Forms :: Display Pie Chart Which Is Not Linked To Table / Query?

I have a status form which I use to show users the progress of various routines as they are performed. It's pretty basic; just a textbox and a couple of coloured labels; one for the outline ('things to be done') and one for the progress so far ('things done').

I have a function which I call periodically during the runtime of the routine which passes as arguments the text to display in the textbox (i.e. a description of which 'thing' is being worked on at that time) and two long integers representing what is 'done' and what is 'to be done' (i.e. 3 'things' done out of a total of 7)

So if I can divide a function into 7 distinguishable 'parts', I would call that function 7 times during the life of the overall process to show the updated status each time.

The function redraws the labels (i.e. sets the width of the 'done' label as a proportion of the width of the 'to be done' label, based on the ratio of the two arguments) and repaints the form. So you get a nice animated progress bar which can be easily controlled by calling the same function and just incrementing the 'done' argument each time.

Now - and admittedly this is purely aesthetic and for my own curiosity rather than anything fundamental - I was wondering if it were possible to represent this progress as a 3D pie chart rather than a horizontal bar (label)?

For no other reason than I think it would look really tidy.

I know it's possible to add a chart object to a form but the chart wizard insists I link the chart to a table or query. In this instance, I don't want to do that; I merely want to draw a very basic pie chart based on the two values passed as arguments to the status function.
