Looking for program to graph a network with 2 clusters.

Fri, 28 Aug 2020 09:46:16 +0000

I'm a PhD student using qualitative content analysis to look at a number of documents to identify a norm cluster. The structure of the norms I'm trying to look at is that "ideations" link to "behaviors". I've coded the documents so that I know I have a spreadsheet with the coded behaviors in rows and the ideations in columns. The number in a cell then shows the overlap between a behavior and an ideation.

I'm looking for a program that would allow me to graphically portray this so that the ideations appear as bubbles clustered together, size dependent upon the number of times they were coded, with all behaviors clustered together in the same way and lines (size dependent on the strength of the connection) connecting the two. A simple example of this can be found on page 28 of this (problem is constant in my question).

Thanks in advance for any answers.

ploting the xticks to be datatime

Sat, 20 Oct 2018 00:47:40 +0000

I have a dataframe like below

                    MT_001	    MT_002	    hour
2012-01-01 00:15:00	3.807107	22.759602	00:15:00
2012-01-01 00:30:00	5.076142	22.759602	00:30:00
2012-01-01 00:45:00	3.807107	22.759602	00:45:00
2012-01-01 01:00:00	3.807107	22.759602	01:00:00
2012-01-01 01:15:00	5.076142	22.048364	01:15:00

I can easily plot it using

data.plot()
plt.show()

However, this doesn't show the xlabel. What if i want to see the graph where the xlabel shows the ticks with 4 hours apart?

plotting categorical radio

Wed, 17 Oct 2018 02:25:36 +0000

Hello,

I am trying to gain insight of the data but having hard time plotting it.

Suppose I have a data frame like below

ID	Feature 1	Class
1	a	good
2	a	good
3	b	good
4	b	bad
5	a	bad
6	a	bad
7	b	bad

In the above dataframe I have one feature "a" and "b" each has a good and bad class value.

for e.g

feature "a" has 2 good and 2 bad classes

feature "b" has 1 good and 2 bad classes

How do i visualize this and plot it in python ?
How would I do it for more than one features in different subplots?

Sorry if this question seems like a very basic question to ask
