Where is the Graph Control in VB.NET?

Am I going mad, or is there no control in .NET that will allow me to display
a simple graph of a series of points held in an array?

Please tell me I'm wrong.

Hi Ken

I have had a look at this, but no graph/chart controls leap out at me. Do
you happen to know what they are called? I see Infragistics there, and I
have the full set installed, but this provides a charting control - bar
charts and stuff - but as far as I can tell it does not offer the simple
facility of displaying a graph.

Charles
 
Thanks Ken

It is on the right lines, and I can certainly think of some uses for it, but
it would need modification to make it into a graph control. I'm really
trying to save myself some work, and I thought it would be an obvious
control to include in .NET, just like classic VB.

I'm still surprised that there doesn't appear to be a standard control for
producing a simple graph.

What Dundas isn't going to do it for you??? =)

Ah, I see, it's all in the punctuation.

I'm probably missing something here, but I already have Infragistics
WinChart stuff, and judging by the name I suspect it is much the same as the
Dundas control.

The emphasis appears to be on 'chart'-ing, as distinct from 'graph'-ing. I
spent some time with WinChart and found no reference to drawing a graph. The
way in which data is supplied to a chart is different from how it is
supplied to a graph. For example, WinChart allows a chart to be bound to a
DataTable. Each row corresponds to a group, and each column to a point in
that group. If I wanted to plot a graph with, say, 1000 points on it, I
would need to create a DataTable with one row and 1000 columns. This doesn't
seem to be the right way to go about it. I had hoped that I could pass an
array of points and the control would join the dots.

Hi C J

I have being trying the Dundas evaluation this afternoon, and have
discovered how to produce a graph.

Thanks

Charles,
For Infragistics you could try making a LineChart and set the
SwapRowsAndColumns flag to true thereby allowing 1 value with n rows of
data. I haven't tried this but that is how the V3 documentation says to do
it. I'm not sure this is what you want though as it doesn't allow spacing
the datapoints other than linearly.

Hi,

There are some chart controls there that come with visual
basic
resource kit. Hope that helps.

Hi Ron

I think that will be the problem. Both the x and y co-ordinates may have
irregular spacing, but I will take a look at it.

Thanks.

Hi Herfried,

Hi Welcome back,

I was expecting you friday, so was afraid something had happened.
u have changed your name to a realname?
Click to expand...

My name is always been a real name as I always have said.

You see with more Dutch speakers we only use our firstname.

And I think that I have collected all Ligtherts in the world, so not using
my lastname makes no sense anymore.

I was /very/ tired after my ~30 hours trip from Seattle to Austria.

We use our firstname too when talking to each other, but there are many
"Michael" or "Peter" in Germany, so it will be very hard to make a
distinction between them. I assume, that there are many people with the
name "Cor" in The Netherlands.

Not so in the Netherlands, but very common in Holland and Zeeland.

I did once to a search for Herfried in Google, and yes you where in front,
that is an almost non used name I saw.

ACK. There is only one other popular Herfried who is stealing me the
1st place in Google's Web Search. But that's very OT...
