charts

问题 I have a page which I am trying to show multiple NVD3 charts on tabs. I see on the NVD3 site that they store all chart names ahead of time but I am not sure how I should do this. I have graph models which get stored in the database and then my page must dynamically render all of the charts and appropriate javascript on the fly. So far only the last graph constructed shows :( I render this partial for each graph <%if graph.present?%> <%@graph = graph%> <%end%> <%if @graph.data.empty?%> <%=

问题 We have requirement for line chart as below. We are using highcharts. Our requirement is that chart should display series name at the end of line as displayed in below images. How can we achieve this? 回答1: As an alternative to the renderer() , I find it convenient to use the dataLabels for this purpose. The idea being to disable dataLabels in the plotOptions , but define the position and format anyway. Then enable the dataLabels for the last point in each series' data array. Example:

问题 I am looking for a Julia charting package that allows the user to click on a point in the chart (a bar in a barplot for example). Then send an event that I can interactively receive and interpret which bar was clicked on to then produce another chart of whatever I would like. I have found interactive Julia packages which go the other way. Put a widget on the screen and the user can change a slider for example to change chart. But not clicking on chart. 回答1: PyPlot wraps matplotlib, and

问题 I have a HTML table that serves as the data provider for the chart. The table can be dynamically edited with a click of the button (I can add a new row to it).

Here is my fiddle: https://jsfiddle.net/yvzj8acd/2/ And here is the JS where I add new row to the table: ////////////////////////////////// // This is where I

问题 Look at this picture from my web application ASP.NET 4.0. As you can se the lines have a different length. Also there is duplicate x axis entry. The blue serie has a missing datapoint, the yellow does not. Question 1: How do I align them so the x- axis stays the same. Currently im doing this. And make the lines equally long? Question 2: Is there a way to make the chart interactive so that you can some and hold the cursor on the line to see data from that point, using ASP.NET? int amountofrows

问题 I am stuck with a requirement to display a horizontal line on a ColumnChart to indicate a threshold level. I have the data to the Chart as an ArrayCollection . So my question here : Is it possible to get the location of a value that is shown on the y axis? I think I will be able to place a line or 1px high canvas on top of the Chart to achieve this. Or better, is there any built in functionality that i may have overlooked or is there some open library that can achieve something like this? 回答1
