Why does Tiledlayout return error when using a figure with datetime as x-axis?

4 次查看(过去 30 天)
Hello,
I am trying to use tiledlayout to display several figures. The figures use numbers (double) on the y-axis and dates (datetime) on the x-axis. When I run my code, I recieve the following error (repeated four times).
"Warning: Error updating Line.
Conversion to double from datetime is not possible."
Matlab displays the figure I opened in a seperate window; however, the tiltedlayout figure displays an empty figure
The code I am running is posted below:
open([pwd '\ClusterData\SlopeFigs\m10d30rSlp.fig']);
gh1 = gca;
figure (88)
t = tiledlayout(2,2);
nexttile
copyobj(gh1.Children,gca)
I tried an example figure from MATLAB with number on both axes and it works fine. Therefore, I believe the issue is related to datetime values not being supported in tiledlayout. Can anyone confirm?
Thanks,
Allon

datetime x-axis is supported in tiledlayout. Here's an example:
x = datetime(2024,9,3):hours(1):datetime(2024,9,5);
y = rand(size(x));
figure
tiledlayout(2,2)
nexttile
plot(x,y)
gh1 = gca; % go ahead and store the axes handle
The problem is trying to copy objects from an axes whose XAxis is a DatetimeRuler to an axes whose XAxis is a NumericRuler (which the new axes's XAxis is by default). This is reproducing the problem:
figure
t = tiledlayout(2,2);
nexttile
copyobj(gh1.Children,gca)
Warning: Error updating Line.

Conversion to double from datetime is not possible.
A workaround is to plot something with datetime x-values in the new axes first (making that XAxis a DatetimeRuler), then copy the stuff, then delete what you plotted first. Example:
figure
t = tiledlayout(2,2);
nexttile
line_to_delete = plot(datetime(0,0,0),NaN);
copyobj(gh1.Children,gca)
delete(line_to_delete)
There may be a better solution, but this seems to work ok.

Voss,
Thank you this was exactly what I needed! Your second comment was very helpful in pointing me to the correct solution. Much appreciated.
