I'm using Visual Studio 2010 reporting to generate a report which has a table and a pie chart. Both work just fine except that for the pie chart, I'm to put the % value on each pie chart slice.
1. Is this even possible?
2. If it is, how do I do it?
Thanks
To put the % value on each pie chart slice do this (as shown here):
On the design surface, right-click on the pie and select Show Data Labels. The data labels should appear within each slice on the pie chart.
On the design surface, right-click on the labels and select Series Label Properties. The Series Label Properties dialog box appears.
Type #PERCENT for the Label data option.
Beware: If you use multiple data fields like this:
you need to move every field to first position and perform above steps as shown here otherwise you end up with only one pie chart slice showing the percentage and the others are blank...

I want to have on the same page a pie chart and a bar chart, with trellis pages.
They both have 5 columns as trellis, so 5 different pages that you can visualize by scrolling down.
However, I would like to display the same pages at the same time for both graphs. For instance, let's imagine I'm on the pie chart, I scroll down one page - and so my pie chart is on page2 - I want my bar chart to automatically go to page 2 as well
I tried to use markings but although it links a bit the two graphs, it doesn't change the trellis pages automatically
Does anyone know how to do this ?
as #scsimon mentions, there's no native feature (nor API method, AFAIK) for this using a trellis. however, you can create a Property Control (I'd use a dropdown) in a Text Area, then use the same Document Property to your chart in a Limit By expression.
little more detail, assuming a data table like this:
A B CATEGORY
1 2 red
3 4 red
5 6 green
7 8 green
9 10 blue
11 12 blue
add a Text Area to the page and edit its contents
add a Property Control
click New to create a Document Property, give it a type String and a name category
change Set property value through to Unique values in column and choose the "category" column and click OK
save the Text Area contents
in your Pie Chart's Properties dialog, go to the Data page and look for Limit data using expression. click Edit
set the expression to: [CATEGORY] = "${category}" (don't forget the quotes or the Document Property won't be treated as a string and you'll get an error)
repeat steps 6 & 7 for your other chart
As #scsimon mentioned in the comments, it seems to be impossible. I found a way to have a similar representation though without using trellis visualization, by using text arena
I created a list box that contains the 5 columns I want to visualize, and then I select this list box as the vertical axis variable of the bar chart and the sector size of the pie chart
Then, by clicking on my list box, I can have a synchronized Pie chart and Bar chart (a bit different from what I expected but it also has some advantages like a multiple scale since a new graph is generated independently of the other variables)
I would like to ensure the labels of my bar chart are above the bars. Can you force a label on top of a bar chart in SQL Server Reporting Services? If so, how?
The issues are the colors are so dark, it's hard to read them if they are not above the bar in the chart. I could just change the colors, but I'd rather learn how to force the label location if possible.
I'd like all numbers to be above the bar, like over the blue bar below. I have over 100 different charts in my report, so the scale will vary greatly depending on the particular report.
Thank you!
In Visual Studio, design mode, ensure that the properties window is visible, then click on any of the labels on the chart.
At this point, the properties window should show the properties for Chart Series Label.
Find the 'Position' property, which probably is showing the value 'Auto', change this value to 'Top' and this should do the trick.
You have to first make sure the chart type is not stacked.
In my experience the "Position" property doesn't always work.
Sometimes you have to go to the properties of the series, then "Custom Attributes", then "Label Style" then select "Top".
What #niktrs said in the comments of the other answer about setting the AllowOutsidePlotArea property is also true.
Microsoft do not use the label Position property for some of the chart types.
They tell us what they use by default here - in your case "on bar charts labels are placed outside of the bars that represent data points" (they appear to mean "column charts")...but sometimes with a large value it's placed just inside, sometimes partially in-out (and if you try the "Outside" position it just fails to render!).
As #jayvee has mentioned the trick with Column charts is to select the value and change the SmartLabels AllowOutSidePlotArea to True (from Partial).
However if you have a Stacked Bar chart then labels are always in the centre of the particular value.
The hack to get labels on top is to add an extra Stacked Bar value with the Color set to "No Color" and move it to the top of the values (using the Chart Data designer arrows).
The trick is getting a good expression value to use - a constant ends up too big or too small at some point, so I found a percentage of the stacked values works best (remembering to change Nulls to Zeros)...25% to 30% usually works.
Then set the value Label to the value you want to display in the data label.
I just had this issue, I was able to fix it by making sure the chart series "Smart Labels" - "Disabled" property was set to "True"
This is what my properties pane looks like:
I have a calculated dimension that yields following values: 'N', 'P', 'K'.
On top of that is an expresion. Also I am using PIE CHART to represent the data.
The numbers are calculated ok. I need help in selecting colors for the dimension values. There are predefined colors that each dimension values needs to have. How can I imprement that? In "Expression" Tab -> "Background Color" I can't reference the dimension, since it it a calculated dimension.
I appreciate the constructive feedback.
With some chart types comes a 'Colors' tab in the chart properties window. If you go to that tab you will be presented with numerous color options for your different dimensions (calculated or not):
Change the colors to your liking and watch the Pie Chart update.
Check the 'Persistent Colors' checkbox to keep colors assigned to dimensional values.
I am maintaining a product developed on Dundas Dashboards v 2.5. In one of the dashboards they are rendering data in Pie Charts and Bar Charts. For bar charts on the y axis the values appear as Million. I mean 6M , 8M. But in pie charts the value shows up as 6000000 for 6M.
Is there any setting in Bar Charts that displays data as 6M and 8M etc. One more thing to note is that they are using the same dataset to display the data. So, I am assuming that there is some setting at the chart level.
Any ideas and suggestions are appreciated!
Select the bar chart in the dashboard designer. In the property grid, drill into the "Y Axes" property, and from there into the "Scale" property. At the bottom of the Scale properties, there is one property called "Label Format". Copy this value, and paste it into the same property for the pie chart.

The pie chart is driving me nuts...Excuse me if I sound ignorant but I have figured out the other RS charts with relative ease, and this is the first time I have had to use the Reporting Services pie chart.
I have a dataset:
Columns:
ChildId int
AssessmentType varchar
Score int
All I want is to have a pie chart that displays the percent of the whole for each assessment type. So if I had 10 records returned with the following:
2 "THIS" Assessment Types
5 "THAT" Assessment Types
3 "THEOTHER" Assessment Types
I would want the pie chart to show that the "THIS" Assessment peice of the pie is 20%, the "THAT" is 50%, "THEOTHER" as 30%, but I cannot figure out how to set it up. Can any one help me out on this, or refer me somewhere. I have been looking for some time and can't find any pages that have helped me with this control.
I figured this out...To show the percentage:
Right click on the chart and click on properties.
Go the the Data table, select your "[Value]" and click edit.
Go to the Point Labels tab and check "Show point labels".
In the format code enter P
Edit the expression and calculate your percentage. In my example I would use the code below.
=Count(Fields!ChildId.Value) / Count(Fields!Childid.Value, "MyDataset")
The problem I was having is that I was filtering the data set at the chart level with a filter expression. So when I was trying to calculate the percentage using the code below my numbers were getting thrown off. The filter is not applied the dataset count when retrieved like I was doing it.
Count(Fields!Childid.Value, "MyDataset")
