问题 I need to add circules/nodes to each point on a line chart of nvd3. I have my codes here - https://jsfiddle.net/sujit77/7ns2g4a1/12/ Also I need to have these circles with different colors depending on value at that point. I tried to follow "http://www.d3noob.org/2013/01/change-line-chart-into-scatter-plot.html".

问题 I am trying to customize candlecharts from google charts.

问题 I am unable to add a line on a second axis (right axis) on an existing chart. Is there a way to do this with the new implementation of Charts in POI 4.0.0/1? Desired output will look like this (A simple excel chart with 2 axes): . The associated data to that chart as an example: Series 1/Axis1 = [1, 2, 3, 4, 5, 6, 7, 8, 9] Series 2/Axis2 = [200,300,400,500,600,700,800,900,1000] Here is the code that I am trying so far in Java, it is mostly replicated from the LineChart.java example //Initial

问题 I ran into a wall setting minimum- and maximumscale properties of a chart's secondary axis - kept getting an "object does not have this property" error. I fixed it, but I'd like to know how. After too many hours of googling and trying different options (Three.

问题 I need to implement a line chart inside my application and I would like to make use of MPAndroidChart. The problem is that the value on the y axis will be somewhere between 1 and 1x10^-12.

Thanks for your help. 回答1: This chart library uses Matrix -multiplication for value to pixel transformation. Those are linear-transformations, which means they cannot stretch

问题 Answer: TL;DR: pasting a chart with embedded data takes a long time so you have to install a delay to prevent vba from moving on before the paste operation completes. Question:I'm trying to paste an excel chart with embedded data into a powerpoint presentation. The only thing I am getting hung up on is referring to and positioning the chart in ppt once it has been pasted. Dim newPowerPoint As PowerPoint.Application ActiveSheet.ChartObjects("Chart 1").Activate ActiveChart.ChartArea.Copy

问题 I need to create a stacked bar chart showing the engine status in a day. Here is the example of what I would like to have: It looks like a gantt chart, but probably much simpler than a normal gantt chart. I am badly looking for a JavaScript/jQuery charting library which supports this kind of chart. I know lots of gantt chart library available, but wondering which library have the option/setting for the chart I want. My data would be in this format: [ { "day": "2009-07-13", "work": ["11:16:35

问题 I just want to display the Y values right above the chart line, I found that the method to do this is setting setDisplayChartValues to true. However when I use it the app crashes with the following error message: java.lang.IndexOutOfBoundsException: Invalid index 3, size is 3 being 3 the number of points in the chart. public class LineGraph { private XYMultipleSeriesRenderer mRenderer = new XYMultipleSeriesRenderer(); private double max = 0; private double min = 999; public View getView
