Custom grid on a plot
显示 更早的评论
Hey all,
I have a plot that represents an error of 7 models in the months. I wanted to split each month's results by a line or grid to determine it more clear. so I used this code:
set( gca, 'YGrid', 'on' );
But as you can see the bars not adjusted between the grids; for example, if you look at Jan results, some of them appear before Jan line and some of them appear after this line. How I can have a line that split each month's results?
Thank you so much.

Can you show the commands used to plot this graph? It would be better if you can also attach the variables used to make this bar plot.

If the x-axis is a datetime axis, compute the 15th of each month and use plot(), line(), or xline() to plot vertical lines on the 15th from min(ylim()) to max(ylim()).
If the x-axis is numeric and each month is represented by x = 1,2,...,12, then your x values will be +0.5.
If you get stuck, show us what you've got and I'd be glad to help straighten it out.
Demo
fig = figure();
ax = axes(fig);
xlim([0,13])
ylim([0,10])
hold on
plot((.5:1:12.5).*[1;1], [min(ylim(ax)),max(ylim(ax))], '-k', 'Color', [.5 .5 .5])
ax.XTick = 1:12;
Or use xline()
fig = figure();
ax = axes(fig);
xlim([0,13])
ylim([0,10])
ax.XTick = 1:12;
hold on
arrayfun(@(x)xline(x,'-','Color',[.5 .5 .5]), .5:1:12.5)
