D3.js Chord diagram - Have text appear/disappear when hovering over an arc

由 佐手、 提交于 2019-12-08 08:32:47
问题 I'm trying to add a small function to the Chord Diagram created by Mike Bostock. When I hover over a certain arc, say Group A, I want a piece of text that I've placed to the right of the chord diagram to update its text to explain some insights that are particular to Group A. When the user moves his/her mouse away from the arc/chord (so all the chords become visible again), I want the text to go back to what it said before (which in my case is a short explanation of how to understand a Chord

Sharing a Legend between two combined ggplots

由 二次信任 提交于 2019-12-08 04:36:16
问题 This question was migrated from Cross Validated because it can be answered on Stack Overflow. Migrated 5 years ago . I'm currently trying to present two time series using ggplot2, both with very different scales, using two ggplots. I've combined the two separate ggplots, one on top of the other, using grid.arrange . In order to aid visualization, I'd like to make each line a different colour, and have this legend below the combined plot. As this may be relevant, I'm currently working in the

Match two trellis pages between two different graphs

由 霸气de小男生 提交于 2019-12-08 04:30:29
I want to have on the same page a pie chart and a bar chart, with trellis pages. They both have 5 columns as trellis, so 5 different pages that you can visualize by scrolling down. However, I would like to display the same pages at the same time for both graphs. For instance, let's imagine I'm on the pie chart, I scroll down one page - and so my pie chart is on page2 - I want my bar chart to automatically go to page 2 as well I tried to use markings but although it links a bit the two graphs, it doesn't change the trellis pages automatically Does anyone know how to do this ? as @scsimon

由 為{幸葍}努か 提交于 2019-12-08 04:14:21
问题 I am trying to visualize a function of 3 parameters over a cube in R^3 to get an idea of the smoothness of the function. An example of this problem is shown in the sample code below %pylab from mpl_toolkits.mplot3d import Axes3D import itertools x = np.linspace(0,10,50) y = np.linspace(0,15,50) z = np.linspace(0,8,50) points = [] for element in itertools.product(x, y, z): points.append(element) def f(vals): return np.cos(vals[0]) + np.sin(vals[1]) + vals[2]**0.5 fxyz = map(f, points) xi, yi,

How to do aligned scrolling through two chart areas without using AlignToChartArea?

由 倖福魔咒の 提交于 2019-12-08 02:54:03
问题 I have two ChartArea objects in a Chart ( System.Windows.Forms.DataVisualization.Charting is what I'm using). One is a Point graph, and the other is a RangeBar graph. The horizontal axis on the RangeBar graph is actually the Y axis, so I cannot just use something like this: Chart1.ChartAreas["Chart Area 2"].AlignWithChartArea = "Default"; I've figured out how to zoom both charts and keep them aligned, but when I try to scroll both charts by clicking on the scrollbar on one of the horizontal
