[Scilab-users] 2D Density plot

[arctica1963]

Hello all,

I was wondering if it is possible to generate a 2D density plot from
scattered data to highlight areas with a higher concentration of points
compared to others?

<http://mailinglists.scilab.org/file/t495709/Subsidence_plot.png> 

The image shows a subsidence plot with theoretical curves and real data
overlaid. It would be nice to have a way to colour the density of points,
but leave areas with zero density blank. 

In GIS software (e.g. ArcMap or QGIS) this would be defined using a
"Heatmap" based on a search radius around each data point.

Any ideas?
Thanks
