MakeTDmap
class fisspy.analysis.tdmap.makeTDmap(data, dx=1, dy=1, dt=1, cmap=None, figsize=None, dpi=100, clim=None, label=None, aspect=1/10)
Description: Make Time-Distance map for given slit position interactivelyParameters
- data (numpy.ndarray) - 3-dimensional data array with the shape of (nt, ny, nx).
- dx (float, optional) - Pixel scale along x-axis in the unit of km.
- dy (float, optional) - Pixel scale along y-axis in the unit of km.
- dt (float, optional) - Pixel scale along t-axis in the unit of sec.
- cmap (matplotlib color map, optional) - Colormap of the image.
- figsize (list, optional) - Figure size.
- dpi (int, optional) - Depth per inch.
- clim (list, optional) - Color limit of the image.
- label (str, optional) - Label of the figure.
- aspect (float, optional) - aspect of the figure slope of the TDmap ((km/s)^-1). Default is 1/10.
Returns
- Make TDmap object
Note: To use the function correctly, you should change the backend of the matplotlib from inline to any of interactive backend (see here). In IPython you can simply change the backend by using '%matplotlib' magic function.
