Access Pie Chart driving me crazy

kuznickic · January 11th, 2009, 10:51 AM

Hi all,

I am trying what I would think is pretty basic but I can't figure it out. I have one yes/no in a table that I want to display in a pie chart. I want to show all the yes and all the no's. I have created a query that counts the yesses and nos so that should populate the pie chart. I just can't figure out how to display this and like the title says it is driving me crazy. Any help would be greatly appreciated.

Thanks,
Chris

Okay can somebody anybody please please help. I am getting desperate and have spent about a whole day researching and can't figure this out. I am begging anyone to help me.

Here is what I did.

I created a table with a Yes/No field, and populated it with sample data.

I then created a query that looks like this:

Query1:
SELECT Count(Table1.SampleID) AS CountOfSampleID, Table1.YesOrNo
FROM Table1
GROUP BY Table1.YesOrNo;

This grouped the Yes and No responses and gave me the following output in the query:

CountOfSampleID YesOrNo
5 Yes (checkbox)
3 No (checkbox)

I then created a report in Design View, and inserted a chart in the Detail Section:

Insert > Chart > Queries > Query1 > both fields > Pie Chart > Next > Name: Chart1

Then I open the report and the chart shows up as it should, with the legend -1, 0. This is because I didn't change the actual field to a Yes / No selection but kept the default -1/0.

What are you doing that is causing problems?

Thanks mmc,

I'll give that a go. I think the problem rests more with my understanding of how pie charts work than Access. I know VBA but never really had to create any kind of charting capability before. Charts for whatever reason confuse me. I can create a query and view the chart in PivotChart view in the query but I just can't seem to make it work when I go to the report and try to create a chart in design view. The query I am using is this

Code:

SELECT Sum(Abs([Complete])) AS Completed, Sum(IIf([Complete],0,1)) AS NotComplete, Count("*") AS Total
FROM tblDiscrepancies;

. I think too that the chart designer in Access is not that intuitive.

Thanks,
Chris

Works like a charm. I knew it couldn't be hard but for whatever reason that problem was kicking my okole.

Again many thanks.

Okay just one quick question. How do I change the labels to say Complete and Not Complete.

Thanks
Chris

What do the labels say now???

I would *HOPE* that the chart is smart enough to pick up the names from your SQL query. Which means you SHOULD be able do do

Code:

SELECT Sum(Abs([Complete])) AS [Complete ], 
       Count(*) - Sum(Abs([Complete])) AS [Not Complete], 
       Count(*) AS [Total]
FROM tblDiscrepancies;

(Hope you didn't mind my simplifying your query slighly.) I put a space into [Complete ] so that the name would be the same as the name of a field. Sometimes the query engine chokes if you use a field name for an alias. It shouldn't, but it does.
