if statement for colour coding data

Hi,

I have latitude, longitude and depth data.

I am wanting to create a 2D plot of Lat Vs Long and plot the depth shown as a corrosponding colour indiacting its depth. I would like it to plot 2colours:

Green if depth <11.9 km

Red if depth < 19.8 km

I have created an if statement so far but it only shows the red stars

Thnak in advance! Pri

Create a mask:

greenDataIdx = Depth <= 11.9;
plot( Lat( greenDataIdx ), Long( greenDataIdx ), 'g*' )
hold on
...  

Then plot your other data similarly. In your example there is no data with depth > 11.9. I was going to ask what happens to data > 19.8, but there isn't any. You can do the red data just the same though anyway, if any exists:

redDataIdx = Depth > 11.9 && Depth <= 19.8

An if statement where the target of the if is a vector is very rarely what you want. It will evaluate to a single scalar for the entire array.

Hi Adam, it worked!

Thank you so much
