Box plot with log axis results in log-scaled box widths

Originally reported in plotly/plotly.py#1415

When plotting a box plot on a log axis, the box widths seem to follow the log pattern.

var y0=[],y1=[]
for ( i = 0; i < 50; i ++) 
{
	y0[i] = Math.random();
	y1[i] = Math.random();
}

var trace1 = {
	x: y0.map(v => 1),
   y: y0,
  type: 'box'
};

var trace2 = {
  x: y0.map(v => 10),
  y: y1,
  type: 'box'
};

var trace3 = {
  x: y0.map(v => 100),
  y: y1,
  type: 'box'
};

var data = [trace1, trace2, trace3];
var layout = {xaxis: {type: 'log'}}

Plotly.newPlot('myDiv', data, layout, {showSendToCloud: true});

Since the width of the boxes is not a value in data coordinates, it seems to me that we shouldn't scale it according to the log axis transform. What do you think?

It would be really useful to input a box width in pixel. So it would be possible to output plots with different axis scales but same look. Don't know how to achieve this at the moment.

Maybe try the new box width attribute added in #3234

Thanks @jonmmease I never tried plotting a box trace on a log position axis. Good to know!

I fixed this issue in s417-lama#1 .
