Access specific points in a series


Recommended Posts

Hi,

I am converting a colleague's code (C#) which was written for the previous

ChartFX release.

In his code the X & Y values for a specific point in a series could be

accessed as in the following:

MyObject.MySeries.Element.YValue =

MyObject.SubObject.MySeries.Elements[I].YValue

I can't figure out an easy way to do this with the current release. That is

if your graph has 2 series, the first has 10 points and the second only 5

points. How would you access the first, non-null point in the second series

if you have no idea where it starts?

Secondly, on a more architectural note, I don't quite see where SoftwareFX

is going with the current release. Visually it is great, but it lacks some

of the flexibility of the previous release. We use an array list of objects

to contain graphs (series) that a user can add/remove from a simple graph.

Previously we could create an object, containing a definition for a moving

average curve, for example. This object would contain a series object which

would appear on the graph when the user selected to add a moving average and

when the user removed the MA, the object, along with the series, could be

destroyed.

Now we don't have a series object, we have to use the series index (a step

backwards in my opinion) and when series are added or removed the indices

within our objects all have to be incremented or decremented.

I hope SFX can shed some light on this, am I just missing something?

All series have the SAME amount of points. This is true for all versions of

Chart FX (as of today).

You can pad "shorter" series by setting Chart>hidden to the values at the

end of it.

To access the data you do:

chart.Values[<series index>,<point index>]

and

chart.XValues[<series index>,<point index>]

I don't understand what you mean by this, there is a Series object, maybe

you can post some code of how you did this is previous versions.

Sorry about this, I had a bit of 'version confusion'.  The previous software 

was not ChartFX.
