Axis macro in MetaFun

["kauśika cittūr via ntg-context" <ntg-context@ntg.nl>]

Dear All,

I am truly grateful for the new additions to MetaFun. It has greatly helped me 
in producing neat drawings for my academic work. In this connection, I have a 
few queries.

Currently I am using PGFPlots (with ConTeXt) to draw simple plots from CSV 
data. I was wondering if there is any way to do the same in MetaFuns. That is, 
is it possible to do something like the following in order to obtain a line 
plot of the values in the 'data.csv' file? Also is it possible to have the 
'labels' be the identical for all points in a given list? 

\startMPcode
  draw lmt_axis [
      sx = 2mm, sy = 2mm,
      nx = 80, ny = 40,
      tx = 15, ty = 15, 
      
      list = {
            [
                  connect = true,
                  color = "darkblue",
                  close = true,
                  points = {data.csv},
                  labels = {"•"},
            ]
      },
  ] withpen pencircle scaled 0.5mm;
\stopMPcode

My final query: is it possible to specify a co-ordinate transform for any/all 
of the axes? For instance in my work, I would like to plot the y-axis in the 
log-scale.

Thanks,
kauśika
