Plotting Table values in Matlab

Hi guys,

I'm reading a csv table into matlab and then plotting some data values.

My data is Education vs Age.

X -axis is the education and Y-axis is the age. Or I can have it vice versa if it's better.

However, I want to fix Y-axis so that range/interval are readatable. Below is my code and screen shot of my table.

If you look at the y-axis the numbers are all bunched up. I want to see some correct spacing.

For the data that I'm displaying the Y-axis is within the range of 18 - 60.

Thank you for your prompt response and assistance.

x = T2{1:3,4}
y = T2{1:3,1}


plot(x,y, 'LineStyle','none','Marker', 'o', 'MarkerSize',3)

You can specify the location of YTicks. For example

ax = gca;
ax.YTick = decimate(ax.YTick, 5); % it will reduce the number of ticks by 5

or

ax = gca;
ax.YTick = ax.YLim(1):10:ax.YLim(2); % will give space of 10 between Ticks.

Hi Ameer,

Thank you for your answer. My other question is where do I insert this part of the code you gave me. This is how I tested your code. see below. But I still get the same result.

When simply run your part of the code I get an empty graph.

x = T2{1:3,4}                                                                
y = T2{1:3,1}                                                                 
ax = gca;
ax.YTick = ax.YLim(1):10:ax.YLim(2); 

plot(x,y, 'LineStyle','none','color','red','Marker', 'o', 'MarkerSize',5) 

[Ameer Hamza]

Please place these lines after you code. Like this

x = T2{1:3,4}
y = T2{1:3,1}
plot(x,y, 'LineStyle','none','Marker', 'o', 'MarkerSize',3)
ax = gca;
ax.YTick = ax.YLim(1):10:ax.YLim(2);

Or a more robust one like this

x = T2{1:3,4}
y = T2{1:3,1}
figure;
ax = axes();
plot(x,y, 'LineStyle','none','Marker', 'o', 'MarkerSize',3)
ax.YTick = ax.YLim(1):10:ax.YLim(2);

Thanks Ameer,

During troubleshooting I found that one of my columns was a categorical data instead of numeric.

I made the change and it worked fine. I tried your solution also and it worked fine.

Cheers!

Glad to be of help.
