This project aims to collects tools for drawing The Data.
Data is often organized in strings, which is not that Intuitively.
To show the data more friendly, we often need to draw the data in a graph.
Different data need different tools, this project aims to collect or develop
- Git Repository: https://github.com/tinyclub/tinydraw.git
Tools developed by TinyLab.org
- oscope A digital oscilloscope, dramatize the data flow real time
This is based on the oscilloscope and tuna: http://git.kernel.org/?p=utils/tuna/tuna.git;a=summary
- histogram.sh draws the “two row data” in SVG with histogram
See an example output, you can open it to get an interactive view.
Tools Collected From Internet
- gnuplot can convert the data to a static graph.
Gnuplot is a portable command-line driven graphing utility for Linux, OS/2,
MS Windows, OSX, VMS, and many other platforms. The source code is
copyrighted but freely distributed (i.e., you don’t have to pay for it). It
was originally created to allow scientists and students to visualize
mathematical functions and data interactively, but has grown to support many
non-interactive uses such as web scripting. It is also used as a plotting
engine by third-party applications like Octave. Gnuplot has been supported
and under active development since 1986.
The Systrace tool helps analyze the performance of your application by
capturing and displaying execution times of your applications processes and
other Android system processes. The tool combines data from the Android
kernel such as the CPU scheduler, disk activity, and application threads to
generate an HTML report that shows an overall picture of an Android device’s
system processes for a given period of time.
- FlameGraph is able to draw a large number of the function call trees and the profiling data in a single SVG.
Flame graphs are a visualization of profiled software, allowing the most
frequent code-paths to be identified quickly and accurately. They can be
generated using my Perl programs on
https://github.com/brendangregg/FlameGraph, which create interactive SVGs.
- Gprof2Dot converts the output from many profilers into a dot graph.
It supports many profilers: prof, gprof, VTune Amplifier XE, linux perf,
oprofile, Valgrind’s callgrind tool, sysprof, xperf, Very Sleepy, AQtime,
python profilers, Java’s HPROF; prunes nodes and edges below a certain
threshold; uses an heuristic to propagate time inside mutually recursive
functions; uses color efficiently to draw attention to hot-spots; works on
any platform where Python and graphviz is available, i.e, virtually anywhere.
- VnstatSVG converts the vnStat output (network traffic data) to AJAX output.
vnStatSVG is a lightweight AJAX based web front-end for network traffic
monitoring; To use it, its backend vnStat must be
installed at first; It only requires a CGI-supported http server but also
generates a graphic report with SVG output, vnStatSVG is friendly to generic
Linux hosts, servers, embedded Linux systems and even Linux clusters.
- AnalyzeSuspend a tool for system developers to visualize the activity between suspend and resume
The Suspend/Resume project provides a tool for system developers to visualize the activity between suspend and resume, allowing them to identify inefficiencies and bottlenecks. The use of Suspend/Resume is an excellent way to save power in Linux platforms, whether in Intel® based mobile devices or large-scale server farms. Optimizing the performance of suspend/resume has become extremely important because the more time spent entering and exiting low power modes, the less the system can be in use.
