a highlow series (both, high AND low)?

I need to get all the series points in a double array to save them in a database, but double myVals[] = highlow.HighValues.Value; does not work properly, because the Value[] array of the series always seems to be some elements longer than I would expect from Series.Count. If I have to do the copying...

How can I assign a separate grid to two separate Y-axis? I have a chart that has a custom Y-axis from 80-100% and the default Y-Axis from 0-80%. The first Y-Axis also has a custom X-Axis. But the grid of both chart areas reach over the whole chart. How can I change this to have one grid in the lower...

Thank you very much! But how do I get the XPosValue from a DateTime Value?

I have a chart with an upper and a lower part, each having its own y and x-axis. Now I want to draw a ban vertically on the lower part. I can assign the band to my custom x-axis, but it will draw over the whole chart area (lower and upper part). Can I also asign a y-axis to the color band so it will...

Well, I wish it was that easy! :) My X-axes is say 400 units. My first line adds points at 201.22, 210.55, 250.37 My next line adds points at 201.99, 211.13, 250.22....and so on. Since the Add Position don´t align it will take quite a bit of calculation to get the High and Low Values e.g. at 201.00....

Hello,
can I use a chart containing many FastLine series as a datasource for a high-low graph to get an resulting envelop (enclosing alle values of all FastLine series)?

How can I add a null value in FastLine.Add(double[], double[])? I have lots of points and cannot add them one by one because of performance.
