best visualization software

First set up the basic environment, assuming there is already a Python operating environment. Then need to install some common basic library, such as NumPy, scipy for numerical calculation, pandas for data analysis, Matplotlib/bokeh/seaborn for data visualization. And then on demand to load the library of data acquisition, such as Tushare (http://pythonhosted.org/tushare/), Quandl (https://www.quandl.com/) and so on. There are also a number of free da

Dashboards, big data, data visualization, data analysis-more and more people and businesses are starting to use their data to do something interesting. In my career, I have been privileged to participate in a large number of data-oriented interface design, and I would like to share some ideas about how to create this particular and meaningful product. A lot of people have discussed this topic and I will focus on the most influential part of the creat

This example is a flash AS3.0 example tutorial, in the tutorial we will learn to use the Soundmixer.computespectrum () method to build a simple sound visualization program (that is, wave diagram), hoping to bring help to friends ~ ~ AS3.0 constructs a simple sound visualization program (wave pattern): Use the Soundmixer.computespectrum () method to display the Sound Wave chart: import Flash.display.Grap

Although the ability to provide a custom look for a control is useful, developers should be able to use one control without having to provide custom visualization. This control should work exactly as it is used in its most direct way. This means that the control should provide a default set of values. These default visualizations are stored in the component's binary resources, and the source file used is theme "Generic.xaml." If you created a project

Tensorboard is an official visualization tool provided by TensorFlow. The data in the model training can be summarized and displayed. This article is based on the tensorflow1.2 version. This version of the Tensorboard interface is shown in figure:Image.png The Tensorboard supports 8 visualizations, which are the 8 tabs in the figure above, namely: scalars: Scalar curve.

Tensorboard:tensorflow comes with a visual tool. The chart visualization with Tensorboard encountered a problem that the chart does not display.Environment: Ubuntu systemRun the code to get the TensorFlow event file logs, for example the path is:/home/wang/tensorflow/logs, logs also contains train and test. At this point, Tensorboard runs by reading the event file by typing the command in cmd: tensorboard--logdir=log file path. According to our curren
