运行情况 添加线段数据在K线图中用线段绘制出来
代码
1 线段标记的数据格式
[[[x0,y0],[x1,y1]],[[x0,y0],[x1,y1]],...]
[x0,y0]和[x1,y1]是线段两个端点的坐标
2 在 Graph_Widget类中 add_marks 方法修改为 def add_marks(self,data:List):# 点曲线区间# 标题,规则,形状,颜色,数据self.del_marks()for row in data:try:rule_str row[1]shape_str row[2]color_str row[3]data_str row[4]data_json json.loads(data_str)if rule_str 点:for node in data_json:targetItem pg.TargetItem(posnode,size20,symbolself.pointshape_map[shape_str],pencolor_str,brushcolor_str,movableFalse)self.pw.addItem(targetItem)self.add_items_list.append(targetItem)passif rule_str 线段:for node in data_json:targetItem pg.LineSegmentROI(positions(node[0],node[1]),pen{color:color_str,width:2},movableFalse)self.pw.addItem(targetItem)self.add_items_list.append(targetItem)passpassif rule_str 连线:for node in data_json:targetItem pg.PlotCurveItem(xnode[0],ynode[1],pencolor_str,symbolself.pointshape_map[shape_str])self.pw.addItem(targetItem)self.add_items_list.append(targetItem)passpassif rule_str 区间:for node in data_json:targetItem pg.LinearRegionItem(valuesnode,pencolor_str,movableFalse)self.pw.addItem(targetItem)self.add_items_list.append(targetItem)passpassexcept Exception as e:print(e)continuepasspass
3 在SettingMarksWidget 类中
init_data 方法 def init_data(self):self.please_select_str: str -- 请选择 --self.rule_map: Dict {点:数据格式提示:[[x,y],[x,y],...],线段:[[(x0,y0),(x1,y1)],[(x0,y0),(x1,y1)],...],连线:数据格式提示:[[x_list,y_list],...],区间:数据格式提示:[[x0,x1],[x0,x1],...]}self.no_pointshape_rules_list: List [线段,区间]self.pointshape_map: Dict {圆:o,三角形:t,星形:star,正方形:s,菱形:d,加号:,向下箭头:arrow_down,向左箭头:arrow_left,向上箭头:arrow_up,向右箭头:arrow_right}pass
rule_combox_currentTextChanged 方法 def rule_combox_currentTextChanged(self,txt:str):cur_txt self.rule_combox.currentText()if not cur_txt or cur_txt self.please_select_str:self.rule_label.setText()returnself.rule_label.setText(self.rule_map[cur_txt])if cur_txt in self.no_pointshape_rules_list:self.pointshape_combox.setCurrentText(self.please_select_str)self.pointshape_combox.setDisabled(True)else:self.pointshape_combox.setDisabled(False)pass
