make linear plot
eplot ([xData,[yData,[legendText,[dash,[color[,width]]]]]])
xData :
vector of x-data
or matrix(2xn) of x0,x1-data to plot lines
yData :
vector of y-data
or matrix(2xn) of y0,y1-data to plot lines
legendText :
text of legend, if empty string then no legend
dash :
if a scalar and
dash=0 solid plot line,
dash>0 dash length
dash<0 fill plot line with color
default: dash=eLineDash
if a vector with size 1xn, then dash describes
a dash combination [space lineLength1 lineLength2 ...]
if a string then dash is a name of symbol
if a matrix and color=-1
dash is the image of plot
and filled with RGB values
(value=R*2^16+G*2^8+B and R,G,B are integer of 0:255)
if a matrix and color is a colormap
dash is the image of plot
and filled with indices of colormap
if a string dash is filename of a JPEG-file
color :
if dash>=0 vector of plot color ([r g b])
if dash<0 vector of background color
if dash a matrix then colormap of image or -1
default: dash=eLineColor
width :
width of plot line
Important: :
eplot without parameters closes the current plot explicit.
it’s useful for several plot on one page
