MATLAB: Changing the axis of a plot in a way that the data series starts at x=0 at a point at one point on the y-axis and ends on the right end of the plot

Question

hi,

I have this code:

dates=datenum(VIXdate)
y=VIX
plot(dates,y)
%datevc divides the date in different columns, first colum is the year,
%second the month and thrid the day
d=datevec(dates)
%Takes just the year (first column)
d=d(:,1)
%takes every year just once
[a,idx]=unique(d(:,1),'first')
ylabel('VIX');
set(gca,'xtick',dates(idx),'xticklabel',a)
set(gca,'Box','off')

this works fine, but the problem I faces is that the time series (y=VIX) does not start at the left end of the plot but instead there is a space between the y-axis and the first point of the time series. I know that when there are normal values on the x-axis, I can change it, but I am not able to do it with dates, what do I need to do?

Answer 1

This is still not a working example, the variable VIXdate is obviously unknown to us...

So the dirty way again:

ytix = get(gca,'YTick');
set(gca,'YTick',ytix(2:end));
