现在，我想单击角落并将值存储到新数组中。我想旋转通过单击创建的新数据集。但是在旋转它们时，似乎反向旋转不起作用。这是代码：

output_file("callback.html")

plot = figure(plot_width=400, plot_height=400)
plot.toolbar.logo = None
tapX = []
tapY = []
tools = "pan,wheel_zoom,reset,hover"
data = {'x_values': ld2.x,
        'y_values': ld2.y}

source = ColumnDataSource(data=data)
print(data)
source1 = ColumnDataSource(data=dict(x=tapX, y=tapY))
lidarPlot= plot.circle(x='x_values', y='y_values',hover_color="red", source=source)

customPlot= plot.scatter('x', 'y', source=source1,
             line_color='red', fill_alpha=0.6, size=10)
plot.patch('x', 'y',source=source1, line_width=5, color="red", alpha=0.2)
draw_tool = PointDrawTool(renderers=[customPlot])

callback = CustomJS(args=dict(sensor=source, xy=source1 ), code="""

        // getting lidar value and tabX & tapY
        console.log("start")

        var sensorData = sensor.data;
        console.log(sensorData)       
        var a = sensorData['x_values'];
        var b = sensorData['y_values'];
    """)

callbackForRotation = CustomJS(args=dict(xy=source1 ), code="""                     console.log("end")

        var data = xy.data;
        var x = data['x'];
        var y = data['y'];
        // getting slider value
        var rotationAngle = cb_obj.value;        
        var radians = (Math.PI / 180) * rotationAngle;
        console.log("radians", radians); 
        cos = Math.cos(radians);
        sin = Math.sin(radians);
        cx=2;
        cy=2;
        if(cb_obj.x) {    
                x.push(cb_obj.x);
                y.push(cb_obj.y);
                console.log(cb_obj.x);
            }
        if(x.length> 0 && radians) {
            for (var i = 0; i < x.length; i++) {
                x[i] = (cos * (x[i] - cx)) + (sin * (y[i] - cy)) + cx,
                y[i] = (cos * (y[i] - cy)) - (sin * (x[i] - cx)) + cy;
            }
        }
        xy.change.emit();
        """)

rotation = Slider(start=-180, end=180, value=0, step=0.1, title="Rotate ")
#callback.args["slider"] = rotation   # sending slider value into the callback function
rotation.js_on_change('value', callbackForRotation)
plot.js_on_event('tap', callbackForRotation)
layout = column(rotation, plot)   # create two row, 1. rotation 2. plotting
plot.add_tools(draw_tool)
plot.toolbar.active_tap = draw_tool
show(layout)

问题是什么？我该如何解决？
