Why do I keep getting "ValueError: x and y must have same first dimension, but have shapes (999953,) and (999952,)" using pyvisa and matplotlib

here is the code sample, ive been using matplotlib and pyvisa

try:
    tex = tektronixOscope(source)
    print("Getting offsets...")
    tex.getOffsets()
    armed   = tex.armed
    auto    = tex.auto
    ready   = tex.ready
    save    = tex.save
    trigger = tex.trigger

    print("Checking trigger status...")
    state = tex.checkTrigger()

    plt.ion()
    fig = plt.figure()

    triggerCount = 0
    checkCount = 1
    # start = Time.time()
    # while((Time.time()-start) > 30):
    while(True):
        if(tex.state == tex.trigger):
            triggerCount+=1
            print ("Scope has triggered %d/%d, reading out data now" % (triggerCount,checkCount))
            print (tex.readData())
            [time,volts] = tex.unpackData()
            plt.plot(time,volts)
            plt.show()
            plt.pause(0.0001)

.....

def unpackData(self):
       headerlen = 2 + int(self.data[1])
       header = self.data[:headerlen]
       ADC_wave = self.data[headerlen:-1]

       ADC_wave = np.array(unpack('%sB' % len(ADC_wave),ADC_wave))

       self.volts = (ADC_wave - self.yoff)*self.ymult + self.yzero
       self.time = np.arange(0,self.xincr*len(self.volts),self.xincr)

       return [self.time,self.volts]

The problem with this code, is that it constantly gives me the following error message:

"x and y must have same first dimension, but have shapes (999953,) and (999952)

I have checked the equations multiple times but I still don't understand what is wrong. have looked into questions with a similar problem but im still unable
