MATLAB: Stretching axis to observe data

data acquisitiondatabasegraphmathematicsMATLABplotplotting

hey, I have plotted a graph as seen in the doc of Wind speeds vs Hourly Time(Jan 2000 to March 2015). As you can see the periods nor the characteristics cannot be clearly seen. The dataset is quite large with 131400 points, but is there a way to stretch the data out to observe it a better?

Well, since your monitor probably has only roughly 2000 pixels/line even if you could draw your plot with every bit for the graph line (no axis, no nothing else) there would still be some ~131/2 --> 65 data points/pixel so it's physically impossible to have enough resolution to show it all at one time. You'll have to look at pieces of the time series at a time to visualize more closely..

doc zoom  % for starters
doc xlim

MATLAB: How to create axis with perfect square ticks

The answer from @Mara provides all the tools you need, but there are still some caveats. Note that the first option will not set the spacing and the second option will cause a mismatch between the values and the labels.

I think the best solution would be to do all of these things:

Set the yticks to 0:50
Set the yticklabels to (0:50).^2
Take the sqrt of your data before plotting it

An easy way to "fake" this after setting "Box" to "off", as Peng Li suggests, is to make xline and yline. But it wouldn't be dynamic - if you change the axis limits, you'd have to re-draw the "fake" box

ylim = get(gca,'YLim')
xlim = get(gca,'XLim')
xline(xlim(2),'-k')
yline(ylim(2),'-k')

But just to comment, while a valid ask, it seems a very uncommon need...I don't think any editor or reader or consumer of plots would even notice/pay attention to such a detail, and if they noticed, I feel like at least 50% of the time (being generous with random chance) they would perceive it as odd rather than expected...
