Is there a way to extract the x data values from the readWaveform function in Quick-Control Oscilloscope ?

I need to extract the time values as well which is the x-axis data. I am currently using the DPO4014B oscilloscope from Tektronix. I've also tried installing the ivi driver but im not sure how to use the function to read the waveform.

Currently you need to generate the waveform time values by using AcquisitionTime and WaveformLength properties. For example, if o is your oscilloscope object:
y1 = readWaveform(o);
t = linspace(0, o.AcquisitionTime, o.WaveformLength);
figure
plot(t, y1)
xlabel('Time (s)')
ylabel('Voltage (V)')
You might also find the following example app useful:
