I have a list of 3-dimensional points. I want to plot them in a plane scatter plot (using the first two-dimensions), and then color each point according to the third value. How can I do this?

How can I set xlim and ylim with VegaLite? Without defining those, the plot is totally off.

Scale Vega-Lite - a high-level grammar for statistical graphics. Vega-Lite provides a higher-level grammar for visual analysis, comparable to ggplot or Tableau, that generates complete Vega specifications. Vega-Lite specifications consist of simple...

Came across with this question. Just an update using Plots scatter([1,2,3],[4,5,6],color=["red","blue","black"],legend=nothing)

Congrats on the beautiful wrapper to the PGFPlots that you have been developing. For high-quality plotting in the Julia environment, it seems second to none. I have a similar problem to that posted by @e3c6 , but I want the third dimension to be passed into SIZE rather than into COLOR in the plane s…

Actually, on page 407, section 4.25 of the documentation of PGFPlots (Version 1.17 – 2020/02/29), there is detailed information about the introduction of the size of a third variable into a 2D scatter plot. It comes with the title: /pgfplots/visualization depends on=〈expression〉\as〈\macro〉 …

In plots.jl there is the option of using marker_z. using Plots x= rand(10) y= rand(10) z= rand(10) scatter(x,y,marker_z=z)

Thank’s, but this is not what I need. I can do this both in Plots or in PGFPlotsX. Your suggestion solves the problem initially posted by @e3c6 : a 2D scatter plot (x,y), and the third variable/array passing information by coloring the points according to its values. So you are adding one further dim…

This problem I am raising must be easy to solve, and in some fields, this output I’m looking for is frequently used. For example, with Plotly (Python), the pice of code that does a similar job is as simple as this: import plotly.graph_objects as go import numpy as np np.random.seed(1) N = 100 x = …

You can also pass the size of the markers via the markersize argument. Other options like markershape, markerstrokewidth, … are listed here: Series Attributes · Plots

Thank’s a lot for your help. In Plots, it is as easy as this: using Plots x= randn(200) y= randn(200) z= randn(200) scatter(x,y, marker_z = z, markersize = 5*z, color = :jet)
