charts

问题 Here is my data structure: data = {'2013': {1:25,2:81,3:15}, '2014': {1:28, 2:65, 3:75}, '2015': {1:78,2:91,3:86 }} My x-axis is the number [1,2,3] My y-axis is the quantity of each number. For example: In 2013, 1 is x axis while its quantity is 25 . Print each individual graph for each year I would like to graph a bar chart, which uses matplotlib with legend on it. 回答1: import matplotlib.pyplot as plt import pandas as pd data = {'2013': {1:25,2:81,3:15}, '2014': {1:28, 2:65, 3:75}, '2015':

问题 I have 2 arrays: values = [1,2,3,4,5,4,7,2,9,10]; colors = ['red','red','blue','blue','green','green','orange','orange','pink','pink']; I am trying to build a D3 Bar chart where each bar has height of 10 times the value and corresponds to the color that has the same index as the value. This is what I have so far: d3.select("body").selectAll("div") .data(total_data) .enter() .append("div") .attr("class", "bar") .style("fill", function(d) { return colors[values.indexOf(d)]; }) However, say we

问题 I'm using Chart.js and I'm looking for help with custom images for each point on a scatter graph. I've tried using a javascript array of images but it isn't working. I'm new to canvas and html5. What I would like is for each point to be a small profile picture of the user instead of a circle. An example would be greatly appreciated. I currently have: var ctx = document.getElementById("member-graph-scatter"); var myChart = new Chart(ctx, { type: 'line', data: { datasets: [{ label: 'Miles /

问题 I'm working with VBA trying to make charts. The chart is created like it should, but when I try to define a title, I get this error: "run time error '-2147024809 (80070057): this object has no title." my VBA line is: ActiveChart.ChartTitle.Text = "From " & Cells(Start, Prev) & " To " & Cells(Start, Op) & " - Recomended Setup: 0" Does anyone has any idea why It's not working? (the same line worked on another chart already...) Thank you! 回答1: That is because you need to create the title before
