Draw graphs in VB6

[raghunadhs]

Hi All,

I have few pairs of float vlues, like (1.5,4.5),(4.67 ,8.90)..etc.
Now i want to draw a graph among the points. is there any "Graph" control? is it possible to draw graphs in V.B 6.0? if it is possible,kindly let me know it.

Thanks in advance:

Hi,

Use this Line Function :

[code=vb]
Me.Line (X1, Y1) - (X2, Y2)
[/code]

As QVeen72 points out, you could draw it all yourself, using the graphics methods such as Pset and Line. However, probably your simplest approach would be to use the MS Chart control.

Thanks QVeen72, and Killer
could you give me syntax, how to use chart control? i have found that control in components, and dragged and drooped on the form. but i don't know how to use it. if possible kindly give me a sample code also..
Thanks in advance:

Hi,

What I feel is, MSChart Control and most of such controls rely on the Data and Draw a graph, Say Compare Customer wise Sales for Previous Year and Present Year, U need to give the Amount of Data and the Graph Lines, Re-Adjust itself... Since have the CoOrdinates of Points already, U better use "Line" function.

Sorry, I don't have any experience with the MSChart control. If you try the search box, you'll probably find other discussions about it here though.

[raghunadhs]

Ok, Killer,no problem i will search...

and Qveen, i tried that line method.

instead of x1,y1,x2,y2 i substituted my own values.. is it right? or any thing else. if it is correct, how can i draw lines for small readings like (5,6),(8,9) like that?
if what i am thinking is wrong, please provide me a sample code...

If you use MS Chart control, it can be connected to database easily.

Hi, debasisdas,
I don't want to connect with database. I just want to plot a graph, with set of (x1,y1),(x2,y2) pairs. And those readings may be floating point. I want a way to do this. It may be either regarding to MS Chart or Line method of graphics.

If you know how to do it in MS Chart, kindly let me know the syntax.

please try this sample code
[CODE=vb]Dim X(1 To 7, 1 To 6) As Variant

X(1, 2) = "Rice"
X(1, 3) = "Corn"
X(1, 4) = "Lentilis"
X(1, 5) = "Wheat"
X(1, 6) = "Rye"

X(2, 1) = "JANUARY"
X(2, 2) = 2
X(2, 3) = 3
X(2, 4) = 4
X(2, 5) = 5
X(2, 6) = 6

X(3, 1) = "FEBRUARY"
X(3, 2) = 4
X(3, 3) = 6
X(3, 4) = 3
X(3, 5) = 10
X(3, 6) = 18

X(4, 1) = "MARCH"
X(4, 2) = 1
X(4, 3) = 3
X(4, 4) = 8
X(4, 5) = 7
X(4, 6) = 9

X(5, 1) = "APRIL"
X(5, 2) = 4
X(5, 3) = 6
X(5, 4) = 13
X(5, 5) = 10
X(5, 6) = 12

X(6, 1) = "MAY"
X(6, 2) = 2
X(6, 3) = 9
X(6, 4) = 9
X(6, 5) = 12
X(6, 6) = 7

X(7, 1) = "JUNE"
X(7, 2) = 13
X(7, 3) = 20
X(7, 4) = 5
X(7, 5) = 18
X(7, 6) = 11

MSChart1.ChartD ata = X[/CODE]

please try this sample code ...

Very nice! :)

Thanks for that, debasisdas. I think we should write this up for the Articles area.

ok i will post that as an article with some explanations.

Hi debasisdas,
This was very nice. there is no doubt. i think it is a bar chart. but i need a graph.Means user should be able to draw lines between (x1,y1),(x2,y2) points.and these number of points are depending upon the user's choice(it may be 10 or 15)
egg:
( X1 , Y1) (X2 , Y2)
(2.34 , 3.12), (5.45 , 8.78)
(6.98 ,10.23) (3.67,13.56)


if i could not explain this question much better, please let me know it.so that i will try to post this thread with more clarity.

if u want lines, not chart then use

[CODE=vb]Me.Line (X1, Y1) - (X2, Y2)[/CODE]
as already suggested by Qveen

[QVeen72]

Hi Raghu,

If u have Small Readings and want a Clear Picture, u can Multiply By Some Common Factor say 10,
So if ur Line is (4,6) to (8,7)

U can Draw, (40,60) to (80,70)
