I have problem regarding setting the uilabel in the middle edge in pie chart circle.
In my Pie chart there are 2 portion.
Both portion change dynamically.
How can i get center position in both portion so i can set my label in the center edge of the particular section.
Thank You

use carteasian equation.
(x,y) = (rcos#,rsin#).
R is the radius of the piechart. # is the angle at which you need to find a point. In your case middle of your pie slices.

Now vaadin set X axis on min vertical value(bottom) and Y axis on min horizontal value (left), but i will like set axes on middle
I'm afraid that axis are always in left and bottom of the plot area.
One thing you can do is set the min at negative, or leave it automatic, and add a plotline with value 0 for both axes. That way you can visualize the chart's quadrants.
If you're using java API you can use addPlotLine method in xAxis or yAxis classes. You can check the java tab in the boxplot demo
Problem Statement:
A bar plot in created with CorePlot has a Y-axis that features a dynamic range. The minimum value of this range is presumed to be <= 0. The maximum value of the range is presumed to be > 0.
The bar plot features custom X-axis labels which have an offset to distance themselves from the 0 line of the Y-axis. (label.offset)
However, because the exact location of the 0 line may change during runtime, a static value to offset the X-axis labels is not sufficient.
Question:
What is the appropriate way to accurately set the offset of Axis labels, when axis parameters change at runtime?
Screenshot attached to show problem. Labels should be below the ($200,000) line, but because the top end value is dynamic, they move up and down.

From the linked picture, it doesn't look like you're drawing the axis line. Use axis constraints to hold the x-axis at the bottom of the plot area. If you do want to draw an axis line, e.g., at y = 0, add a second x-axis. Use one to draw the axis line and the other to position the labels. Set all of the line style properties of the second axis to nil so it doesn't draw any lines and use constraints to hold it at the bottom of the plot area.
I would like to ask if there is a way to achieve the layout and arrangement of the circles on the image.
I would like create a chart of series of circles that are link together and all aligned in the bottom.
The distance between two circles with radii r1 and r2 is:
You can use this to position your circles on the x-axis. For an example see: http://bl.ocks.org/7a9d6c4725367aaed5db .
Is it possible to set some padding between the first bar and the Y axis?
The last bar is always a few pixels away from the right margin of the plot but the first column always appears cut by the Y axis
Adjust the xRange of your plot space. Decrease the starting location and increase the length.

How to remove empty spaces between two consicutive Axis Labels?
ie on x-Axis Label1.........Label2........
on Y Axis
Label1

Label2
Please Help and Suggest.
The labels are centered on the corresponding major tick marks. You'll have to adjust the distance between the tick marks. How you do that depends on which labeling policy you're using.
