# 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):

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.

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