问题 Hi I am trying to adapt Matthew Izanuk's Unit Bar Chart with Brush and Zoom to a randomly generated bar chart I have already created.

R Shiny dataTableOutput not displaying Brushed Points

◇◆丶佛笑我妖孽 提交于 2019-12-08 09:48:21
问题 I'm developing an R Shiny dashboard using the Iris data in the ggplot2 dataset. It has three main components, a sidebar panel to select the variables to display in the plot, a ggplot with brushed points and a datatable below which shows the data of the brushed points. Everything works perfectly except the datatable does not seem to select the data points on the table. From what I can tell it has something to do with the line output$plot_brushed_points in the server. Any help would be greatly

How to clip Image (UI-element) to sample geometry?

问题 I want clip Image to ellipse, for example. UI-element have Clip, but Clip in the Windows Runtime API must be a RectangleGeometry. I can achieve the same result using an Ellipse and ImageBrush element as Fill brush: How to clip image to ellipse in XAML But then i can not size or move my image, because it's brush, not UI-element. So, how clip image not rectanglegeometry? For example, i want this:Move image into ellipse Maybe, i can use alphamask to UI-element? Or OpacityMask? Maybe this is

D3 Brush coordinates under CSS transform scale

无人久伴 提交于 2019-12-08 07:00:50
问题 D3 brush does not function properly under css transform scale. When svg is under div element, and div element is transformed using CSS scale, the brush operation shows wrong coordinates. To demonstrate this case, here is the jsFiddle. It is simple modification from Bostock's Brushable Network example. What I did was simply putting SVG in the div element and made div element zoom 50% using CSS transform scale(0.5). And the brushing coordinates are not updating because of zooming. #test {

Shiny click/brush not working with non-cartesian coordinates?

陌路散爱 提交于 2019-12-07 20:54:15
问题 I am working on a Shiny app that should let a user select geographical data points on a world map generated by ggplot2 (as in this example). This works if I use the regular coord_cartesian coordinate system (which distorts the maps) but fails if I use the more appropriate coord_map coordinate system. It seems like the click/brush events do not receive the correct coordinates after the projection. Is there any way I can work around or fix this without reverting back to cartesian coordinates?

d3.js: limit size of brush

家住魔仙堡 提交于 2019-12-07 03:35:57
问题 Is there a way to limit the size of a brush, even though the extent is larger? I put together a brush with only an x-scale that can be moved and resized. I would like to be able to limit the extent to which it can be resized by the user (basically only up to a certain point). In the following example, the brush function stops updating when the brush gets bigger than half the maximum extent. The brush itself, though, can still be extended. Is there a way to prevent this from happening? Or is

Zooming and brushing in d3 force directed graph

梦想的初衷 提交于 2019-12-07 01:50:25
问题 I'm having a problem in getting D3 to perform proper brushing when zooming is performed. I have a jsFiddle created here http://jsfiddle.net/Gwp25/2/ showing the network with some dummy data I found elsewhere. The operation to follow is this. Zoom in (using mousewheel), then turn on brushing. After doing this, brush the nodes. The nodes that are selected are off - some out of the brush area. Here is the relevant part of the code dealing with the selecting of nodes within the brush extent. .on(
