Hi everyone,
I'm trying to add contour lines at 13 degrees to my pcolor plot, but I get the following error:
Error using contour
Input arguments must be numeric or objects which can be converted to double.
Here's my code:
t1 = datetime(2021, 5, 1)
t2 = datetime(2021, 9, 30)
dateVector = t1:t2
combinedaverages = [dailyaverages; dailyaverages06; dailyaverages07; dailyaverages08; dailyaverages09];
figure
pcolor(dateVector, depth, combinedaverages')
set(gca, 'YDir','reverse')
shading flat
ylim([0 70])
colorbar
hold on
contour(dateVector,depth,combinedaverages',[13 13],'k');
Variables in the code are:
combine averages: 153x33 double
depth: 33x1 single
dateVector: 1x153 datetime

The data are the variables you mentioned in your question. If you save them to a mat file and attach them we can run the code in your question.

hello again
maybe this ?
figure
pcolor(dateVector, depth, combinedaverages')
set(gca, 'YDir','reverse')
shading flat
ylim([0 70])
colorbar
hold on
contour(1:numel(dateVector),depth,combinedaverages','k');
