How to change line style of a plotted graph?

Hello,

I would like to change the linestyle of a plotted graph for making color blind people to understand my graph. The graph is already plotted. I have no basic data (anymore), but only the saved figure. I tried the follwing:

hline = findobj(gcf, 'type', 'line')

set(hline(1),'LineStyle',':')

But that didnt seem to work.I added my graph.

Does anyone knows how to do this?

You forgot to add the graph; and the saved figure file would also be helpful.

Sorry, it is added now.

Your code works fine for me on your graph. Make sure that "gcf" is indeed the figure you think it is (i.e. do you have other figures open too?)

[Roel]

Mmm, i do not know what i am doing wrong. I have indeed only one figure open.I also cleared my workspace. Does other versions of matlab have influence maybe?

[Roel]

I do manage to change the legend of the figure. But the plotted lines in the figure remain the same.

I found my mistake, had to change 1 in hline(1) to 7,8 or 9. Thanks anyway.

If we test this example

   plot(1:44)
hline = findobj(gcf, 'type', 'line')
set(hline(1),'LineStyle','--')

It seems to work
