dataviz | Data visualization guide for presentations, reports, and dashboards | Data Visualization library

I'm leaning python pandas and playing with some example data. I have a CSV file of a dataset with net worth by percentile of US population by quarter of year. I've successfully subseted the data by percentile to create three scatter plots of net worth by year, one plot for each of three population sections. However, I'm trying to combine those three plots to one data frame so I can combine the lines on a single plot figure.

Data here: https://www.federalreserve.gov/releases/z1/dataviz/download/dfa-income-levels.csv

Code thus far:

I want to change category axis label text styles, how could I do it in amcharts4? Below is the code,

Sir I Used String Concatenation process what I think if there is filename as “plugin1” then in that file “plugin1.dll” will be there so I concatenate the string in the such way that output will be “C://DataViz//plugin1//plugin1.dll” then using simple fopen function i check whether there is file in that given path or not if not then “return NULL” or return “path”.

I'm here because I'm in struggle with some sliders for my dataviz app.

I already did a chart with a slider and it work fine, but now I want to do the same with ColumnChart instead of LineChart... :

Here is the working code :

From a set of two variables:

I had an idea for a visualization, that includes generating a plot for each row in my dataset (58 rows), showing the relative position of the value that i select, in a scale (e.g.: 58 cities and the position of the population size of one city relative to others).

Here's a code sample showing my data structure (nregs the name of regions I'm studying). I want to create a 'rank plot' as I've showed for each row, one plot ranking based in total_pop and other based in urban_pop.

I'm struggling with this nested document too much. I tried to read the document and also follow other SO responses to see if it works for me, but I'm not getting the results that I'm looking for. I want to extract some information from a big nested document.

DATA

I've uploaded the data to mongo playground. https://mongoplayground.net/p/7nbLtXMlFMx

I am trying to do a basic D3 interaction with a bar graph. The only thing that I want to do is hover the mouse on a bar and it will return the datum that is associated with that rectangle. But whenever I hover over the bar I get the MouseEvent constructor instead of the datapoint from the datum, I get the MouseEvent.

I don't know if my d3 selections are off.

I'm trying to load some json data into my React app and make some modification to the data before using it (adding one more column with additional data to each row of dataset) in order to create a D3.js visualization. I managed to get it working and displaying in console.log, but, however, whenever I'm starting to make any changes to my app the following window with an error pops up:

I'm not sure why exactly this is happening. I tried to apply this modification helper function by adding one more 'await' to fetchUrl() function (something like await addQuarterStringsToArr(data)) or doing it with fetch API in the main component, but in all those cases I didn't get a desired dataset with an additional column.

Here is my codesandbox

Could you please let me know what am I doing wrong here? I'm quite new to React and programming in general, therefore I'm confused on how to resolve this issue.

Thank you in advance!
