Trouble with displaying gra

Here is my code:

A = load('Data.txt');
histogram(A)
scatterplot(A)
boxplot(A)

(A is a text file of 20 random numbers.)

I need Matlab to show all three of the diagrams, but it only shows two. I am totally new at Matlab, and I have no clue what is incorrect about this code. Anyone know what I did wrong?

A = load('Data.txt');
subplot(1,3,1);
histogram(A)
subplot(1,3,2);
scatterplot(A)
subplot(1,3,3)
boxplot(A)

It still only pulled up two windows... however this time it displayed the histogram and boxplot. Alongside the histogram it brought up a blank table.

You appear to be using scatterplot() from the Communications Systems toolbox. It is restricted to using its own figure, not to using the current axes.

A = load('Data.txt');

fig = figure(1);
ax1 = subplot(1,2,1, 'Parent', fig);
histogram(ax1, A);
title('histogram')
ax2 = subplot(1,2,2);
boxplot(ax2, A);
title('boxplot')

fig2 = figure(2);
scatterplot(A)
title('scatterplot')

If the scatterplot comes up empty, it could be that your data is not very suitable for a scatterplot

[Kenneth May]

That did the trick. Oddly enough, it now brings up three separate figures, one of which is blank, but all of the information is there.

Thanks!

Remove the fig2 = figure(2) call. I was not sure that scatterplot would create a figure when it had an existing empty figure.
