LGPL licensed so it's commercial friendly. For really simple charts take a look at the jQuery sparklines plugin. It does some really wonderful things actually. 回答2: JPGraph is a very powerful charting library for PHP 回答3: Not really PHP, but I find amchart really easy to implement and they

问题 I have a page that displays data in a form of a Pie Chart. I use Google Charts and here is the code: <script type="text/javascript" src="https://www.google.com/jsapi"></script> <script type="text/javascript"> google.load("visualization", "1", {packages:["corechart"]}); google.setOnLoadCallback(drawChart); function drawChart() { var data = google.visualization.arrayToDataTable([ ['Product', 'Sale In Percent'], ['product2', 5.5], ['product3', 7.5], ['product4', 1.5], ['product5', 8.5], ]); var

问题 I plot a piechart using pyplot. import pylab import pandas as pd test = pd.Series(['male', 'male', 'male', 'male', 'female'], name="Sex") test = test.astype("category") groups = test.groupby([test]).agg(len) groups.plot(kind='pie', shadow=True) pylab.show() The result: However, I'm unable to remove the label on the left (marked red in the picture). I already tried plt.axes().set_xlabel('') and plt.axes().set_ylabel('') but that did not work. 回答1: You could just set the ylabel by calling pylab

问题 I'm trying to incorporate Baidu's echarts (which look really good). However, there is a lot of whitespace around the actual graph when one doesn't set a title nor uses their toolbar. Is there a way to have the graph/chart use more of the canvas? My current solution to add an extra inside the container one and then set it's width and height to be be bigger by the margins I want to remove and the offset it by setting 'top' and 'left' to negative values of the respective margins. Not elegant and

问题 I'm trying to make a donut chart that looks like one below I'll be using angularJS, SVG and D3.js I've no clue how to get those rounded ends, Please help. Thanks. 回答1: Simple answer: you use masks. We use a mask to draw the inner portion of the bezel. And a mask to cut the hole in the middle. The hole mask isn't really necessary. You could form the donut with thick lines. But it seemed easier to me to draw circular sectors, then make the hole. Here it is in SVG form. I'll leave the conversion

问题 I'm using GraphView library (see: https://github.com/jjoe64/GraphView or http://www.jjoe64.com/p/graphview-library.html) But I would like to use Date/Time for the X-as. Does anyone knows a easy way to accomplish this or can anyone push me in the right direction? 回答1: GraphView is a great library to use, i find it the easiest as well. The first step in doing this would be to add a String Variable in the GraphViewData Class within GraphView.java. Like So: static public class GraphViewData {
