Pie Chart in QlikView - Controlling Colors - qlikview

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.

Tableau (Highlighted Tabs) - Create color range

I started working with Tableau and want to create a crosstab that displays a measure per customer over the months.
The goal is to Display every value >95 as green, the values from 85-95 as yellow and everything below as red. Is this possible?
Thanks a lot in advance.
So I start with a view of this
Then I create a dummy calculated field which will represent my color scheme
I drag the Value Color Sum to the color, then the numbers will be colored.
To change the color, click on the color button.
To create the "background", I take the "Number of Records" and drag it to Size.
Then I take the measure and change the marks from "Automatic" -> "Bar". I also click on the small white triangle and choose: "Measure" -> "Minimum" to make the bars in the background to fill up the whole cell.
Then I left-click on the size button and drag the slider to the right to make the bar fill the height.
Video of above steps can be found here: How to Conditionally Format Cell Background Color in Tableau
Depending on your data you might need to adjust your measure to make it aggregate, it depends on your data.
For example, my data looks like this:
If I don't aggregate the data the result will be as picture below, since the color will not be applied to the sum of customer A, rather it will be applied to each "row" and therefore the cell will be RED instead of GREEN (See value 110 for January, Customer A).
By aggregating the value I can direct my color scheme to this variable which make the result as I desire.
In this case I used a LOD on customer and Month to create my Sum Value:
{Fixed [Customer], [Month]: SUM([Value])}

Can you force a label on top of a bar chart in SQL Server Reporting Services?

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:

JFreeChart Ring Chart : Only Legends section is displaying but Ring Chart is not displaying

Can anyone help me out Why Only Legends section is displaying but Ring Chart is not displaying IF the data set has more data records say > 50. I have stuck with it.
Depending on the data, that may be too many values to display usefully. You can try the static method DatasetUtilities.createConsolidatedPieDataset() to derive a dataset that is "modified by aggregating all the low value items (those whose value is lower than the percentThreshold) into a single item with the key "Other".
Is there any other way to increase entire chart size?
I'd override getPreferredSize() in ChartPanel like they show here.

rdlc: Display percentage on pie chart

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...

Reporting Services 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")
