Question about YDir, reverse

Hello all,

I was trying to draw the plot and reverse the Y direction of the plot with following code:

 P = plot(x, y)
 set(P, 'YDir', 'reverse');

However, the matlab command says that

 Error using
 matlab.graphics.chart.primitive.Line/set
 There is no YDir property on the Line class.

Then if I click matlab.graphics.chart.primitive.Line/set, it says

 There is no documentation for matlab.graphics.chart.primitive.Line/set

What should I do? Any help will be appreciated.

Thank you

You can read all of the chartline Properties , and there is no mention of reverse anywhere on the page.

Perhaps you were thinking of the axes Properties , which has the option 'reverse' for any of XDir, YDir, and ZDir. Exactly how you do this depends on your code, but you could try this for a start:

set(gca,'YDir','reverse')

It should be

    set(gca, 'Ydir', 'reverse')

The plot as mentioned above does not have a property Ydir. However, the axes which the plot belongs to has this property.
