Dear All,

I have got a data set, which has one independent variable (x) and two dependent variables(y1 and y2). I want to plot the data set in one figure as given below and *finally want to flip the y axis related to y2 up side down***.

Experts please help me out

x=1:10;
y1=x.*x;
y2=5*x+3;
figure();
scatter(x,y1,50,'.','r');
hold on;
bar(x,y2,'g')

Use plotyy(), saving the handles. Choose the one of choice to set the y-axis direction on.

I hope this is what you had in mind. To make sense of it, I think you need to display 2 Y-axis, the example below does that.

    figure();
    bar(x,y2,'g');
    set(gca,'ydir','reverse');
    ax1=gca; 
    set(ax1,'YColor','g'); axis([0 11 0 100])
    ax2 = axes('Position',get(gca,'Position'), 'YAxisLocation','right', 'Color','none', 'YColor','r');
    hold on;
    scatter(x,y1,50,'.','r');
    set(ax1,'YColor','g'); axis([0 11 0 100])
