How to dispaly dynamically changes Y-Axis values for each request.
For exmaple data:X-axis and Y-axis data for ecach requset. but Y-axis data will change dynamically for each request.
X-Axis -- Y-axiss
------------------------

12/05/2014 2200
01/26/2015 21000
==============
11/10/2014 0.56%
12/19/2014 0.62%

Note: Y-axis value has Min and Max values. The value is less than Min value then display in Green bar and values is Grater than Max value disply in Red and in between display in Yellow Bar.
How to diplay this type of data in silverlight using xamDataChart with bargraph in diffirent colors as mentioned above.
Hi Venkateswarlu,
You can change what values are shown in the Y axis by changing the Minimum and Maximum properties. If one series requires the ability to show data points with 2000, 2100, and 21000 as the Y values then setting the Minimum and Maximum to encapsulate update the Y axis labels to show that range. The same for a different series needing to show percentages. You cannot have one Y axis showing all of these different values though. A single NumericYAxis can only show a range of values between a minimum and a maximum.
For changing the bar colors, I'm a bit confused by your requirement. If you have the Minimum and Maximum values set, and your bar value is less than the minimum, the XamDataChart is not going to show that bar so there is no point in giving it a color. However, if you need to change the color of the bars, please see the following forum thread:https://es.infragistics.com/community/forums/f/retired-products-and-controls/48210/colouring-columns-bars-in-the-chart-based-on-value/256989#256989
Hello Sir,
Y-Axis starts with Zeero as Minimum value. In my date all rows contains Minimum and Maximum Values and also contains result values with corsponding dates. I want draw bar garp with Result values(Y-axis) and Dates(X-axis). If the Result value is less than Minimum value show in green, greater than maximum value show in Red and in between show in Yellow.
Can you please send me example.
Thanks,
Sorry for the late reply. I actually reworked the sample so that instead of calculating the desired color inside a behavior, I calculate it inside each data point separately. I then just pull the color from the data point and use that to color each column. This also allows me to easily bind the tooltip template to use the color. By default the template will use the Series.ActualBrush for the color so overriding the template is a must if you want to change its color. Take a look at my attached sample.

Just realized that this is in the Silverlight forums. I updated the sample to use Silverlight rather than WPF. The approach is still the same though.
I attached a sample that changes the color of the column based on the result in relation to a min/max value. Graham's code from that previous forum post I linked doesn't appear to work anymore in newer versions of the chart so I created a Behavior<T> that will do this instead. The Behavior<T> handles the RefreshCompleted event on the chart and then grabs the Rectangle objects from the ColumnSeries canvas. It then sets the Fill property based on the Result value.
