I'm trying to visualize a dataset which I've filtered down to just longitude/latitude, country name, year and a count of deaths. I'm trying to plot that using geoviews as I wish to add lot more to my dataset and interactive map would be a great add on
My code is as follows: (for_plot is the dataframe)
# Plotting the graph
Best = gv.Dataset(for_plot)
points = Best.to(gv.Points, ['longitude', 'latitude'], ['deaths', 'country'])
(gts.Wikipedia * points).opts(
opts.Points(width=600, height=350, tools=['hover'],
size='deaths', cmap='viridis'))
This creates a perfect graph put the 'size' function doesn't work. If I change size to color, graph is not generated. I'm okay with either but just need atleast one marker.
Thanks for any help
Tried to switch values for color instead of size, works with year but not deaths
Here is a sample of my data:
Time,Value,Name,Type
0,6.9,A,start
40,6.9,A,start
60,6.9,A,start
0,0.01,B,start
40,0.01,B,start
60,0.01,B,start
0,1.0,C,start
40,1.0,C,start
60,1.0,C,start
0,0.08,D,start
40,0.08,D,start
60,0.08,D,start
0,0.000131,E,End
40,0.00032,E,End
60,0.99209,E,End
0,0.002754,F,End
40,0.00392,F,End
60,0.01857,F,End
0,0.003,G,End
40,0.00516,G,End
60,0.00746,G,End
0,0.00426,H,End
40,0.0043,H,End
60,0.0095,H,End
0,0,I,End
40,0.0017,I,End
60,0.0183,I,End
And my code below:
import plotly.express as px
import pandas as pd
df=pd.read_csv('tohistogram.csv')
fig_bar = px.histogram(df,x='Name',y='Value',animation_frame='Time',color='Name',facet_row='Type')
fig_bar.update_layout(yaxis_title="value")
fig_bar.update_xaxes(matches=None)
fig_bar.for_each_xaxis(lambda xaxis: xaxis.update(showticklabels=True))
fig_bar.show()
`
Fig1:
Fig2:
With the data point listed above, I wanted 2 histogram separated by type (start,end) in one frame with one animation_frame
Tried the above code, as one can see from the image I could partial achieve but from Fig1: second histogram has (A,B,C,D),excepted just E to I.
2. Figure 2 was when I played the run button and auto scaled then I see A-D are gone and only E-I,
This is what I wanted to achieve in the first place itself, before running 2 histogram should sort as per 'Type'
A. Is it possible I tried couple of things like removed color
fig_bar = px.histogram(df,x='Name',y='Value',animation_frame='Time',facet_row='Type')
histogram sorts as per 'Type' of course no color but no label in second x-axis.
B.fig_bar = px.histogram(df,x='Name',y='Value',color='Name',facet_row='Type')
It sorts but no animation
What I am trying is it possible?
need 2 histogram with in the same frame sorted by 'Type',color and animation_frame?
C. Only if possible then, how to label y-axis of the first histogram from sumofValues to user-defined axis name and also have its own axis range.
D.I didn't come across any example but on the histogram, on mouse hover can I show another simple line graph image instead of text or value?
Thank you
I am trying to plot random rows in a dataset, where the data consists of data collated across different dates. I have plotted it in such a way that the x-axis is labelled for the specific dates, and there is no interpolation between dates.
The issue I am having, is that the values plotted by matplotlib, do not match the entry values in the dataset. I am unsure as to what is happening here, would anyone be able to provide some insight, and possibly as to how I would fix it?
I have attached an image of the dataset and the plot, with the code contained below.
The code for generating the x-ticks, is as follows:
In: #creating a flat dates object such that dates are integer objects
flat_Dates_dates = flat_Dates[2:7]
flat_Dates_dates
Out: [20220620, 20220624, 20220627, 20220701, 20220708]
In: #creating datetime object(pandas, not datetime module) to only plot specific dates and remove interpolation of dates
date_obj_pd = pd.to_datetime(flat_Dates_dates, format=("%Y%m%d"))
Out: DatetimeIndex(['2022-06-20', '2022-06-24', '2022-06-27', '2022-07-01',
'2022-07-08'],
dtype='datetime64[ns]', freq=None)
As you can see from the dataset, the plotted trends should not take that form, the data values are wildly different from where they should be on the graph.
Edit: Apologies, I forgot to mention x = date_obj_pd - which is why I added the code, essentially just the array of datetime objects.
y is just the name of the pandas DataFrame (data table) I have included in the image.
You are plotting columns instead of rows. The blue line contains elements 1:7 from the first column, namely these:
If you transpose the dataframe you should get the desired result:
plt.plot(x, y[1:7].transpose(), 'o--')
I'm trying to plot a multi line-graph plot from a pandas dataframe using seaborn. Below is a .csv of the of the data and the desired plot. In excel I simply selected the whole dataset and swapped the axis. Technically there are 110 lines (rows) on this, but many aren't visible because they only contain 0's.
This is my code:
individual_burst_data = {'nb001':nb001, 'nb002':nb002, 'nb003':nb003, 'nb004':nb004, 'nb005':nb005, 'nb006':nb006, 'nb007':nb007, 'nb008':nb008, 'nb009':nb009, 'nb010':nb010, 'nb011':nb011, 'nb012':nb012, 'nb013':nb013, 'nb015':nb015, 'nb016':nb016 }
ibd_panda_conv = pd.DataFrame(individual_burst_data)
sns.lineplot(data = ibd_panda_conv, x = individual_burst_data, y =ibd_panda_conv)
Other sources seem to only extract one column, whereas I need all the columns.
I tried to create an index for the y-axis
index_data = list(range(0,len(individual_burst_data)))
but this didn't work either.
The seaborn lineplot() documentation says:
Passing the entire wide-form dataset to data plots a separate line for each column
Since you want a line for each row instead, you need to transpose your dataframe, so try this:
sns.lineplot(data=ibd_panda_conv.T, dashes=False)
The goal is to plot the data frame I'm working with on a single chart, with a line for each value of init_population where the y-axis is count and x-axis is tick_number.
I've figured out how to use groupby() and plot() together to make this:
As you can see, all the lines are there nicely, but I'm pretty confident that the blue at the top that doesn't follow the relationship the other lines are following is actually a different column of data.
So that this is reproducible, the data is available here.
import pandas as pd
max_runs_data = pd.read_csv('clean_table.csv')
del max_runs_data['visualization']
max_runs_data.columns = ['run_number','init_population', 'tick', 'turtle_count']
max_runs_data.set_index('tick', inplace = True)
test_plot_1 = max_runs_data.groupby('init_population')['turtle_count'].plot()
test_plot_2 = max_runs_data.groupby('init_population').plot(y='turtle_count')
test_plot_1 is the linked image, test_plot_2 is a separate plot for each group.
Is it obvious how to specify the columns for x and y without losing the grouping on a single chart?
Thanks
