Plotting very small and large values on same figure.

Hi, I have one question. I have set of data column wise. Actually two columns are there. Problem is that 1 column contain very small values in decimals like 0.00001 etc where the other column has comparatively large values. I want to analyze this data through plotting.

Can anybody please suggest me which plot type like bar, scatter or plot is better here??? I would be very thankful to you.

Maybe a plot with 2 y axis is helpful - you could check yyaxis in the documentation

can you help me with syntax

[Stephan]

Check the examples - it is really easy: https://de.mathworks.com/help/matlab/ref/yyaxis.html#bunqz2o-5

It works fine now. but bars are overlapping each other as it is shown in picture. I want to ask how can i make it that these two bars not overlap each other. Thanks

Yeah, for bar that's pit(proverbial)a(ppendage) that yyaxis isn't clever enough to recognize the overlap.

See ADDENDUM to Answer for the workaround...

Look at

doc yyaxis

to put the two on separate axes that will cover range of each variable independently for starters, at least....

ADDENDUM POST PLAINTIVE COMMENT ABOVE :)

If y is the data array, then

yyaxis left
bar([y(:,1) nan(size(y,1),1)],'grouped')
yyaxis right
bar([ nan(size(y,1),1) y(:,2)],'grouped')

This uses feature of most basic plotting routines in ML that NaN data are silently ignored; so you draw a 'grouped' bar plot on LH axes with the first column of data but NaN as placeholder for second and vice versa on RH axes.

Should be a higher-level way to tell yyaxis/bar together this is what you're trying to achieve without having to do it directly oneself, but "it is what it is" at present.
