When creating bar chart using our ASP.NET AJAX controls, we can not only change its appearance and attributes using property panel directly but also modify its data series using C# code. And this article will guide you to build a simple bar chart using C# sample code.
Before doing the modification using C# code, you need to drag an AjaxPanel item to aspx page and put a chart control from toolbox to that AjaxPanel. Basic Settings

And sometimes, you may want to view 100 stacked bar chart in the html page, each bar will separate to multiple parts, and each group data will take over some area in each bar chart according to the data content.
C# Code for Customizing Chart Skin

And this performance can be done with the help of following sample C# code.
Define Chart Axis Using C# Code
The axis has two dimensions, which are xaxis and yaxis. To better present the values of each data series, we need to customize the scaling and spacing values of the axis based on our own data source. If the scaling is too large, the bar chart will be too small to be read. Here we offer sample C# code for defining and customizing both xaxis and yaxis settings. If needed, you can view more settings for chart axis at set chart axis element with c#.
