Self-network implementation of Dual-scale charts in owc)

The line-column chart must be generated. This type does not exist in the chartcharttypeenum Enumeration type of owc. This is dumb, and I feel that I have no way to start. Keep trying, keep searching for information, ah, the consequences of the commitment are really serious, tossing for nearly four hours. At last, it was a bit eye-catching. If you do not specify a type for the entire chart object, you can specify a type for the Series object in the table. First, you can use a series object to draw a bar chart and then add a series object. The specified type is linear. Solve the problem.CodeAs follows:

Using Microsoft. Office. InterOP;
Using owc = Microsoft. Office. InterOP. owc11;
Public partial class default212: system. Web. UI. Page
{
Protected void page_load (Object sender, eventargs E)
{
// Create a chartspace object to place charts
Owc. chartspace objcspace = new owc. chartspaceclass ();

// Whether the legend is displayed
Objcspace. haschartspacelegend = true;

// Add a chart to the chartspace object. The add method returns the chart object.
Owc. chchart objchart = objcspace. charts. Add (0 );

// Specify the chart as a column chart

// Specify the title
Objchart. hastitle = true;
Objchart. Title. Caption = "first-half-year distribution chart ";

// Graph description of X and Y axes
Objchart. Axes [0]. hastitle = true;
Objchart. Axes [0]. Title. Caption = "Y: quantity ";
Objchart. Axes [1]. hastitle = true;
Objchart. Axes [1]. Title. Caption = "X: Month ";

// calculate data
/* categories and values can be represented by a tab string */
string strseriesname = "My tests ";
string strseriesname1 = "Lar ";
string strcategory = "1" + '\ t' + "2" +' \ t' + "3" + '\ t' + "4" +' \ t '+ "5" +' \ t' + "6" + '\ T ';
string strvalue = "9" + '\ t' + "8" +' \ t' + "4" + '\ t' + "10" +' \ t '+ "12" +' \ t' + "6" + '\ T ';
string strvalue1 = "0.038%" + '\ t' + ". 034% "+ '\ t' + ". 039% "+ '\ t' + ". 036% "+ '\ t' + ". 040% "+ '\ t' + ". 033% "+ '\ T';

/* Column chart */
// Add a series
Objchart. seriescollection. Add (0 );
Objchart. seriescollection [0]. type = owc. chartcharttypeenum. chcharttypecolumnclustered;
// Specify the name of a series.
Objchart. seriescollection [0]. setdata (owc. chartdimensionsenum. chdimseriesnames,
+ (INT) owc. chartspecialperformancesenum. chdataliteral, strseriesname );

// Specify a category
Objchart. seriescollection [0]. setdata (owc. chartdimensionsenum. chdimcategories,
+ (INT) owc. chartspecialperformancesenum. chdataliteral, strcategory );

// Specify the value of objchart [0]
Owc. chseries sdispdppm = objchart. seriescollection [0];
Sdispdppm. setdata
(Owc. chartdimensionsenum. chdimvalues,
(INT) owc. chartspecialperformancesenum. chdataliteral, strvalue );

/* Line chart */
// Add another series

Owc. chseries sdisplar = objchart. seriescollection. Add (0 );
Sdisplar. ungroup (true );
Owc. chaxis myaxis = objchart. Axes. Add (sdisplar. get_scalings (Microsoft. Office. InterOP. owc11.chartdimensionsenum. chdimvalues ));
Myaxis. Position = owc. chartaxispositionenum. chaxispositionright;
Myaxis. hasminorgridlines = false;
Myaxis. numberformat = "0.00% ";
Myaxis. hastitle = true;
Myaxis. Title. Caption = "rejection rate (% )";
// Specify the name of a series.
Sdisplar. setdata (owc. chartdimensionsenum. chdimseriesnames,
+ (INT) owc. chartspecialperformancesenum. chdataliteral, strseriesname1 );

// Specify the value of objchart [1]
Sdisplar. setdata
(Owc. chartdimensionsenum. chdimvalues,
(INT) owc. chartspecialperformancesenum. chdataliteral, strvalue1 );

// Ungroup Series
Sdisplar. type = owc. chartcharttypeenum. chcharttypelinemarkers;

// Output as a GIF file.
String strabsolutepath = (server. mappath (".") + "\ temp \ test.gif ";
Objcspace. exportpicture (strabsolutepath, "animated GIF", 600,350 );

// Create the relative path of the GIF file.
String strrelativepath = "./temp/test.gif ";

// Display the image
Image1.imageurl = strrelativepath. tostring ();
