= Rev (levels (Uspopage$agegroup)))Operation Result:If you need to draw a percentage stacked chart, simply modify the underlying data based on the work above.The R language implementation code is as follows:# Convert data to percent format Uspopage_prop = ddply (Uspopage, "year", transform, Percent = Thousands/sum (Thousands) * 100) # base function Ggplot (USP Opage_prop, AES (x = year, y = Percent, fill =

method is simple to add the marginal carpet function on the basis of the original scatter plot function. The R language implementation code is as follows:# base function Ggplot (Faithful, AES (x = eruptions, y = waiting)) + # Scatter graph function geom_point () + # Marginal carpet function Geom_rug ()　　Operation Result:add a label to a scatter plotThis example uses the following test data set:The method of adding labels to scatter plots is als

This completes the same circular pop-up effect as the rubber band.In addition, the navigation bar out is also more abrupt, here also use animation, let it from left to right slowly stretched out:New Animate ({from: {x:x1, y:y1},to: {x:x2, Y:y2},delay:"point '" Bounceout ') function (value) {node.setcenterlocation (value.x, value.y);},}).

Angularjs for data visualizationPreviewWe use ANGULARJS to realize the data visualization of bar chart, line chart and so on. The effect is as shown.Everyone can go to codepen-online preview-Download Collection-effectAnalysisThe following elements are required to implement this case: Basic knowledge of Angularjs Ng-repeat SVG Draw Line Passio

be sortable (nationality is not sorted). However, he has a limitation, that is, the data points of up to 6, otherwise cannot be identified. Therefore, the application of the occasion is limited. For example, if you have three machines with five identical parts, you can plot the amount of wear on each machine on a radar chart.7. Funnel ChartScenario: Funnel chart is suitable for process analysis of many business processes.Advantage: In site analysis,

"Today" data, to facilitate timely attention to the latest data, while grasping the trend of data changes. Data visualization: Complex data, clear and present Data

Python development [module]: CSV file data visualization,CSV Module 1. CSV file format To store data in a text file, the simplest way is to write data into a file as a series of comma-separated values (CSV). Such a file becomes a CSV file, as shown below: AKDT,Max TemperatureF,Mean TemperatureF,Min TemperatureF,Max Dew

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 acquisit
