uc gui如何动态显示一根曲线

uc gui如何动态显示一根曲线

代码张贴如下:
其中关键是:

GRAPH_DATA_YT_AddValue(hData,50);

for(a = 0; a< 100; a++)
{
GRAPH_DATA_YT_AddValue(hData,a + 10);
}
我该如何才可以绘制出一条简单的曲线呢?
#include "GUI.h"

#include "GUIDEMO.h"

#include "GRAPH.h"

GRAPH_DATA_Handle hData;

GRAPH_SCALE_Handle hScale;

I16 m = 50;

I16 *aData0 = &m;

WM_HWIN hGraph;

WM_HWIN hWM_HBKWIN;



static void _cbBk(WM_MESSAGE * pMsg) {

static unsigned int GirdFlag = 0;

switch (pMsg->MsgId) {

case WM_PAINT:

// GUIDEMO_DrawBk(1);

break;

case WM_TOUCH:

GirdFlag++;

GRAPH_SetGridVis(hGraph,GirdFlag%3); //!< Display the if touch the screen

break;

default:

WM_DefaultProc(pMsg);

}

}

void MainTask(void) {

int a = 0;

GUI_Init();

//!< Create a window as desktop

hWM_HBKWIN =

WM_CreateWindow(5,5,380,230,WM_CF_SHOW,0,0);

// Set Callback function for background window

WM_SetCallback(hWM_HBKWIN, _cbBk);

WM_SetDesktopColor(GUI_BLUE); //!< SetDesktopColor

//!< Create a graph widget

hGraph = GRAPH_CreateEx(30, 15, 300, 200, hWM_HBKWIN, WM_CF_SHOW, 0, 100);

//GRAPH_DATA_YT_MirrorX(hGraph , 1);

//!< Create a YT_data

hData = GRAPH_DATA_YT_Create(GUI_RED, 10, aData0, 10);

GRAPH_DATA_YT_AddValue(hData,50);

for(a = 0; a< 100; a++)

{

GRAPH_DATA_YT_AddValue(hData,a + 10);

}

hScale = GRAPH_SCALE_Create(28, GUI_TA_RIGHT, GRAPH_SCALE_CF_VERTICAL, 20);

GRAPH_AttachScale(hGraph, hScale);

GRAPH_SetGridDistX(hGraph,20);

GRAPH_SetGridDistY(hGraph,20);

GRAPH_SetGridVis(hGraph,1); //!< Display the Grid

GRAPH_SetBorder(hGraph,30,5,5,5); //!< Set the frame border

GRAPH_AttachData(hGraph, hData); //!< Attach the data to graph

while(1) {

// GUIDEMO_main();

GUI_Exec();

// OSTimeDlyHMSM(0,0,0,100);

}

}

GRAPH_DATA_YT_AddValue(hData,50); for(a = 0; a< 100; a++) { GRAPH_DATA_YT_AddValue(hData,a + 10);

你好！ GRAPH_DATA_YT_AddValue(hData,50); for(a = 0; a< 100; a++) { GRAPH_DATA_YT_AddValue(hData,a + 10); 仅代表个人观点，不喜勿喷，谢谢。
