(Newbie here) Accessing IBM Q Experience on a Windows 7 operating system and using the Google Chorme browser. I can completely assemble my circuit, using the IBM Quantum Composer and when executing it goes to the area job, I hope to finish the whole process, but when I press to see the results, only what appears in the image appears, I can't go down the page for the histogram presentation, however when accessing the same Job tab via my cell phone, the histogram and the circuit that was shown appear.

    $\begingroup$ @jyu00 Can you submit a circuit to the hardware without measurement? $\endgroup$

  • $\begingroup$ I believe I already saw this error with another user, his antivirus was blocking this somehow and by disabling it and configuring it another way it worked, maybe you could try that? $\endgroup$

  • $\begingroup$ @KAJ226 Yes you can submit a circuit without measurement. I don't remember why people would want to do that though. $\endgroup$

    $\begingroup$ @Lena Thank you, this solution worked, both the histograms and the circuit came back to me in the job tab $\endgroup$

Strange.

This offers a way for you to retrieve your histogram but not exactly the solution to your problem. So hopefully it will be useful somehow.

First, note that each job you submitted has a job_ID. You actually can see it on the top left of your screenshot. You can "copy and paste" this JobID into line 6 of the script below

from qiskit import IBMQ
from qiskit.visualization import plot_histogram
%matplotlib inline
provider = IBMQ.load_account()
backend = provider.get_backend('ibmq_santiago')
job = backend.retrieve_job('ENTER JOB_ID HERE')
counts = job.result().get_counts()
plot_histogram(counts, color='black', title="Result")

Executing this script through the Jupyter Notebook provided in Quantum Lab will print out your Histogram. For instance, using a JobID for one of my old job, I printed out the following.

Again, not the exact solution to your question but at least this should provide you a way to retrieve your result, plot it, and not wasting your time having to rerun your experiment to get a new plot.
