CPaintDC obj(this);
x=(point.x)-50;
y=(point.y)-50;
obj.Ellipse(x,y,x+100,y+100);
it didn't work.And i also tried this by defining CPaintDC obj in OnPaint fucntion
x=(point.x)-50;
y=(point.y)-50;
CDC *ptr=CDialog::GetDC();
ptr->Ellipse(x,y,x+100,y+100);
these both are not working.

What do you mean with: "doesn't work"? Please detail.
BTW you have to use CPaintDC dc(this); inside the OnPaint handler.

Do you properly invalidate the painting area?

I made a test, and, of course , it works well.

Where you are calling Invalidate, is it after painting in the OnPaint Handler?
And are you still drawing in the move handler?
In the Move Handler just update the position to member variable and invalidate the client region, invalidate will cause the paint to happen, And in your OnPaint Handler draw the ellipse, don't call invalidate in OnPaint Handler.
If you are not painting the background by overriding the OnEraseBkgnd method, then also previous ellipse remains on the DC.

i invalidate in OnmouseMove handler not in onPaint function

Hi,
I want to zoom in the selected area on MSCHART. The area can be selected through rectangle which will be shown when the mouse moves over MSCHART.
Please help me if anyone know how to zoom this area on MSCHART.
One method i can think is shifting the selected rect origin to plot origin.
For doing this, i will require Plot area in pixels.
Thanks.

I don't know how you would do that with MSCHART but you can take a look at the link in my sig. I developped a charting control and it has support for manual zoom (with the mouse).

Thanks for reply cedric.
I checked your charting tool.
But i want to plot the XY scatter graphs. Does you tool provide that.
I also want to set all the properties og graph like
Axes properities:- color, width ,scale( min, max, major division and minor division), auto scale function, marking data points
Graph properties:- plotting points with/ without line connecting them, grid display function, labeling points, toggle title ON/OFF.
Please let me know if your chart provide this.

What do you mean exactly by scatter graphs ? Points with an X and Y value ?
sharda.bhagwatkar wrote: Axes properities:- color, width ,scale( min, max, major division and minor division), auto scale function, marking data points
Color: yes. Width: no (you mean the width of the axis line ?). Scale: partially (min&max and major division yes, but there's no minor division). Auto scale: yes. What do you mean by "marking data points" ?
sharda.bhagwatkar wrote: plotting points with/ without line connecting them
If you use two separate series with the same data then yes (one series for the points, one for the line).
sharda.bhagwatkar wrote: grid display function
You can enable or disable the grid for a specific axis.
sharda.bhagwatkar wrote: labeling points
No, there's currently no such feature.
sharda.bhagwatkar wrote: toggle title ON/OFF
Yes.
BTW, does MsChart control provide with all those functionalities ? Even for labels on points ? I thought it was not that advanced

-> Yes, with values X and Y.
Color: yes. Width: no (you mean the width of the axis line ?). Scale: partially (min&max and major division yes, but there's no minor division). Auto scale: yes. What do you mean by "marking data points" ?
-> Yes, width of axis line.
->axis scale should support -ve values also.
-> Marking data points means each point on graph should be highlighte with some symbol like cross, square etc.
If you use two separate series with the same data then yes (one series for the points, one for the line).
No, i want the functionality in which we can set the property for one series with either lines connecting between points or without line connecting between points.
MSCHART control provide all this functionalities. But just Zooming MSCHART i am not able to do it.

You can define your own message and like WM_SYNC_MYTEXT and send it to the specified control window. that message has to be handled at the tree control side (i.e derive your own tree control from CTreeCtrl) and handle message inside ON_MESSAGE macro inside the message map)
Please check MSDN
Message Handling and mapping[^]
User defined handlers[^]
There may be a better solution for your problem. What I've said is a quick solution.

Ok, so what's the problem? If you have obtained the string from the list control (into a variable of some sort), the list control is no longer part of the problem.
