-Jx

xscale[/yscale] (Linear scale(s) in distance unit/data unit).

-Wbin_width[+l|h|b]

Sets the bin width used for histogram calculations. The modifiers specify the handling of extreme values that fall outside the range set by -R. By default these values are ignored. Use +b to let these values be included in the first or last bins. To only include extreme values below first bin into the first bin, use +l, and to only include extreme values above the last bin into that last bin, use +h.

table

One or more ASCII (or binary, see -bi[ncols][type]) data table file(s) holding a number of data columns. If no tables are given then we read from standard input.

-A

Plot the histogram horizontally from x = 0 [Default is vertically from y = 0]. The plot dimensions remain the same, but the two axes are flipped.

-B[p|s]parameters (more ...)

Set map boundary frame and axes attributes.

-Ccpt

Give a CPT. The mid x-value for each bar is used to look-up the bar color.

-D[+b][+ffont][+ooff][+r]

Annotate each bar with the count it represents. Append any of the following modifiers: Use +b to place the labels beneath the bars instead of above; use +f to change to another font than the default annotation font; use +o to change the offset between bar and label [6p]; use +r to rotate the labels from horizontal to vertical.

-F

Center bin on each value. [Default is left edge].

-Gfill

Select filling of bars [Default is no fill].

-I[o|O]

Inquire about min/max x and y after binning. The xmin xmax ymin ymax is output; no plotting is done. Append o to output an ASCII table of the resulting x,y data instead. Upper case O will output all x,y bin data even when y == 0.

-Jz|Zparameters (more ...)

Set z-axis scaling; same syntax as -Jx.

-K (more ...)

Do not finalize the PostScript plot.

-Lpen

Draw bar outline using the specified pen thickness. [Default is no outline].

-N[mode][+ppen]

Draw the equivalent normal distribution; append desired pen [0.5p,black]. The mode selects which central location and scale to use:

The -N option may be repeated to draw several of these curves.

-O (more ...)

Append to existing PostScript plot.

-P (more ...)

Select "Portrait" plot orientation.

-Q

Draw a cumulative histogram.

-Rxmin/xmax/ymin/ymax[+r][+uunit] (more ...)

Specify the region of interest.

-S

Draws a stairs-step diagram which does not include the internal bars of the default histogram.

-U[[just]/dx/dy/][c|label] (more ...)

Draw GMT time stamp logo on plot.

-V[level] (more ...)

Select verbosity level [c].

-Y[a|c|f|r][y-shift[u]] (more ...)

Shift plot origin.

-Z[type][+w]

Choose between 6 types of histograms:

To use weights provided as a second data column instead of pure counts, append +w.

-bi[ncols][t] (more ...)

Select native binary input. [Default is 2 input columns].

-dinodata (more ...)

Replace input columns that equal nodata with NaN.

-e[~]"pattern" | -e[~]/regexp/[i] (more ...)

Only accept data records that match the given pattern.

-f[i|o]colinfo (more ...)

Specify data types of input and/or output columns.

-h[i|o][n][+c][+d][+rremark][+rtitle] (more ...)

Skip or produce header record(s).

-icols[+l][+sscale][+ooffset][,...] (more ...)

Select input columns and transformations (0 is first column).

-p[x|y|z]azim[/elev[/zlevel]][+wlon0/lat0[/z0]][+vx0/y0] (more ...)

Select perspective view.

-t[transp] (more ...)

Set PDF transparency level in percent.

-^ or just -

Print a short message about the syntax of the command, then exits (NOTE: on Windows just use -).

-+ or just +

Print an extensive usage (help) message, including the explanation of any module-specific option (but not the GMT common options), then exits.

-? or no arguments

Print a complete usage (help) message, including the explanation of all options, then exits.
