Boxplot with double y-axis
显示 更早的评论
Hello All, I want to plot a boxplot with a double y-axis (reference figure is attached). Actually, I have two sets of variables. One variable value will display on the left side and another variable value will display on the right of the y-axis.

The idea is to create empty box plots.
load carsmall
yyaxis left
boxplot([Acceleration nan(100,1)])
yyaxis right
boxplot([nan(100,1) Horsepower])
You can see that [Acceleration nan(100,1)] creates a 100x2 matrix with second column as nan.
- When I use boxplot for left axis, it plots two curves at x-location 1 and 2 for each column. As the second column is nans, second boxplot is empty.
- Now, for second plot, I want location-1 to be empty (as I already have plotted acceleration on that), so I use [nan(100,1) Horsepower], which will draw Horsepower at x-location 2.
For your refereimage, you will need to do something like this
yyaxis left
boxplot([l1 nan(100,1) l2 nan(100,1) l3 nan(100,1)])
yyaxis right
boxplot([nan(100,1) r1 nan(100,1) r2 nan(100,1) r3])
This is not what you are looking for but I think closest:
- The colors need to be tackled. You can change individual colors as shown here
- Labels need to be tackled

Hi,
The key idea is to activate the axis that you want to plot. Suppose I have two ys : y1 and y2, I want to plot y1 on the left side and y2 on the right side, I can do as shown here:
yyaxis left
plot(x,y1);
yyaxis right
plot(x,y2);
You can read more about it at the example shown here.

I think it is working as intended, as there are two boxplots at the same 'x'.
A simple example is here
load carsmall
yyaxis left
boxplot(Acceleration)
yyaxis right
boxplot(Horsepower)
What you are looking for is a no superposition.
