Winform "zedgraph Bar Chart" control development of catering system based on experience sharing

This article is mainly to share with you the use of the "zedgraph Bar Chart" Control in the new module development of the catering system. Let's take a look at the effects I have applied in the project:

As shown in, this bar chart only has the Y axis, and the color of each column is different-NO x axis, but the name and score of each constitution need to be displayed, which needs to be in the regular (online example) and then make modifications.

KeyCodeAs follows:

   Void  Showbar (  Double  [] Tzzhfarr)
{
  String  [] Tztypearr  =  Comhelper. gettztypearray ();
Dictionary  < Int  ,  Double  []  >  Dict  =     New  Dictionary  <  Int  ,  Double  []  >  ();
Color [] colorarr =  {Color. Orange, color. palegreen, color. slateblue,
Color. Pink, color. Green, color. lightskyblue,
Color. Gray, color. greenyellow, color. rosybrown };

  This  . Zedgraphcontrol_res.suspendlayout ();

  This  . Zedgraphcontrol_res.controls.clear ();
Zedgraph. graphpane mypane  =     This  . Zedgraphcontrol_res.graphpane;

Mypane. Title. Text  =    "  Bar Chart of Physical Fitness Test Results  "  ;
Mypane. xaxis. Title. Text  =     ""  ;
Mypane. yaxis. Title. Text  =     ""  ;

  Int  Start_x  =    5  ;
  Double  Tzzhz  =     0  ;
  For  (  Int  I  =     0  ; I  <  Tztypearr. length; I ++  )
{
Tzzhz  =  Tzzhfarr [I]  <     0     ?     0  : Tzzhfarr [I];
Zedgraph. baritem bar  =  Mypane. addbar (  ""  , New     Double  [] {Start_x },  New     Double  [] {Tzzhz}, colorarr [I]);
Bar. Bar. Fill  =     New  Zedgraph. Fill (colorarr [I], color. White, colorarr [I]);

Zedgraph. textobj mytext  =     New Zedgraph. textobj (  String  . Format (  "  {0}, {1}  "  , Tztypearr [I], tzzhz), start_x, tzzhz  +     3  );
Mytext. Location. coordinateframe  =  Zedgraph. coordtype. axisxyscale;
Mytext. Location. alignh  = Zedgraph. alignh. Center;
Mytext. Location. alignv  =  Zedgraph. alignv. Center;
Mytext. fontspec. Family  =     "    "  ;
Mytext. fontspec. Size  =  16f;
Mytext. fontspec. Fill. isvisible  =     False ;
Mytext. fontspec. Border. isvisible  =     False  ;
  //  Mytext. fontspec. angle = 35;  //  Control text skew  
  Mypane. graphobjlist. Add (mytext );
Start_x  + =     15 ;
}

Mypane. Fill  =     New  Zedgraph. Fill (color. whitesmoke, color. Lavender, 0f );
Mypane. Chart. Fill  =     New  Zedgraph. Fill (color. fromargb (  255  ,  255  ,  245  ),
Color. fromargb ( 255  ,  255  ,  190  ), 90f );
  //  Set the width of the bar  
  Mypane. barsettings. clusterscalewidth  =     30  ;
  //  Bars are stacked  
 Mypane. barsettings. Type  =  Zedgraph. bartype. cluster;

Mypane. xaxis. isvisible  =     False  ;

  //  Enable the X and Y Axis Grids  
  Mypane. xaxis. majorgrid. isvisible  =     False ;
Mypane. yaxis. majorgrid. isvisible  =     True  ;


Mypane. xaxis. Scale. Min  =     -  10  ;
  This  . Zedgraphcontrol_res.resumelayout ();
  This  . Zedgraphcontrol_res.axischange ();
} 

There are several important attributes that need special instructions:

1. // set the width of the bar
Mypane. barsettings. clusterscalewidth = 30;
// Bars are stacked
Mypane. barsettings. type = zedgraph. bartype. cluster;

Setting the width of a bar is only valid for some values in mypane. barsettings. Type (Bar layout setting or type.

2. mytext. fontspec. angle = 35; // control the text skew

3. When mypane. xaxis. isvisible = false, the text below the X axis (usually the value of-y) cannot be displayed.

-- Zedgraph is a foreign control with powerful functions. It may be more convenient or appropriate for me to achieve the effect. I also have a rough understanding of it, hope that our friends will share your experience!
