hi, I have variables with data, like

x= 20,12,15,65,74,52,233
y=55,2,221,23,21,21,11

I have done a scatter plot and added a trade line to it, but I want to plot that to some specific level of x axis. For example I want to set the maximum level of x to 70 and scatter plot it and add a trend line up to that value. How can I do that?

here is my code.

scatter( x, y, 'filled','LineWidth',1.5)
p = polyfit(x, y, 1);
px = [min(x) max(x)];
py = polyval(p, px);
scatter(x, y  'filled')
hold on
plot(px, py, 'LineWidth', 2);
