I have created a simple bar chart... which is bound to an array... size of array is unknown... is it possible for me to make a chart which have same bar widths even there are 2 record or more... current bars become thicker when there are less records....
second thing is when I have lets' say 1000 bars in chart the PlotArea is too small for these number of bars... it creates a mess with scale and bars... i need a chart that have same same bar width for any number of charts and dynamic PlotArea...
please help

Hello Abdul,
Even though you don't know the count of the bars you can use the maximal value of the chart Bars and set it as MaxValue of the XAxis. To be able to do this you should turn off the XAxis.AutoScale proeprty and provide your own values for MinValue, MaxValue and Step. This way, you will always have the same number of items along the X axis, so the bar will always be with the same width.
Setting custom scale with appropriate Step will help you resolving your second issue too.

I have plotted my x-axis accordingly... and currently using zoom property to view my all millions of bars (plots) in reasonable size. I'am more concerned with my second question i.e. to draw a custom sized PlotArea. So the chart size become as much larger as the axis is..
However i have received this reply on dynamically growing chart size question... some what related to this question

"RadChart creates an image on the server and sends it to the client so there is no way on the client side to change that size. The solution is to use JavaScript and send requests to the server."

Hi Abdul,
RadChart renders a normal image on the page, which does not have any dynamic values to resize itself. This how ever can be achieved with the help of some javascript for manually altering the image width/height. Take a look at the following Code Library - http://www.telerik.com/community/code-library/aspnet-ajax/chart/resize-chart-image-in-radsplitter.aspx and more specifically the ClientSide resizing.
