I'm building a dashboard using Dash in Python . My requirement is to plot a Scatter plot with values and move those values manually up and down which will perform a call back based on the new value the dot is moved inside the scatter plot.
My question is there a way to move the dots inside the scatter plot ? I read through internet and I was not able to find any solution . However I can see hovering/clicking the dots that does a call back but was not moved. Can anyone help me with this question.
Thanks,
Prathap

I am using Scatter Plot from Python. I have a quiver plot that contains an arrow going out of every point(x,y). and I have a specific point that I am interested in let us call it (c,d). My question is how can I know the points that are pointing to that point(c,d)?
ax.quiver(x_pos, y_pos, x_direct, y_direct)
For this code, how can I know if this arrow is directing to that point (c,d)? or to something else
I need to draw additional graphics on top of plotly go.Box traces, therefore I need to know X and Y coordinates for boxplot rectangle vertices. So far the only solution I came up with is basically recalculating everything (quartiles; X positions based on boxgap, boxgroupgap, etc.), then manually setting the y-axis range to know where everything will end up on the plot. This seems very cumbersome.
Is there a way in python to get the coordinates of go.Box boxplot elements, especially the grouped boxplots with categorical x-axis? As far as I understand these coordinates are calculated in JS frontend -- maybe there is some trick to get them back with Dash using callbacks?
I am solving the Cahn hilliard equation, and it's already working. If i plot the figures at different iterations I obtain the correct result at the end. However, I need to show the change in concentration over the course of time in a video and not in multiple plots. I have tried using FuncAnimation but I can't figure out how to do it. I can't create a function that includes the frames. My concentration matrix is already updating after each iteration so how can I just tell the code to plot every update on the video?
I want to plot boxplots on top of the scattered points like this.
I know I have to bin the data into intervals first but I couldn't find the function that does all of this. Sample x and y data are saved here as .npy.
I would look into using matplotlib. Boxes can be drawn as such:
https://matplotlib.org/gallery/pyplots/boxplot_demo_pyplot.html?highlight=boxplot
and scatter plots can also be drawn as such: https://matplotlib.org/gallery/lines_bars_and_markers/scatter_demo2.html?highlight=scatter
There is a search functionality on their site, along with plenty of documentation on how to utilize their library.
As for your specific question, you can specify zorder when drawing many of the things in matplotlib, and you could use that to define your boxplots to be on top. I believe if no zorder is defined that it draws items in the order they are encountered in your program (so you could draw scatter plots and then box plots and they should appear correctly as in your diagram above!
I’ve been working on bokeh plots and I’m trying to plot a line graph taking values from a database. But the plot kind of traces back to the initial point and I don’t want that. I want a plot which starts at one point and stops at a certain point (and circle back). I’ve tried plotting it on other tools like SQLite browser and Excel and the plot seems ok which means I must be doing something wrong with the bokeh stuff and that the data points itself are not in error.
I’ve attached the images for reference and the line of code doing the line plot. Is there something I’ve missed?
>>> image = fig.line(“x”, “y”, color=color, source=something)
(Assume x and y are integer values and I’ve specified x and y ranges as DataRange1d(bounds=(0,None)))
Bokeh does not "auto-close" lines. You can see this is the case by looking at any number of examples in the docs and repository, but here is one in particular:
http://docs.bokeh.org/en/latest/docs/gallery/stocks.html
Bokeh's .line method will only "close up" if that is what is in the data (i.e., if the last point in the data is a repeat of the first point). I suggest you actually inspect the data values in source.data and I believe you will find this to be the case. Then the question is why is that the case and how to prevent it from doing that, but that is not really a Bokeh question.
