EMT – Version 2014-03-03

This version features some changes in the plot routines. First of all, there is now an easy way to use GnuPlot. I posted an example in the previous announcement. Here is another one.

>&plot3d(atan(-x^2+y^3/4),[x,-4,4],[y,-4,4],[grid,50,50],[gnuplot_pm3d,true]):

Here is the same plot in EMT. I changed the default colors for grids and labels to a decent dark gray.

plot3d("atan(-x^2+y^3/4)",r=4,angle=35°,>spectral,n=100,grid=20):

test-002

It is also possible to insert images from MatPlotLib into the notebook. For examples, see the home page of EMT.

The axis labels and the axis commands got some update too. The y-label is now vertical by default, and the numerical ticks can be made vertical with vertical=2. The new style grid=6 looks makes small ticks on the sides and no grid lines.

Changes-006

The xaxis() and yaxis() commands got new features. By default, they produce small ticks.

Changes-007
