How to plot contour of an xy plot with a constant value?
I have several data sets (I have selected two lines in this case. I want to plot them as contour lines with different z values. For example, I want to plot the xy-data with z values as 40 and 30. As the lines extend beyond my area of interest, the current are of interest is 0 to 120 in x and 0 to 220 in y axis. I tried using meshgrid which I have used for plotting contour plots but I cannot convert these known values of lines into contours.Your help will be much appreciated.
xy = readtable(‘xy_data.xlsx’);
x1 = xy.x40;
y1 = xy.y40;
x2 = xy.x30;
y2 = xy.y30;
figure
rectangle(‘Position’,[0 0 120 220]) % the contour line can be only drawn in this box
axis equal
hold on
plot(x1,y1)
