Overall looks good to me! My question is why the HTTPS Overview visualisations are not drawing the lines but just the dots. Is any special setting missing from these TSVBs?

[kaiyan-sheng]

@ChrsMark Thanks for the review! HTTPS overview is showing dots instead of lines not because of TSVB, it's because the real data I collected from GCP is sparse and not every collection period, there is data points available 😞 If one day I got better data points, I will definitely update the screenshots 😄
