Hello everyone and Happy New Year
I am trying to draw a slip distribution graph and want to show the parts with no slip White
I found a Function in File Exchange "colormap jet_white", it is almost what I need except that by using this function my axis disappear!
Is there any way to superpose axis on top ,or any other way to have my color map from White Zero

thank you it gaves me a plot with white color at Zero,almost the same as jet_white(I attached it ).But still my first problem remain, how can I display the axes, like a black line or what ever(like https://jp.mathworks.com/help/matlab/ref/contourf.html).Now I just have slipdis.png ticks label

Try axis on after the plot.

Hi Samenah,
The help on jet_white states
"Since the "jet" colormap matrix can vary in size depending on the plot that it will be applied to, this function should be executed after any plot commands."
I wonder if moving the jet_white execution code below all of your plot commands will solve your issue? Please let me know. Thanks.

Thank you Jim
I am not sure if i did understand your advice or not,but I moved the colormap command to the very end part of my script(sorry its not a very neat script )
I attached what I've got !!slipdis.png

@Stephen Cobeldick it gaves me the graph without the axis slipdis.png

"I couldn't know how to debug and find the problem line!"
You have to learn to use the debugging tools. They are indispensible in any programming language. Start here:
https://www.mathworks.com/help/matlab/debugging-code.html
You will also find plenty of (video) tutorials online.

I figuered out how to debug. I think the problem started from scatter command.I attached a pdf file with 4 screenshot of debuffing process with the related command under it.the forth figure has no axes.Is there anyway to fix the problem,please.
