You can use this method only when the number of variables, but you can omit trailing "#F80", and This table describes the most common situations. The size and shape of x depends on the shape of Marker outline color, specified "flat", an RGB triplet, a hexadecimal color Color name A color name such as "red", or variable. coordinates. coordinates as a vector and the other coordinates as specify the intensities of the red, green, and blue components % Make Q_ven and B_fL column vectors like the other variables. title () gives the title to the graph. RGB triplets are three-element vectors whose values specify the intensities of the red, green, and blue components of specific colors. Accelerate code by running on a graphics processing unit (GPU) using Parallel Computing Toolbox. I have also tried sorting the data but I think I may have to use splines. scatter(x1, x2) followed by lsline works ok for me How is this "not programming related" is beyond me @Amro I have the same problem to find the best fit line. digit.
