Hi I have this dataset ' pima-indians-diabetes' have 8 features with 2 classes (0 and 1)

and I wanna do svm and csvm on the third and sixth features but I can not draw the line and just plot support vectors

this is my code right now

clc

clear all

close all

datas = csvread('pima-indians-diabetes.csv');

f3=datas(1:1:768,3);

f6=datas(1:1:768,6);

X=[f3 f6];

Y=datas(1:1:768,9);

SVMModel = fitcsvm(X,Y)

sv = SVMModel.SupportVectors;

figure

gscatter(X(:,1),X(:,2),Y)

hold on

plot(sv(:,1),sv(:,2),'ko','MarkerSize',10)

legend('1','0','Support Vector')

hold off

and is fitcsvm is svm or csvm?if its csvm how to define c and if its not what sholud I use instead?
