Changing step size of a graph

I'm currently making a function that creates a graph for a given set of x and y data and I need to scale my X axis so that the step values are by 5 instead of the 10 that it creates automatically. How would I go about doing that? My current code is below.

    file = load('SampleXYData.mat');
    xData = file.xData;
    yData = file.yData;
    
    myFig = gcf; 
    myAx = axes(myFig);

    myPlot = scatter(myAx, xData, yData);
    myPlot.Marker = 'x';
    
    
    myAx.Title.String = 'Scatter Plot';
    myAx.YAxis.Label.String = 'Y';
    myAx.XAxis.Label.String = 'X';
    myAx.Box = 'on';
    
    endAt = length(myAx.XAxis.TickLabels);
    
    
    for i = 1:endAt
        
        cVal = str2double(myAx.XAxis.TickLabels{i});
    
        if mod(cVal , 10) == 0
    
             myAx.XAxis.TickLabels{i} = ['\bf', myAx.XAxis.TickLabels{i}];
           
        end 
    end

I'm assuming you mean you want to change the tick mark spacing.

You should just be able to set the axes Xtick property.

myAx.XTick=mytickvector;

or you can use set():

set(myAx,'xtick',mytickvector);

Of course, I don't know exactly what you're doing with the ticklabels.

How would I write a vector that would increase by 5 until the end? I know how to set it at a given value, but I want to have it works for varying sets of data.

I tried this, but it gave me an error saying "the end operator must be used within an array index expression'

myAx.XTick = (1:5:end)

Assuming we want the same extreme values:

myAx.XTick=myAx.XTick(1):5:myAx.XTick(end);
