how can i plot a horozontal bar graph where the bars color change acording to a formula?
i have 5 different hights (70, 115, 164, 216, 270) each going from 0 to 130 that change intensity acording to different formula for each hight
i want to draw a horozontal bar graph with hights on y axes 0-130 on y axes and the bar changing colors accoring to the formulas

Now i am giving you code for only generating 1 peak which is random, you ve to generate the remaining by yourself
figure,
h=barh([0 1],[zeros(1,131);randi(3,1,131)],'stacked','BarWidth',0.4);
X = 0:130;
Y = 0.000000272010410*X.^3 - 0.000071941838974*X.^2 + 0.004930888800712*X + 1.902355241509030;
Z=Y-min(Y);
Z=Z/max(Z);
for i=1:131
h(i).FaceColor = [1-Z(i) 0 Z(i)];%m(i,:);
h(i).EdgeColor = [1-Z(i) 0 Z(i)];%m(i,:);
end
