Hello!
I'm trying to plot a 3D dataset as a scatter-plot, coding Z-axis values
with point size. I pass the following parameters to "plot" function:
type = 'p',
pch = 16,
cex = intensity/max(intensity)
In my dataset, max(intensity)/min(intensity) is ~4000. However, visual
points vary in radius by no more then 100 probably. Albeit default
device isn't good at displaying micro-points, other devices (pdf, svg)
can display such points just fine.
Is there a way to produce micro-points with cex=0.001 and less?
Hi Andrey,
As the points help page says:
What happens for very small or zero values of cex is device-dependent:
symbols or characters may become invisible or they may be plotted at a
fixed minimum size.
Indeed, for svg device micro-points are plotted at fixed minimal size.
But is there a way to work-around this limitation, for svg device?
Best wishes,
Andrey Paramonov
