C # 's Chart article

叕 叕 叕 to Friday, time always go so fast, unavoidably sad (-) ... (Sad a wool, again sad 16 is gone) December will be over, hurriedly to a full life. Recently in the project, made a chart program, using the chart, today to do a collation summary. 1. The first chart control 1 First to familiarize yourself with the chart, in front of a chart may be used to chart.js, in C # can be used with the control of the chart, feel very convenient. 2 Create a project, Windows Forms application. Locate the "Chart" control in the Toolbox's data and drag it to the form

3 Right Key Chart "Properties", in vs Right Property "layout" to find the "Dock" property set to fill, adjust the size yourself

4 The operation here is to display chart when the form is loaded, so there is a form load event.

5 Double-click directly into the code, when written in the code Series will appear red wavy lines, prompted the lack of related namespaces and so on, click "Series" can see the need, add on the OK

            Series.clear ();  
            New a series called "strength" Series strength = new Series ("Power");
            Sets the type of the chart, here for the columnar graph strength.charttype = seriescharttype.column;
            Assign values to the points on the series, respectively corresponding to the horizontal and ordinate values Strength.Points.AddXY ("A", "90");
            Strength.Points.AddXY ("B", "88");
            Strength.Points.AddXY ("C", "60");

            Strength.Points.AddXY ("E", "79"); Strength.Points.AddXY ("F", "85")); Add the series to the chart Chart1.       

        Series.add (strength); }

} 3) Effect

4 familiar with common properties and Methods (1) Series Objects

Series strength = new Series ("Power");
Series speed= New Series ("Speed"); Set Series Type

Strength.charttype = Seriescharttype.column;
Speed.charttype = Seriescharttype.spline; whether to display the value as a label (default false)

Speed.isvalueshownaslabel = true; Set Series color

Strength.color = System.Drawing.Color.Cyan; assign a value to a point on a series

            Strength.Points.AddXY ("A", "the");
            Strength.Points.AddXY ("B", "the");
            Strength.Points.AddXY ("C", "60");

(2) ChartArea (which is the area we see) Show in the form of a

Chart1. Chartareas[0]. Area3dstyle.enable3d = true; Set axis Title

   Chart1. Chartareas[0]. Axisy.title = "attribute";
            Chart1. Chartareas[0]. Axisy.titleforecolor = System.Drawing.Color.Crimson;
            Chart1. Chartareas[0]. Axisy.textorientation = Textorientation.horizontal;

Set the grid interval (set to 0.5 here to see a little more intuitive)

Chart1. Chartareas[0]. AxisX.MajorGrid.Interval = 0.5;

The report's devices include devices that have records of the underlying data being maintained, and devices that have records that do not maintain the underlying data ( 1) Functional Code structure
