```Suppose the radius is in cell A1.

Then, in B1 enter the formula =ROW()-1.  In C1 enter =B1/180*PI(), in
D1, =\$A\$1*COS(C1), and in E1 =\$A\$1*SIN(C1).  Copy row 1 to 2:361.  Plot
D1:E361 in a XY Scatter chart.

Once done, adjust the chart so that the x and y axis have the same
min/max values.  Also, select the plot area and extend it as close to
the chart area as possible.  Finally, select any cell.  Then, hold down
SHIFT and select the chart.  Now, select Format | Object...  From the
Size tab, set the height and width to be equal.

having trouble creating chart to show monthly totals

Extra line in chart shape text in Visio 2003
When adding text to a chart shape, Visio always adds an extra line on the end. I can go back in and delete it, but it comes back when I click off the shape. I can't find any option setting that governs that action. How can I remove the extra line permanently? Can you be more specific about which shape? Some shapes are defined with the text block containing custom properties. For example, the poistion shape in the OrgChart stencil has a text block that contains two custom properties, one for name and the other for title. If you enter text into the text block, you may see an empty...

change the legend text in a surface chart
I am using a chart type of surface contour. Is there a way to change th text in the legend -- Message posted from http://www.ExcelForum.com Hi vacaut, The text in a surface chart legend is related to the Scales Maximum, Minimum and Major values.

I have Money 2002 installed on an Win XP Pro SP1 machine. Something happened and I probably did it, that causes the statement downloads not to go directly to the account. Rather they want to be saved in a file and then opened into Money. I then have to delete the download. I have tried several things in order to fix this: 1. I verified the file associations of OFC, OFX were correct. They were. 2. Lowered all my security settings in IE. Even put banks into Trusted site zone. No go. 3. Made new accounts. Didn't help. 4.

is this possible? reload a form that is based on a query with new query that is defined in the form.
I have a basic form. The form is based on a query, so when I open the form, a pop comes up where I enter in what I want to query.

I want to be able to enter in what I want to query next and afterupdate have the recordset/form reload with that query instead of my original qeury. I figure this has to be done with VB.

Can anyone help?
Take a column of data. The data in about half the cells of that column are all hyperlinks. The data in the rest of the column's cells are not hyperlinks. And needless to say, all the data (cells) are jumbled up. Is it possible to sort the data alphabetically so that all the hyperlink-containing cells are grouped together in one block, followed by another block of non-hyperlink data? Any help would be much appreciated. Gerry My first impression is to add a helper column in which there is a formula - =IF(ISNUMBER(SEARCH("WWW",A1)),0,1) This will test cell A1 for the...

2007 line chart, can't make some gridlines heavier than others
Hi, I had a nice line chart in 2003 with two lines, one for Planned and one for Actual. Across the bottom axis I had years, e.g. 2006, 2007, etc. These years were major gridlines formatted in heavy black and ran vertically. Up the left vertical axis was percent. The reports come in quarterly, therefore, between each yearly heavy gridline, there were 4 quarterly gridlines. So every 4th gridline was heavy black (representing the start of each year), and in between were 3 quarterly gridlines that were light black. The difference between the heavy annual lines with the 3 ligh...

Blocking fields to avoid use in formulas
Is there any possibility to block the particular field in order to avoid users to use invalid fields in formulas ? regards Peter You can lock and unlock cells (then protect the worksheet) so that users can't change certain cells. But if you allow them to type a formula into a cell, then I can't think of anyway of stopping them from pointing at A1 when A1 shouldn't be used. Is that what you meant? If it is, maybe someone else has a way... If it's not, maybe you should rephrase your question. Piotr wrote: > > Is there any possibility to block the particular field i...
