Charts: reverse order Y axis values (highest to lowest)

[arikfr]

This to support a chart similar to this one: (where 1 is at the top)

[arikfr]

@kravets-levko does Plot.ly support this?

[kravets-levko]

@arikfr Plotly supports this, but with strange limitations. It has autorange: True | False | 'reversed' config, but it works only for automatic ranges. When min/max or axis type is specified - autorange is ignored.

[arikfr]

At first I was confused why they coupled those settings, but then I realized: if you set max=0 and min=10, you get this:

So it actually makes sense. In its own way :-)

[arikfr]

Also I just noticed we have a "Reverse Order" button that seems to do nothing. Is it controlling this autorange setting or it's something else?

[kravets-levko]

@arikfr Currently "Reverse Order" (for X axis) is implemented on our own, so it works when X axis type is not "Auto" (at least, it should work this way)

[kravets-levko]

but then I realized: if you set max=0 and min=10, you get this:

But if you don't set min or max, it gets broken (compare settings and results):

So even if it makes some sense - it does not cover all settings combinations 🙂

Update about "Reverse Order" for X axis: it works only when type is explicitly set to "Category" - this feature was introduced in #2080

I was referring to the setting for Y Axis.

Ah. That setting works only for Heatmap charts and should be hidden for other types. This is already fixed in React version of chart editor.
