Chart not rendering with Shiny R and NVD3

由 不打扰是莪最后的温柔 提交于 2019-12-01 11:35:15
问题 I have been attempting to create a Shiny timeseries plot using NVD3 library. Am relatively new to R, Shiny and NVD3. The problem is that when I run the ShinyApp, no chart renders on the browser. Using chromes developer tools, I can see that the div for myChart is created and populated with data, but not understanding why I cannot see the chart itself. Would appreciate any and all help on this matter... My code is like so: #ui.R require(rCharts) shinyUI(pageWithSidebar( headerPanel("Population

How to remove NVD3 chart resize/update delay

由 六眼飞鱼酱① 提交于 2019-12-01 10:33:55
I've created an NVD3 multiBarChart and placed it in a jQuery resizable container. When resizing the chart, each render incurs the same delay as when the chart is first drawn: staggered left-to-right delayed drawing of the bars. This looks cool when the chart is first drawn, but it's a nuisance when resizing the chart. I've experimented with nv.d3.css, reducing every delay to 0ms to no avail. Haven't yet inspected the NVD3 JS and am hoping not to need to. Fiddle: http://jsfiddle.net/a5Fnj/10/ var container = $("#mycontainer"); $(container[0]).resizable(); var svg = d3.select(container[0])

unable to change legend symbol nvd3 bubble chart

由 回眸只為那壹抹淺笑 提交于 2019-12-01 10:23:40
问题 In my nvd3 bubble chart, each group of points has a different symbol but the legend has all as circles. The code is here. I have only come across this .showLegend(false) which enables to hide or show the legend. I am unable to understand how to change the symbols in the legend. 回答1: nvd3 does not give you direct access to the internals of the legend. However, you can alter it fairly easily using d3 selections to manipulate its various parts. Start by creating a selection of all elements with

I'm new on nvd3 after testing the D3js the last week. I'd like to load data from .csv file with nvd3 , that I did on D3 but I'm not able to do it with nvd3... Someone knows how to do it? With D3 I write the next lines and I get the data from my wather.csv: d3.csv("weather.csv", function(error, data) { data.forEach(function(d) { d.date = parseDate(d.Hour); d.T = +d.T; }) }); Considering my weather.csv file like: "Hour";"T"; "25.04.2013 12:00";"18.7"; "25.04.2013 11:00";"18.5"; "25.04.2013 10:00";"18.4"; "25.04.2013 09:00";"18.9"; ...

How to force nvd3 to display the equal number of ticks as that of the values plotted on the graph-nvd3

由 ∥☆過路亽．° 提交于 2019-12-01 08:30:39
How can force nvd3 graph to have certain number of ticks to be displayed, for example, please find below the image of the graph plotted: as seen below I have 7 values pushed to the array holding the 7 days of the week. However looks like they have more number of ticks than the actual values. What I'm looking for is something similar to this: http://nvd3.org/examples/line.html However when i hover over these ticks they are misaligned as shown: thats where the graph line should be and thats where the hovered tick shows the tooltip.but for some reason i dont get 7 ticks displayed instead gets 10

NVD3.js Get Data Point's Screen Position Within SVG Chart

由 余生长醉 提交于 2019-12-01 07:28:20
问题 I'm using the nvd3.js line with focus chart ( view finder ) model for a project. There are customizations that i need to add to this example -- such as different types of annotation overlays on top of the graph. There's a couple ways i can see tackling this: 1. I could extend the nvd3 chart models to create one that does what i need ( that seems like a lot of work at the moment ) 2. I can find the right interfaces in the existing nvd3 chart models and write my own d3 stuff to create

问题 Does anyone know how I would go making a multi bar graph to be single series? In a working example that i've seen of how i want my graph to look, this function was being used for the data. function dataFactory(seriesNum, perSeries) { return new d3.range(0,seriesNum).map(function(d,i) { return { key: 'Stream ' + i, values: new d3.range(0,perSeries).map( function(f,j) { return { y: 10 + Math.random()*100, x: j } }) }; }); } Below is the code i'm currently using and I will also upload a picture

rCharts - conflict between leaflet and nvd3 in Shiny

由 无人久伴 提交于 2019-12-01 05:26:22
问题 I am trying to include in the same shiny page both a leaflet map and a nvd3 rCharts graph. When I do so, leaflet is no longer displaying the circles / POI I used to display on the map (while not including nvd3). I suspect it is a JS / CSS conflict as when I try to include them separately it works just nice. Once I launch "runapp" and look at the html code, I can see the only difference when including both leaflet and nvd3 are the libraries in use: <link href="nvd3/css/nv.d3.css" rel=
