Labelling of x axis

2 次查看(过去 30 天)
Hello Programmers,
I have an hourly data and I used a step size of 0.1 in my simulation.
I used 12 hours worth of data in my simulation.
I will like the x-axis of my graph to be in hours stead of the number of points.
please how can I do that?

There are 2 ways to solve this:
First is to plot in the actual hours instead of the points of the matrix that is holding the data, so, say your values are stored every second, instead of plotting
plot(x,y)
you should plot
plot(x/3600,y)
and that would adjust the values of the x-axis.
The second way is to manipulate the values that are displayed on the x-axis, these are called the ticks and tick labels, for example:
>> plot(1:20,sin(1:20))
>> h1=gca; %you are grabbing the handles of the axis
>> h1.XTick
ans =
Columns 1 through 7
0 2 4 6 8 10 12
Columns 8 through 11
14 16 18 20
>> h1.XTickLabel
ans =
11×1 cell array
{'0' }
{'2' }
{'4' }
{'6' }
{'8' }
{'10'}
{'12'}
{'14'}
{'16'}
{'18'}
{'20'}
>>
So you can change the values of XTickLabel. I would suggest to try the first method and see if that works.
Hope this solves your problem.
