MATLAB: surf Plot after rotating my data 
For anyone interested, I have found the solution.
If you ever want to rotate a 3D matrix where the x,y,z data is located in
the 3rd dimension, use the following for maximum speed and efficiency.
[m,n,z]=size(inMatrix);
outMatrix=reshape((A*(reshape(double(inMatrix),[m*n 3]))')',[m n 3]);
Where inMatrix is your initial 3d matrix, outMatrix is your output 3d
matrix, and A is your rotation matrix. Can be extremely useful when wanting
to code rotations in images, since images will have 2 dimensions along
their width and height, and the 3rd dimension will be the x, y and z
coordinates. This will allow you to easily plot an initial data set, rotate
it, then replot it.

Smooth surf plot of spectrogram in Matlab 
If you increase your overlap, it will be smoother:
[~,~,T,P]=spectrogram(W(:,end),200,199,256,fs);
But will also take longer to calculate. That's the tradeoff.

How to plot two lines in one graph in MATLAB? 
It's confusing that you've called these X and Y. Assuming that they are
actually two lines with linearlyincreasing xcoordinates, you have some
options. The simple way is to use hold:
plot(X);
hold on;
plot(Y);
hold off;
The other way is to combine them into a matrix. Provided they are the same
length (and assuming column vectors):
plot( [X Y] );
But more fundamentally, you have shown your data as a cell array instead of
a vector. You should convert these to vectors first. You can use cell2mat
for this:
Xv = cell2mat(X)';
Yv = cell2mat(Y)';
plot( [Xv Yv] );

matlab plot graph (only show >threshold) 
The plot function takes two arguments, the x values and the y values. If
you want to plot from 0 to 1000, set the x value:
x = ((e1)*1000):(e*1000);
plot(x, rows(e,:));
...
In order to plot the 'o' at the correct x value, include the x argument:
plot(peak_x(beat_count), rows(e,peak_x(beat_count)),'ro');
...
If you want to print data to a file every time the user finishes a segment,
open the file for appending right after the above line:
fid = fopen('OUTPUTFILE.txt', 'at');
fprintf(fid, 'x = %d; peak = %f
', peak_x(beat_count), peaks(beat_count));
fclose(fid);

how to plot an edgelist as a network graph in matlab 
Do you have the bioinformatics toolbox?
In that case:
Create a sparse adjacency matrix from the edgelist:
Adj_mat = sparse(from_list, to_list,1,nb,nb);
Thereafter, create a biograph object:
bg = biograph(Adj_mat, "some properties");
h = view(bg);
This will create a directed graph. If you want an undirected graph:
Adj_Tri = tril(Adj_mat + Adj_mat');
bg = biograph(Adj_Tri,[],'ShowArrows','off','ShowWeights','off');
h = view(bg);

Reading CSV File and using Surf to plot time seriesdata 
You will find an answer on the matlab help page here. I reproduce its
relevant example below. You will have to repeat these steps for each time
point.
One the many solutions to achieve a surface plot with X,Y,Z vectors is :
Generate unevenly sampled data within the range [8, 8] and use it to
evaluate the function:
x = rand(100,1)*16  8;
y = rand(100,1)*16  8;
r = sqrt(x.^2 + y.^2) + eps;
z = sin(r)./r;
The linspace function provides a convenient way to create uniformly spaced
data with the desired number of elements. The following statements produce
vectors over the range of the random data with the same resolution as that
generated by the 8:.5:8 statement in the previous sinc example:
xlin = linspace(min(x),max(x),33);
ylin = linspace(min(y),max(y),33);
Now use these points

Matlab plot graph(segment by segment) and user input threshold value before writing to txt 
You need to put the input statement outside the loop, or it will be
evaluated multiple times (every time all the other conditions are true).
But really, there are far more efficient ways to do what you want  based
on the fact that matlab likes statements to be vectorized (operate over the
entire array at once). Here are a few ideas:
rows = reshape( data, 1000, []); % the [] means "figure out what this
dimension has to be so it works"
d1 = diff( rows, 1 ); % take "first derivative" along first nonsingleton
dimension
pkLocs = find(d1(1:end1,:)>0 & d1(2:end,:) < 0 ); % peak = where
derivative changes sign
threshold = input('Key in the threshold value:');
[pk_i pk_j] = ind2sub( size(d1), pkLocs );
pkVals = rows( sub2ind( size(rows), pk_i, pk_j) );
aboveThr = find( pkVals > th

Different SURF Features Extracted Between MATLAB and OpenCV? 
Under the hood, MATLAB uses OpenCV for some of its computer vision
functions, including detecting SURF features. If you look inside the
$matlabroot/bin/$arch folder, you'll find OpenCV shared libraries in
addition to a gateway library ocv.dll).
In fact, the same reference paper is mentioned in the documentation of
both, which suggests that the algorithm parameters have the same meaning in
both frameworks.

How to plot grouped bar graph in core plot? 
Use the barOffset property to shift the plots off the given bar location
slightly. For example, with three plots, you might give the first plot an
offset of 0.2, the second an offset of zero (the default), and the third
an offset of +0.2, assuming your bars are one location unit apart.

Matlab: Saving plot images, override plot.m 
you can simply use the print command and save them into a directory that
you can also make using the mkdir command.
Sample code
clc; close all; clear all;
x = 1:10;
y = x.^2;
plot(x,y)
if exist('plots','dir') ~= 7
mkdir('plots'); % make directory if it does not exist
end
print dpdf ./plots/jawn.pdf
Read the print documentation, to learn how to print in other file formats
Also, I would not suggest overriding the plot command, and you will likely
not be able to find the source code for plot.m because that is proprietary
MATLAB code

Legend does not match plot lines on MATLAB plot 
The display of the red line as a full line is curious. In any case it's
related to your plotting a vector against a scalar.
This will plot equal length vectors and generate the behavior you expect:
plot(y, g, 'k', y, P1*ones(1,length(y)), ':r', y, P3, 'b');

Matlab; Scatter plot shift the plot 
Use the axis command:
>> axis([0 1 0 1]);
to set the limits of the axis (the range displayed).
See axis doc for more info.

Matlab density plot, Heat map, Matlab 
You can control the colour of each point like so:
scatter(x1, y1, [], C)
where C is the same size as your x1 and y1 matrices. Now if you describe
the rules of how you want this heatmap colour modulation to happen, we can
help you construct C from x1 and y1...

Matlab get an average plot out of several plot 
Assuming you don't have access to the original data you used for doing the
plots:
plot_data = get(get(gca,'Children'),'YData'); % cell array of all "y" data
of plots
average = mean(cell2mat(plot_data));
In order for this to work, you have to use this code right after doing the
plots, that is, without plotting to any other figure (gca is a handle to
the current axes).

plot a line graph in vb.net 
Entity Framework would be a good way to do it. EF returns a class object
that represents a table. Then you make a query and can apply filters and
get an IEnumerable(Of {record}) then you can iterate this List and supply
the parameters from the record. A function would be a better fit for
parsing a field and returning a value based on the given string. EF
simplifies getting your data and placing it in a class/property format so
you can use it in code. Documentation Tutorial
Example:
For Each rec As Record In dbModel.Records.Where(Function(o) o.clientId =
clientId).ToList
Chart1.Series("Student").Points.AddXY(rec.Name, GetYValue(rec.Amount))
Next
Private Function GetYValue(value As string) As Integer
Dim result As Integer = 0
Select Case value
Case "r"
result = 0

data to be given to plot on graph 
You are probably looking for what type to use to store in database, if it
is So:
LONGTEXT is probably excessive  it allows data sizes up to 4GB.
MEDIUMTEXT allows 16MB.
TEXT allows 64KB.
TINYTEXT allows only 255 characters.
Very few HTML documents are going to be 64KB in size, so a TEXT ought to be
suitable for you. If you really want to be safe, go for a MEDIUMTEXT.

Plotting graph in GNU PLOT using C# 
The problem seems to be that gnuplot cannot find the requested file. The
working directory of the process is not set to the gnuplot directory, but
probably to the directory of the application that is calling gnuplot.
EDIT Try to add either of the following lines to your code somewhere before
the extPro.Start() command:
extPro.StartInfo.WorkingDirectory = @"E:gnuplotin";
or
Environment.CurrentDirectory = @"E:gnuplotin";
If this is not working, it might be because your application does not have
read access to that directory. Try placing your insert.dat file in a
directory that with certainty can be accessed by any client application.
BTW, I also do not recognize the Standardization property that you are
using? That line should rather read:
extPro.StartInfo.RedirectStandardInput =

Is it better to plot android Graph using JAR or OpenGL 
Address your platform you want to use
This speed issue can weigh in on both ends.
The library (jar as you call it) approach will be faster to draw initially
because I assume they draw on canvas. We use this approach to draw some
complex charts on our app. This way is simple and straight forward. The
charts are mostly static with some features for interaction.
The OpenGL approach will take longer to render initially because it needs
to first load the GLView and start up OpenGL before the chart can draw and
this can sometimes be time consuming but as soon as this is loaded it will
be way faster to perform draw operations and fancy features than the jar
approach.
In the end it comes down to what you want to do. If you only want to plot a
chart and update it with the latest data I wouldn't

R: plot multiple lines in one graph 
You should bring your data into long (i.e. molten) format to use it with
ggplot2:
library("reshape2")
mdf < melt(mdf, id.vars="Company", value.name="value",
variable.name="Year")
And then you have to use aes( ... , group = Company ) to group them:
ggplot(data=mdf, aes(x=Year, y=value, group = Company, colour = Company)) +
geom_line() +
geom_point( size=4, shape=21, fill="white")

Core Plot bar graph  Bar does not show up 
The datasource should check the plot field using the predefined constants
(CPTBarPlotFieldBarLocation, CPTBarPlotFieldBarTip, and
CPTBarPlotFieldBarBase) rather than using "magic" numbers.
Most bar plots will require at least a location and a tip value for each
bar. Be sure the datasource returns the correct value for each field.
The length of a plot range should be max  min, not max. In this case, it
doesn't matter since the min value is zero, but it will matter in other
cases.
There are many examples of bar plots in the Core Plot example apps. The
Plot Gallery app is a good place to start.

Click on the graph coreplot 
Look at the example apps included with Core Plot. The Plot Gallery has an
example of adding a label when the user clicks a plot. The Mac version of
CPTTestApp shows another technique of drawing a crosshairs over the
selected point on a scatter plot.
Each plot has its own delegate that will be notified of the click. The
delegate methods all have the sending plot as one of the parameters so you
can use the same delegate object to handle more than one plot.

Plot graph iteratively during every update 
If you don't care too much about which color is which cluster, or you feel
like constructing a color map (which is actually pretty easy), you can just
do this without the for loop (your first piece of code):
plt.scatter(y[:,0],y[:,1],c=z,cmap='Paired')
(or substitute 'Paired' for you color map).

How to plot a grouped bar graph in R with different data structures

Core Plot Bar Graph YAxis issues 
As I seem to be finding with most things xcode, it is all about where you
put your code. If I have CPTPlotRange:PlotRangeWithLocation:Length before I
do my set up it is really slow and buggy. If instead I add it to the end of
my code after setting the other values for the axises suddenly there is
only a very minor delay. I actually got this code originally from a
tutorial and modified it to fit what I needed but I guess the tutorial
didn't have the same delay because the length of the data was much lower.
So all I did to fix this problem was put the following code after my axis
set up instead of before;
CPTXYPlotSpace *plotSpace = (CPTXYPlotSpace *) graph.defaultPlotSpace;
plotSpace.yRange = [CPTPlotRange
plotRangeWithLocation:CPTDecimalFromFloat(0)

How to plot line graph using json in Highchart? 
Two things:
categories should be an array of strings, so:
remove extra array here: var mydata = [[]]; > var mydata = [];
remove extra array here: mydata[0].push([line2[i].time]); >
mydata.push(line2[i].time);
data should be an array of numbers, so remove extra arrays the same way as
for categories.

How to plot stack series line graph in R? 
Here is some code that will give you what you want.
#Example Data

time06H = abs(rnorm(n))
time24H = abs(rnorm(n))
allPAL.DE = data.frame(time02H,time06H,time24H)
plot(0,0,xlab="Time",ylab="Values",type="n",xlim=c(0,2),ylim=c(min(allPAL.DE,0),max(allPAL.DE)),axes="FALSE")
box()
axis(1,0:2,c("time02H","time06H","time24H"))
axis(2)
abline(h=0,col="grey",lty=2,lwd=2)
for(i in 1:nrow(allPAL.DE)){
lines(0:2,allPAL.DE[i,],col=i,lwd=2)
}
You could add different options, colors and text to make the plot look
nicer but its the basic idea that you were asking for.

How do I plot a bar graph in ggplot where my bins are yearmonths 
I think this works:
Edit: Per the comments below
mydates$months < month.abb[as.numeric(format(mydates[, 1], format =
"%m"))]
mydates$Months < paste(mydates$months, format(mydates[, 1], format =
"%y"))
mydates$Months < factor(mydates$Months, levels = paste(month.abb,
c(rep(12, 12), 13)))
ggplot(mydates, aes(Months)) + geom_bar()+ scale_x_discrete(drop=FALSE) +
theme(axis.text.x = element_text(angle=90, vjust=.3))
The labels could be adjusted by making the bars horizontal with
coord_flip() or using theme(axis.text.x = element_text(angle=90, vjust=.3))

iOS Draw n number of bar graph Dynamically using core plot 
Your question is still at a higher level but i will try to answer as per my
understanding:
where i set the identifier dynamically : You can have some constants
strings which you can use for setting identifiers. If you want to make it
completely dynamic take a counter and use it's value to set as identifier
like:
plot.identifier = [NSString stringWithFormat:@"%d",counter];
Create the plot inside a loop as per dynamic req. and just after creating
instance set the identifier as per counter.
how handle every bar draw calculation in side delegate : This is not so
clear what you want to know. This method is called according to count you
will pass in delegate method:
(NSUInteger)numberOfRecordsForPlot:(CPTPlot *)plotnumberOfRecords {
return someCount;
}
The delegate method "numberFor

Excessive lag when loading view controller containing Core Plot graph 
Is maxDailyCaloriesInDataset large? The default axis labeling policy puts
tick marks and labels one unit apart along the axis. If the yRange is
large, this creates a lot of overlapping labels, which can be very slow.
Depending on the requirements of your app, either increase the
majorIntervalLength so it doesn't make so many labels, or change the
labeling policy. CPTAxisLabelingPolicyAutomatic and
CPTAxisLabelingPolicyEqualDivisions would be good choices.

Highchart datetime graph xaxis unable to get data on plot when min and max is on 
Although you are specifying min and max, your data has no x values
specified, so it is assuming that the date time values are starting at 0.
There are several ways to render the chart you want.
Firstly, you could specify x values in your data points e.g.
{x:Date.UTC(2011, 0, 1),y:2165}
Another way is to not use a datetime axis type, and just specify the
categories you want in the xaxis:
categories:["Jan","Feb","Mar","Apr","May","Jun","Jul","Aug","Sep","Oct","Nov","Dec"]
The second option is probably a bit simpler http://jsfiddle.net/K6xxz/
