How to make zero-value bar in bar graph visible?

I'm plotting a bar graph with the test results. Some of the scores in the test are 0, which makes the bars almost invisible. How to extend the bars so that they are all clearly visible, even the ones with value 0?

Change the color of the bar graph, use the different face color and edge color

as following

y=[75 91 105 123.5 0 150 179 203 226 249 281.5];
bar(y,'r','FaceColor',[0 .5 .5],'EdgeColor',[0 .9 .9],'LineWidth',5)

You can do some sorts of ways, change values as per your requirements-

Also, you can change the baseline (-1 or - some value as per your requirements) of the bar chart so that 0 is also visible. Check here how to change the baseline, check here

Thank You! Can You also advise me on other case: in my bar graph I have data in arrays which have 7 rows and in arrays with 5 rows. I want to show them all on one graph, but for the arrays with 5 rows matlab draws the other 2 rows as zero values, so it looks like this:

How to delete those 0-value bars? Thanks in advance for the answer!

Before plot you can delete the 0 from the array

y=[75 91 105 123.5 0 150 179 203 226 249 281.5];
>> y1=y(y>0)

y1 =

     75.0000   91.0000  105.0000  123.5000  150.0000  179.0000  203.0000  226.0000  249.0000  281.5000

Hi, thanks for the answer. However, there are no zeros in the 3 smaller arrays. They are all 5x3 arrays with no 0-values.
