TFSA PLOTTING FACILITIES Plotting routines used to visualise data. The following types of graphs can be employed: (i) Plot (ii) Image (iii) Pseudo-Colour (iv) Waterfall (1 and 2) (v) Mesh (vi) Surf (vii) Contour (viii)TFSAPL All plots except (i) can be used to plot time-frequency distributions. The time domain and frequency spectra one dimensional plots can be added to the figure along the two axes. The plots can be configured by specifying various options in the figure. The 'Expand' button can be used to reveal more options. On the actual plot figure the appearance of the plots can be altered from a popup menu which is activated by right clicking. EXPLANATION OF VARIOUS PLOTTING ROUTINES (i) Plot Used for one dimensional plots of signals, IF estimation, wavelet coefficients, frequency spectra etc. (ii) Image Used to plot two dimensional matrices such as time-frequency distributions and scalograms. Displays the matrix as an image. (iii) Pseudo-Colour Pseudo-colour plots a colour grid for each element of the input matrix. Also used to plot two dimensional matrices such as time-frequency distributions and scalograms. (iv) Waterfall 1 and 2 Again also used to plot two dimensional matrices such as time-frequency distributions and scalograms. This uses a waterfall style plot of the matrix, using different viewing angles which distinguish Waterfall 1 and Waterfall 2. (v) Mesh Same as the waterfall plots except that column lines are drawn to produce a 'mesh' surface. (vi) Surf Equivalent to the mesh plot except that a 'surface' is now defined over the mesh. (vii) Contour Contour plot of the two dimensional matrix where the different coloured lines represent varying degrees of magnitudes. (viii) TFSAL TFSA graphing function specifically optimised for viewing time-frequency distributions. See Also: tfsapl
