Questions tagged [visualization]

Constructing meaningful and useful graphical representations of data. (If your question is only about how to get particular software to produce a specific effect, then it is likely not on topic here.)

Overview

Data visualization refers to techniques for presenting results in graphical form, such as histograms, scatterplots, or boxplots. Data visualization is a special challenge for data with high dimensionality.

If your question is only about how to get particular software to produce a specific effect, then it is likely not on topic here. Programming questions (for example, in Python, or in R with ggplot, etc.) for which you can supply a reproducible example are usually welcomed on StackOverflow.

How do I figure out if subsets can be plotted in a normal Euler diagram?

In some cases, it may be impossible to draw Euler diagrams with overlapping circles to represent all the overlapping subsets in the correct proportions. This type of data then requires using polygons or other figures to represent each set. When…

How do you plot overlapping durations?

My data contains a set of start times and duration for an action. I would like to plot this so that for a given time slice I can see how many actions are active. I'm currently thinking of this as a histogram with time on the x axis and number of…

Visualizing large number of points as a 3D density map

The result of my computational simulation is a (time-dependent) system of large number (~100k) of moving points in a confined space. Each point has its own Cartesian coordinates as well as a weight (w) in the form of $(x_i,y_i,z_i;w_i)$. I'm…

Visualizing 28 different variables with 28 different colors?

ColorBrewer seems to be very useful in selecting a color pallet to represent factors that have up to 12 possible values. I have 28. Is it a horrible idea to represent 28 variables with color? If so, could you suggest an alternative visual…

How to visualize categorical data over time?

I'm visualizing results from lab tests. Most of these results are numerical and therefore easily communicated using line graphs, where the x-axis is time and the y-axis is determined by the range of possible values, like [0, 100]. EDIT: To be clear,…

How to visualize time-intervals

I have a pandas table with a start and end time for each entry. They don't intersect, but range from seconds to days. I want to visualize them, ideally the x-Axis being the date on which they occus, and the y-axis the time. However, I haven't found…
