How do I graph two trendlines on one graph?
显示 更早的评论
I can plot two data sets on graph, however when I go to add a trend line, I can only do so for one data set. I need to be able two add a trend line for both data sets. So my plot will have to data sets and two trendlines.
Thanks guys,
Bobby

Are you referring to some special tool or just to normal plotting? In the first case, which tool? In the second case, why are you not able to plot two trendlines? Here, I use smooth() as trendline:
x=linspace(0,10);
y1=(x+rand(size(x))).^2;
y2=(10-x+rand(size(x))).^2;
figure, plot(x,y1,x,y2)
sy1=smooth(y1);
sy2=smooth(y2);
hold all
plot(x,sy1,'k',x,sy2,'k')
-> works.

Try using the command hold on and plot the other trendline. (Type help hold on in the command window for description)
