ASP. NET provides the ability to use the datavisualization. dll dynamic class library to create charts of various styles. First, we will introduce the data tables and project structures used in this example.

You can see the <asp: Chart> </ASP: Chart> label, which is the root label (Chart label ).

Including <legends>, <borderskin>, <Series>, and <chartareas>.

<Legends> defines the description of a chart,

<Borderskin> defines the chart skin, which is an enumeration value. Control by skinstyle = "emboss.

<Series> used to bind data. The attribute charttype = "column" indicates that the chart is a column chart, which is also an enumeration type. Attribute chartarea = "chartarea1" indicates the chart display area

You can bind data in the background as follows: chart1.series ["Series1"]. points. addxy (row ["X"], row ["Y"]. tostring (); determines the point by horizontal and vertical coordinates.

<Chartareas> defines the chart display area. You can add multiple <asp: chartarea> </ASP: chartarea> On the tag side.

You can define horizontal and vertical coordinates in the <asp: chartarea> label. For example, add the vertical coordinates <axisy> </axisy> and horizontal coordinates <axisx> </axisx>.

Linecolor indicates the color of the horizontal and vertical coordinates, arrowstyle indicates the arrow style, title indicates the title of the horizontal and vertical coordinates, and interval indicates the interval. The default value is 0.

All the preceding labels and attributes can be found in the system. Web. datavisualization. xml file.
