need to know more about data visualization , can someone help me … i need to know every thing from a-z
That’s a pretty tall order. What are you trying to accomplish? That may help me make some recommendations for you.
depends on your need and nature of data
need more details
When I began my journey, a wise man once advised me to google Anscombe’s Quartet. This will provide you with a solid foundation on the importance of data visualization prior to beginning any data analysis project.
I’m pretty sure that knowing it all is hopeless … for data visualization is important to know what data you have. For instance if you have time series data, probably scatter plot or bar plot would be something you don’t want to do (histogram of returns not counting in bar plot 🙂 and stack graph something you want.
No matter what multivariate data you have, you must almost always do some transformation before plotting … ie PCA to obtain other coordinate system, cumsum for stackgraph, …
If you’re using R for data manipulation (or not) here are some nice books from which you could get some idea how to visualize different datasets:
H. Wickham: ggplot2
D. Sarkar: Lattice – Multivariate data visualization with R
N. Yau: Visualize this
