How to change corrplot line and scatter dots properties?

Hi Eveyone,

I would like to change the properties of corrplot, like linewidth or color of the dot. How can I do that?

Also, is there any way to save only 1 plot in corrplot?

Thank you

Get the handle of the plot out and modify the desired properties:

[~,~,h] = corrplot(rand(100,2))

h = 
  2×2 graphics array:

    Histogram    Line     
    Line         Histogram

h(1,2)

ans = 
  Line with properties:

              Color: [0 0 1]
          LineStyle: 'none'
          LineWidth: 0.5000
             Marker: 'o'
         MarkerSize: 2
    MarkerFaceColor: 'none'
              XData: [0.7873 0.5984 0.1201 0.1410 0.0083 0.1620 0.1182 0.1570 0.2894 0.5865 0.7984 0.4431 0.4161 0.4538 0.1486 0.1437 0.5509 0.3145 0.3455 0.3906 0.1897 0.6107 0.6898 0.6438 0.1894 0.7857 0.7490 0.6415 0.6582 0.0314 0.0351 0.4634 … ]
              YData: [0.2229 0.0350 0.4146 0.1456 0.0748 0.7509 0.7659 0.5506 0.1790 0.0956 0.3297 0.8241 0.6540 0.7515 0.1818 0.0070 0.3617 0.7087 0.3328 0.4187 0.6542 0.4051 0.7642 0.8023 0.5341 0.5813 0.8490 0.2850 0.8221 0.7120 0.4635 0.3704 … ]

  Show all properties

h(1,2).Color = 'r';
h(1,2).MarkerSize = 4;

The regression line's handle can be found as:

h(1,2).Parent.Children

ans = 
  3×1 graphics array:

  Text    (corrCoefs)
  Line    (lsLines)
  Line

L = h(1,2).Parent.Children(2);
L.LineWidth = 3;
