Use ASP. NET to draw line charts and use asp.net to draw line charts.
Use the. Net drawing class to draw a line chart, generate an image, and display it on the page. The Code is as follows:

For (int I = 0; I {
StrDataName + = month [I]. ToString () + "\ t ";
StrData + = count [I]. ToString () + "\ t ";

After a long selection, I finally found the simplest solution of the Code: the chart that comes with Ms. MS charts have existed for a long time, but in previous usage, IMG needs to be saved, which will lead to MVC access conflicts (which had plagued one of our projects), roughly:
The following available:. net3.5 + MVC + MS chart
The following are unavailable:. Net4.0+ MVC + MS chart (MAGIC is that the MS chart comes from. net4.0, it seems that I forg
