Adding axes to histogram on scatterhist, and changing graph area

Hello,

I have been trying for quite a while to add an axis with a title and a scale on my scatterhist plot. I have not found any means of doing this yet. Lastly, I have managed to get rid of the x axis histogram, but am unable to get rid of the space that it fomerly occupied. To give an idea of what I am trying to achieve:

The x-axis graph has been deleted with this code:

figure(3)
load data.mat
h = scatterhist(t, distance_totals,'Marker','.','MarkerSize',10,'Color','k','NBins',[15,15])
xlim([0,60]);
ylim([0,150]);
    set(gca,'fontsize',12);
    xlabel('Time(s)');
    ylabel('Distance (m)');
    title('Time vs Distance for 100 Iterations')
    %annotation('textbox', [0.75, 0.75, 0.1, 0.1],'string', mean(t))
    delete(h(2))
    

Would appreciate any help.

Thanks

How about something like this?

figure(3)
h = scatterhist(rand(100,1), rand(100,1),'Marker','.','MarkerSize',10,'Color','k','NBins',[15,15]);
set(gca,'fontsize',12);
xlabel('Time(s)');
ylabel('Distance (m)');
title('Time vs Distance for 100 Iterations');
h(1).Position([2 4]) = [0.13 h(1).Position(4)+h(1).Position(2)-0.13];
h(3).Position([2 4]) = h(1).Position([2 4]);
ax = axes('Position', h(3).Position,...
    'Color', 'none',...
    'YColor', 'none',...
    'XAxisLocation', 'top',...
    'XLim', h(3).YLim);
xlabel(ax, 'xlabel');
delete(h(2))

Oh, that's brilliant! Thank you very much!

You're very welcome :)

Some small improvementes:

• If you don't need the bottom histogram: delete(h(2))
• use the axis handles stored in h instead of using gca. h(1) is scatter axes h(2) is bottom hist, h(3) is left hist.
• To assign the "Xlabel" label to the top of the histogram (which is actually the yaxis), there's no need to add another axes.

axis(h(3),'on')
ylabel(h(3),'Xlabel')
h(3).YAxisLocation = 'right'

Oh nice! I like that much better than creating a new set of axes.

figure(3)
h = scatterhist(rand(100,1), rand(100,1),'Marker','.','MarkerSize',10,'Color','k','NBins',[15,15]);
set(h(1),'fontsize',12);
xlabel(h(1),'Time(s)');
ylabel(h(1),'Distance (m)');
title(h(1),'Time vs Distance for 100 Iterations');
h(1).Position([2 4]) = [0.13 h(1).Position(4)+h(1).Position(2)-0.13];
h(3).Position([2 4]) = h(1).Position([2 4]);
axis(h(3),'on');
box(h(3),'off');
h(3).Color = 'none';
ylabel(h(3),'Xlabel')
h(3).YAxisLocation = 'right';
delete(h(2))

^^ Great example of using axis handles in the graphics functions.

Thanks a ton folks! Much appreciated. Stay safe

How do I do this without deleting h(2) and instead adding a y-axis to the h(2) too? I tried to change the position command but it doesn't work at all.

@Tamara Szecs

1. remove the two lines that change the positions of h(1) and h(3)
2. remove the deletion of h(2)
3. Look at how Tommy turned on the axes and box for h(3) and repeat that process for h(2)
