问题 Currently I'm using matplotlib to plot a 3d scatter and while it gets the job done, I can't seem to find a way to rotate it to see my data better.

问题 How can i draw a following plot in R? Red = 30 Yellow = 40 Green = 30 Needle at 52. Pls help me out as i am in great need. Thanks 回答1: So here's a fully ggplot solution. Note: Edited from the original post to add numeric indicator and labels at the gauge breaks which seems to be what OP is asking for in their comment. If indicator is not needed, remove the annotate(...) line. If labels are not needed, remove geom_text(...) line. gg.gauge <- function(pos,breaks=c(0,30,70,100)) { require

问题 I want to be able to add multiple points as a reference place where I can show the horizontal line. Here is an image of what I'm trying to achieve: I want to also make it so that when you don't hover over a point its opacity gets reduced and when you hover over it the opacity is normal.

问题 I have an issue with displaying a Google Chart in a Boostrap tab. I have two tabs, and a Google Chart in each. In the first one, the chart is correctly displayed, but in the second one, the chart is tiny and compressed. I don't understand why.. Here is my code : <div class="tab-pane active" id="player"> <h3>Players' resources</h3> <div id="totalPlayerChart" style="height: 500px;"></div> </div> <div class="tab-pane" id="producer"> <h3>Producers' resources</h3> <div id="totalProducerChart"

问题 How can I obtain the corresponding x-axis value (xIndex) of a pixel point in a ScatterChart? I have been looking through the source code of the library and I think that one of the methods below (which I copy/pasted from the source code from the library here) can help. It seems getValuesByTouchPoint is the correct method but I don't know how to use it. /** * Transformer class that contains all matrices and is responsible for * transforming values into pixels on the screen and backwards. * *

问题 I have a list created from a linq query that contains 2 columns of data. var result = root.Descendants().Elements("sensor") .Where(el => (string)el.Attribute("name") == "Sensor1") .Elements("evt") .Select(el => new { t1 = el.Attribute("time").Value, v1 = el.Attribute("val").Value }) .ToList() I'm trying to use the chart control datasource to use that list, but when I call the bind method I receive this error: System.ArgumentException was unhandled HResult=-2147024809 Message=Series data

问题 I am trying to set up my program so that the user can display a stacked column chart that displays the number of reject categories that appear in each department (for example, 5 appear in department 1, 3 in department 2, etc). I've had a look around online and taken a crack at it myself but I cannot seem to get it working. If anyone would be able to help that would be fantastic. What the chart currently does when the user presses a button to switch to a stacked column chart: Code: private

问题 I created a column chart in my application which look like this: As you can see the positive values are green and the negative values are red. I need to represent this in the legend. I just don't know how. What I already tried: I added CustomItems to the Legend .
