画股票分析图

图中的x,y轴代码为：
public void drawAxis(Canvas canvas) {
paint.setColor(Color.YELLOW) ;
paint.setStrokeWidth(2) ;
canvas.drawLine(30, 300, 310, 300, paint) ;
canvas.drawLine(30, 20, 30, 300, paint) ;

int x = 90 ;
int y = 250 ;

for (int i = 0; i < 4; i++) {
canvas.drawText(i + 1 + "", x, 320, paint) ;
x += 60 ;
}
for (int i = 0; i < 5; i++) {
canvas.drawText(50 * (i + 1) + "", 0, y, paint) ;
y -= 50 ;
}
}
曲线代码：
public void drawHighLines(Canvas canvas) {
int[][] highPoints = new int[4][2] ;
highPoints[0][0] = 90 ;
highPoints[0][1] = data_total[0] ;
highPoints[1][0] = 150 ;
highPoints[1][1] = data_total[1] ;
highPoints[2][0] = 210 ;
highPoints[2][1] = data_total[2] ;
highPoints[3][0] = 270 ;
highPoints[3][1] = data_total[3] ;
paint.setColor(Color.RED) ;
for (int i = 0; i < 4; i++) {
canvas.drawPoint(highPoints[i][0], 300 - highPoints[i][1], paint) ;
canvas.drawText(data_total[i] + "", highPoints[i][0] - 10, 300 - highPoints[i][1] - 10,
paint) ;
}

float[] pts = new float[16] ;
for (int i = 0; i < 12; i++) {
pts[0] = 32 ;
pts[1] = 300 - highPoints[0][1] ;
pts[2] = highPoints[0][0] ;
pts[3] = 300 - highPoints[0][1] ;
pts[4] = highPoints[0][0] ;
pts[5] = 300 - highPoints[0][1] ;
pts[6] = highPoints[1][0] ;
pts[7] = 300 - highPoints[1][1] ;
pts[8] = highPoints[1][0] ;
pts[9] = 300 - highPoints[1][1] ;
pts[10] = highPoints[2][0] ;
pts[11] = 300 - highPoints[2][1] ;
pts[12] = highPoints[2][0] ;
pts[13] = 300 - highPoints[2][1] ;
pts[14] = highPoints[3][0] ;
pts[15] = 300 - highPoints[3][1] ;
}
canvas.drawLines(pts, paint) ;
}
第一副图两条柱子代码：

paint.setColor(Color.GREEN) ;
int temp_screen = 30 ;
for (int i = 0; i < 4; i++) {
chart.setH(data_screen[i]) ;
chart.setX(temp_screen + 20 * 2 + margin) ;
chart.drawSelf(canvas, paint) ;
margin = 20 ;
temp_screen = chart.getX() ;
}

margin = 0 ;

paint.setColor(Color.BLUE) ;
int temp_power = 50 ;
for (int i = 0; i < 4; i++) {
chart.setH(data_power[i]) ;
chart.setX(temp_power + 20 * 2 + margin) ;
chart.drawSelf(canvas, paint) ;
margin = 20 ;
temp_power = chart.getX() ;
}

drawHighLines(canvas) ;

第二个图柱子代码
paint.setColor(Color.GREEN) ;
int temp = 40 ;
for (int i = 0; i < 4; i++) {
chart.setH(data_total[i]) ;
chart.setX(temp + 20 * 2 + margin) ;
chart.drawSelf(canvas, paint) ;
margin = 20 ;
temp = chart.getX() ;
}
