I want to compose a Predicted Interval Plots is it possible to draw the same using Tee Chart
I think is possible. I recommend you taking a look in the, Demo Examples of TeeChartFor.Net, concretely, see the example functions that you find in All Features\Functions.
Could you tell us if the TeeChartFor.Net Demo examples help you to find as you want?
I hope will helps.
Thanks,

I'm using a tutorial (https://www.tidytextmining.com/nasa.html?q=correlation%20ne#networks-of-keywords) to learn about tidy text mining. I am hoping someone might be able to help with two questions:
in this tutorial, the correlation used to make the graph is 0.15. Is this best practice? I can't find any literature to help choose a cut off.
In the graph attached from the tutorial, how are clusters centrality chosen? Are more important words closer to the centre?
Thanks very much
I am not aware of any literature on a correlation threshold to use for this kind of network analysis; this will (I believe) depend on your particular dataset and how language is used in your context. This is a heuristic decision. Given what a correlation coefficient measures, I would expect 0.15 to be on the low side of what you might use.
The graph is represented visually in a two-dimensional plot via the layout argument of ggraph. You can read more about that here but the very high-level takeaways are that there are a lot of options, they have a big impact on what your graph looks like, and often it's not clear what is the best choice.
"Fit" in Gnuplot uses which method (Algorithm) for fitting any curve? How does it calculate the error in fitting parameters?
A rough idea about the method or the algorithm would be enough.
I am using the fit command quite often. GNUPLOT is using the least squares with the the Marquardt-Levenberg-algorithm. All available information are on this link [fit]. What they said about the error can be found here [error].
These are quite robust methods and can not be easily implemented. However, if you want have a look at the code that does the job you can find it on GitHub [code], that's the advantage with opensource :-).
Hope that helps.
I have faced with a problem which I have no clue even to find a proper keyword to search. So I ask a question here to expect even some keyword or tag.
The background is very complex. But the result I wanna achieve can be described as a simple scene.
Suppose I have a cube made of glass. The cube is full of sponge. And there's a person in the sponge. Now the person does some movement or action. Then of course the sponge is deformed. This person is described as a geometry. I know the person's original pose, which means I know the original geometry. And I also know the deformed geometry. I prefer to describe the sponge as points or grids in the cube. I know that finite element method can do this accurately. But Is there any interpolation method to calculate how the sponge's points will be?
I donot expect any accurate deformation. I just expect that some falloff to show the pinch or stretch.
Any keyword are welcome. Thx so much.
'cause the structure of my scene is fixed, I choose simple KNN to implement this feature. As structure is fixed, I create a kdtree at the very beginning. Then deform other points based on KNN.
I want to plot a figure like this one:
but with only sketched data curves. The x and y axes should not be sketched.
Is this possible using Gnuplot?
I think you may find this link useful, since it's exactly what you are asking for :)
http://rfonseca.github.io/xkcd-gnuplot/
Essentially, it applies a function to jiggle the line and make it pseudo-hand-drawn:
jiggle(x) = x*(1+(2*rand(0)-0.5)*0.015)
plot jiggle(sin(x))
And this is the result:
You may also want to increase samples with set samples 1000 to have better results avoiding spikes in jiggled lines.
(As a curiosity, that page is inspired by a StackExchange answer, that contains a very advanced (and amazing, IMHO) approach to this problem, unfortunately only for Mathematica users.)
I have a frivolous question. Is there any way to use an image in lieu of points in gnuplot? For example, if I was plotting data about pasta consumption or something, I would have pictures of pasta (instead of usual gnuplot points).
Another option is to find a dingbats type of font with a suitable glyph. Then you can use "plot with labels" using that glyph as the label string. See for example the 5th plot in the demo
http://gnuplot.sourceforge.net/demo/stringvar.html
I haven't played around with this feature at all myself, however, there is:
http://gnuplot.sourceforge.net/demo/barchart_art.html
Which shows the use of png files on a bar chart (Note, that this feature was added in Gnuplot 4.5 -- I think). With a little creativity, it seems like you could use that feature to do what you're asking -- although it would require a whole bunch of plot commands so it might be useful to write a script to generate the gnuplot script (or use iteration depending on your dataset) -- Obviously your image files would have to be in a format that your version of gnuplot understands as well ...
A possible strategy may be the plot with rgbimage option in gnuplot.
See the second example over here: http://www.gnuplot.info/demo_4.2/image.html
If you relate the center option with your data points, this may be possible.
