small domain does not display correctly.

In this codepen, the first attempt on Plotly.newPlot is not working.

I have two Y-axes. The bottom has a domain of [0,0.5], while the second has the plot_layout.yaxis2.domain = [0.945, 0.95]. However, the second Y-axis will overlap the whole plot. I expected it only covers the top 94.5% to 95%. I don’t know why this does not work. If I simply change the domain to [0.94, 0.95] covering top 94% to 95%, it suddenly worked. Why does this happen?

I’ll leave the issue open, as it probably would be good to tighten up this limit.

Why do you want to avoid “almost zero” values?

I think we wanted to avoid errors if we round some size to zero and end up making invalid svg elements. Perhaps we should take the height or width into account, and refuse any domain smaller than 1px.

And I cannot find the 0.01 buffer in the CDN?

It’s going to be hard to find something like that in minified code, but since you’re seeing this effect I’m quite sure it’s there somewhere!
