MATLAB: How to plot point in GUI – beginner matlab

gui problem

i have 3 variable to plot point in axes. 1st variable is Latitude for X, 2nd variable is Longitude for Y and 3rd variable is Safe Point for Z when the value is 1 will display green point and value is 0 display red point.

this my coding to load data from uitable5 where column 1 is for X, column 2 is for Y and column 3 is for Z;

table=get(handles.uitable5,'Data'); X=table(:,1); Y=table(:,2); Z=table(:,3);

how i can plot points with my data?

Best Answer

pointsize = 20;
scatter(X, Y, pointsize, Z);
colormap([1 0 0; 0 1 0]);  %red, green

MATLAB: Using elements of table as variable

A_mat = cell2mat(A);
x = A_mat(:,1);
y = A_mat(:,2);
z = A_mat(:,3);
scatter3(x, y, z);

MATLAB: Value in x-axis and y-axis not display same as data

Actually those values are exactly the same as the data, except that the GUI arrangement obscures the exponential multiplier. Here is a scatter plot with some of those data points, showing the exponential multipliers (highlighted in red):

>> X = [10000;10020;10100];
>> Y = [10000;10010;10020];
>> scatter(X,Y)

Two Solutions

arrange the GUI so that the exponential multipliers are visible.
manually set the tick label strings, something like this:

>> fun = @(ax)arrayfun(@(n){sprintf('%.0f',n)},get(gca,sprintf('%sTick',ax)));
>> set(gca,'XTickLabel',fun('X'))
>> set(gca,'YTickLabel',fun('Y'))
