Has anyone tried creating Normal Distribution chart using FLOT?
If so, can you please put me in a right direction with some suggestions and links to tutorial?
Thanks.
FLOT is simply a plotting engine. If you want to create a Bell Curve, you need to feed a probability density function a series of x values and plot the resulting points.
For instance I used the functions from here to create this:
Here's the jsFiddle that shows my work.

Basically, I have been trying to create a jet colored scatter plot in MATLAB.
Ref: Clayson et al. 2013
I have no z-value. Colormap is also not working. How exactly to do it? Thanks
What you are looking for is called a density scatter plot. You don't need a third dimension in order to create it, so don't worry for your missing z. The coloring algorithm is based on the density of the points.
Such plotting function is not included in the default Matlab packages and toolboxes, but after a quick search I probably found exactly what you are looking for. Take a look at this File Exchange release. It contains a full working function for creating density scatters together with a few illustrated usage examples:
This tutorial explains how to create Box plot in Tableau
First part of tutorial shows how to create below graphic, where the data points are within the box plot
Second part of tutorial uses Tableau's Box Plot function to create below graphic. Note how some points are located well past the Box Plot.
How is this a normal box Plot? Or is the video wrong? Please clarify
Tableau creates their boxplots by default putting whiskers at 1.5 times the inter-quartile range (IQR). Basically, this method excludes what it considers to be outliers. To adjust see Step 10 in the link below

I am workin on a some sort of System test wherein i have a set of readings in the form of a .mat file.
It has a structure in the .mat file with one field as Measurement. It has several Arrays(e.g air mass flow, velocity, carbon content) which further have fields like time and value.
From these, I Need to plot the velocity and the air mass flow against time. For that i wrote the following command which gave me the corresponding plots:
plot(Measurement.(Measurement.air_mass_flow.time),Measurement.air_mass_flow.value)
plot(Measurement.(Measurement.velocity.time),Measurement.velocity.value)
Now i Need to create a script in matlab wherein i can get both the curves one under the other i.e. on the same page. Can anyone help in the Approach i should procede with ?
ok now i will further extend my question.
I have two fields as velocity and acceleration. I Need to plot it on the same curve with grids on for the comparison. But the y axis for both are different.
the velocity y-axis is: (0:20:120), which should be displayed on the left side and the acceleration y-axis is: (0:2:12) which should be displayed on the right side.
i wrote the following code for this:
plot(Measurement.(Measurement.VehV_v.time),Measurement.VehV_v.value)
grid on
set(gca,'xtick',[0:500:2000])
set(gca,'ytick',[0:20:120])
hold on
plot(Measurement.(Measurement.accel_w.time),Measurement.accel_w.value)
grid on
set(gca,'xtick',[0:500:2000])
set(gca,'ytick',[0:2:12])
Do i Need to write a function for that as i am directly reading the values from the structure.
plotyy() also doesnt seem to work
But the axis are not matching and the graph for acceleration is very small. Could anyone help me out with this ?
I also want to add a Picture of the Graphs here but unfortunately there is some error here. I hope the question is clear without the Picture.
Yes you can use the subplot command, e.g.:
figure
subplot(1,2,1)
plot(Measurement(Measurement.air_mass_flow.time),Measurement.air_mass_flow.value)
subplot(1,2,2)
plot(Measurement.(Measurement.velocity.time),Measurement.velocity.value)
You can use help subplot on Matlab for further details or have a look at this:

I'm a little bit stuck on how to plot a histogram in MatLab, and typing help hist in MatLab does not make me any wiser. So I would appreciate any help!
Basically my problem is very simple. I have a vector, V, with five values, where each value represent the volume of a certain layer of the Earth. I simply want to create a histogram of these data, where the x-axis in my histogram should say "Inner Core", "Outer Core", etc., while the y-axis will display the volume. I've tried using the hist-command in various ways, but I can't get this to work. For instance, if I just type hist(V), the volume-values actually show up on the x-axis, and not the y-axis.
If anyone can help me how to make this simple histogram I will be very grateful! According to the instructions on my homework, I have to use the hist-command.
What you actually what is a bar plot.
bar([4,20,10,3,8])
I have a set of (X, Y) coordinates which, when plotted produce a graph as in the pictures below. What I am trying to do, is to find the coordinates of the areas (corner points) circled in red.
I have been trying to find ways to accomplish this, as those actual turning points represents my area of interest. Please note that I do not have the actual equation for those coordinates.
I would find it grateful if someone could please advise me, or give me some directions on how to go about this, either by using Matlab, or even some other ideas using some C++ tools.
I manage to solve this using a combinaison of the Point Cloud Library and Matlab. The former helped me to separate the coordinates in line segments (RANSAC) and using the latter, I was able to get the Equation of each line segments (Curve Fitting), and simply compute the intersection point through some basic math calculation.
