plot_slope_2D

pySurf.data2D.plot_slope_2D(wdata, x, y, scale=(1.0, 1.0, 1.0), vrange=None, srange=None, filter=False)

use calculate_slope_2D to calculate slope and plot map and slice slope rms in x and y. Return the three axis. Set scale to (1,1,1000.) for z in micron, x,y in mm. If filter is set, data out of srange are removed and automatic scale is

used for plot. If not, srange is used for plot axis, but all data are used in plots and rms calculation.
