Plot Data with Multiple Scales and further adjusting axes limits

Hi everyone,

I am having issues plotting two sets of data (with different limits) in the same space, with further adjustments to the y-limits.

My question is very similar to https://uk.mathworks.com/matlabcentral/answers/1571693-plot-lines-with-different-x-axes-on-the-same-matlab-plot, but the method described previously also failed with me data.

My code:

figure

set(gcf,'Color','w') % set the background of figure to white

yyaxis left

x=plot(duration_stats.sd, 'LineWidth', 1, 'Color', 'k')

hold on

yyaxis right

y=plot(duration_stats.spear_r, 'LineWidth',1,'Color','r')

The output graph:

(attached to the question, wont let me upload or add attachments)

Question: how do I further adjust the y-axis, for example, the left yaxis I want to be [0 0.035] and the right yaxis [1 0.096]?

Thanks!

@Vyte Jan, for your direct question about setting the two ylim(limits) for each of the left and right, do each before switching yyaxis (or by switching back to the appropriate yyaxis again and setting the ylim):

figure
set(gcf,'Color','w') % set the background of figure to white
yyaxis left
x=plot(duration_stats.sd, 'LineWidth', 1, 'Color', 'k')

    ylim([0 0.035])

hold on
yyaxis right
y=plot(duration_stats.spear_r, 'LineWidth',1,'Color','r')

    set(gca,'YDir','reverse') % the following y limits seem to imply wanting y reversed
    ylim([1 0.096]])          % but these may still need to be [0.096 1]

@Jeffrey Clark thank you! I've tried that before and it didn't seem to work, probably because I'd run 'hold on' before ylim. All fixed now :)

(also it wont let me accept your comment as best answer but thank you!)
