if ax is your axis:
ax.XLim = [lowerLimX upperLimX];
ax.YLim = [lowerLimY upperLimY];

From the values on the tick labels, it would appear you may be approaching the limits of precision -- what are the actual limits on y -- are those real values, not in the fractional M value?
You can try scaling Y by 1E9 or 1E12 and then maybe have some numbers that will be easier to deal with.

unless your y axes labels have no connection to the plot, then your y values are in the range 0.1-1e-13 to 0.1+1e-13 . What axes limits and tick values do you need?

how to plot this values 0.1-1e-13 to 0.1+1e-13 in y axis?

Ran in:
You are already plotting the full range of values on the y axes. But you can force it to show more digits.
y = randn(1,100)/1e15 + 0.1;
figure
plot(y)
figure
plot(y)
ytickformat('%.14f')
figure
plot(y)
ytickformat('%.15f')
