I don’t have this in ready-made form, though I know how I would do it. It would take a couple hours to hack it together, though, and I’ve been rather busy. Well, maybe less than two hours, since the dartboard chart itself is already built.

If any of my readers happen to have built something like this, let Hans and me know. Otherwise, maybe I could do it as a demo sometime soon.

At the moment we have a dart program that uses buttons to enter the score
i’m looking for a way to make a Dartboard and enter the score by clicking on the image.

Would it be possible to receive to code for this dart board

Yeah, that one’s pretty bad. Maybe I’ll post about it.

I just found a good use for the exploding pie slices: one of the things that the pie-donut combo is not so good at is labeling the sectors. You can choose to put the data labels for the pie in the center of each sector, or the “inside end” or “outside end” (bar chart terminology)

But donuts don’t have this option for label position, which means I have to resort to e.g. dummy series. However, a pie-pie combo with the top pie exploded and shrunk enables me to have center labels in the top, inner pie and outer labels on the bottom, outer “donut”.

I meant to say that you don’t owe Microsoft an apology for any behavior, intentional or otherwise, which they have neglected to document anywhere. The weakness with these undocumented behaviors is that they have a greater chance of being left out of future versions when substantial changes are made. I need to check out how Excel 2007 handles this unorthodox mixture of chart types.

In the last beta, I commented on a number of behaviors which had changed or disappeared. The question invariably was, “Why would anyone want to do that?” When I described a scenario for exploiting the behavior, the response invariably was “Oh.” The point is, once you have a behavior in place, people are going to find it and use it. You should have a very good reason to change (and especially to remove) this behavior. And “I didn’t know” is a poor excuse.

Clever detective work. I had tried making a pie chart with two series, and while the source data range included both ranges, and the Source Data dialog showed two series, there was only one apparent series in the chart. So I just assumed it didn’t work that way. However, now I can think of easier ways to get what you want.

Make a line or column chart with two series, A and B. Move series B to the secondary axis. Change series A to a pie chart. It appears in front of the line chart, but it remains on the primary axis. Change series B to a donut chart. The series B donut will appear in front of thee series A pie.

Say you have n series, where n is two or more. Start by using the Chart Wizard to make a donut, on the worksheet, out of *two* of the series. Only two, the rest come later. Now convert one series to a pie; this is the series you want to eventually be the pie in the middle underneath the donut. This will jump to the top, obscuring the other series. Now select the other, hidden, series (I prefer to use the keyboard to step through, but if you really prefer the mouse, you can use explosion to expose the hidden donut)

Convert that series to a pie also. It will now jump to the top in its turn, obscuring the first pie. Convert it immediately back into a donut: the point of making it a pie was only to get it to the top. Finally, you can use the range handle to drag the chart range to include the other series, which will then be added as extra, outer donut rings. If you prefer your charts in chart sheets, now is the time to use Location.. to move it. If you do make your combo graph in its own sheet at first, you’ll have to use Copy.. Paste Special to add the other ranges at the end.

You can move the donut hole in and out to your taste, with no danger of exposed midriff, since the pie now covers the entire field, underneath the donut.
