Hi

Is it possible to draw a number of equally spaced circles (say 5) around a
point in a chart??

I mean that my chart will look like this when I run the VBA procedure.

Hi,

2 ways depending on how much control over the size and spacing you need.
First way is to plot a series of points at the same xy location use the
circle marker with no backcolor. Alter the size of each marker to get a
set of concentric rings.

For move control you will need to plot each ring as a series of xy lines
where the points are derived from simple trig formula.
Have a look at how the outer ring of the gauge chart is plotted.

If you have problems post back.

Cheers
Andy

Ali Baba:
This may qualify as a 'kludge' but, you could create your chart as a Bubble
chart.
Set your bubble series 'Options' to:
'Size represents: Width of bubbles' and
'Scale bubble size to: 220% of default'
Then, select each 'Line' series and:  'Chart | Add trendline' (format your
trendlines as you would like)

X      Y     BUBBLE1   BUBBLE2   BUBBLE3   BUBBLE4  ‘LINE1’  ‘LINE2’
2.0    1.5   4.0
2.0    1.5                   3.0
2.0    1.5                                  2.0
2.0    1.5                                                  1.0

0.0   -1.0                                                                 0.0
1.7    4.0                                                                 0.0
1.2    2.5                                                                  
        0.0
2.0    1.5                                                                  
        0.0

If you'd like I'd be happy to e-mail an example of this method.  
Unfortunately, I don't have a website I can post it to.

Sorry, my spacing did not work properly:

FOR the following series (plotted by colums):
X  Y  BUBBLE1  BUBBLE2  BUBBLE3  BUBBLE4  ‘LINE1’  ‘LINE2’

X: 2.0  Y: 1.5  BUBBLE1: 4.0
X: 2.0  Y: 1.5  BUBBLE2: 3.0
X: 2.0  Y: 1.5  BUBBLE3: 2.0
X: 2.0  Y: 1.5  BUBBLE4: 1.0

X: 0.0  Y: -1.0  'LINE1': 0.0
X: 1.7  Y:  4.0  'LINE1': 0.0
X: 1.2  Y:  2.5  'LINE2': 0.0
X: 2.0  Y:  1.5  'LINE2': 0.0

I have to apologize to anyone reading this (attempted) post:
There is one more thing I need to add to get this method to work:
Create your first Bubble series.  Once the chart is created, select your
chart, and go to 'Chart | Source data | Series' and add your successive
bubble series through this form.  Then, add the trendlines to the 'fake' line
series.

I prefer something like when you click on a point this will show the circles

Or you click on a command button and specify the coordinates
