I've been using Infragistics UltraWebChart v. 5.2. If the number of records is larger in the DataSource and the size of the image generated is small (dimensions are 350px width and 183px height) then the column graph generated doesn't show any bars for the graph.

Please suggest the solution to this problem
it sounds like you have < 2 pixels of horizontal space available per column. i think the best solution is to enable scrollbars on the x-axis.
try setting EnableScrollbar = true. this will zoom out 50%.
alternatively, try setting the chart's width to something large like 1000px and put it in a scrolling DIV.
