问题 I have bar chart and I want to draw average line on this bar chart. My solution: In data sets, I add element with type as ' line ': https://stackblitz.com/edit/ng2-charts-bar-template?file=src%2Fapp%2Fapp.component.ts public barChartLabels: Label[] = ['2006', '2007', '2008', '2009', '2010', '2011', '2012']; public barChartType: ChartType = 'bar'; public barChartLegend = true; public barChartPlugins = []; public barChartData: ChartDataSets[] = [ { data: [65, 59, 80, 81, 56, 55, 40], label:

问题 I am using chart.js to show a line chart. How can I hide a tooltip label for a chart.js line chart? The label in the tooltip is showing undefined so I want to hide the label (please see the screenshot)? Perhaps there is a way to modify tooltip where I can show only the legends value in tooltip? My code is as follows: myLine = new Chart(ctx).Line(lineChartData, { type: 'line', responsive: true, scaleShowGridLines : false, bezierCurve : false, animationEasing: "linear", tooltipEvents: [

问题 I'm brand new to d3.js, and I'm struggling to fill in the area between lines in a multivariate percentile graph. I don't want any area filled below the bottom most line, or above the top most line. The first column will always be at the bottom of the graph (5th percentile) The last column will always be at the top of the graph (95th percentile) I need separate area segments between each line I know I need to define an area to fill between (y0, y1) like so: var area = d3.svg.area() .x(function

问题 I would like to create a waterfall plot in R (XYYY) from my data. So far, I use this code: load("myData.RData") ls() dim(data) ##matrix to xyz coords library(reshape2) newData <- melt(data, id="Group.1") dim(newData) head(newData) tail(newData) newDataO <- newData[c(2,1,3)] head(newDataO) ##color scale for z axis myColorRamp <- function(colors, values) { v <- (values - min(values))/diff(range(values)) x <- colorRamp(colors)(v) rgb(x[,1], x[,2], x[,3], maxColorValue = 255) } cols <-

问题 I am new to d3 but I have set the tick interval for my x-axis to every 7 days using d3.timeDay.every(7) . However when my graph is created, I also see a tick mark added for the first of every month. For example, my graph shows ticks at 10/1, 10/8, 10/15, 10/22, 10/29, and 11/1, even though 11/1 is not 7 days after 10/29. If I expand this range to include multiple months, I see a tick at the first of every month. I have included my code for this axis below. What might be causing the first of

问题 This question already has answers here : matplotlib - black & white colormap (with dashes, dots etc) (4 answers) Are there really only 4 Matplotlib Line Styles? (1 answer) Closed 2 years ago . I am new in Python and I want to plot multiple lines in one graph like in the figure below. I have tried write simple plotting code like this: I know these parameters # red dashes, blue squares and green triangles plt.plot(t, t, 'r--', t, t**2, 'bs', t, t**3, 'g^') But I have a lot of lines such in the

问题 I'm experiencing slower than normal response for a LineChart on Raspian - Raspberry Pi. I'm coding an oscilloscope and continuously redrawing 2 series of 500 points (total of 1000 points). Animation is off. Data collection is performant (under 2ms). Current data redraw time is 800 ms or so. Desired redraw time is at least 100ms. I've included code snippets below. What is the best practice for performant javafx chart display on a raspberry pi? Am I taking the wrong approach? Should I be using

问题 I am trying to change the shape of a line chart's points, in my app. I am using afreechart's TimeSeriesChart . I want to make this line fancy in terms of thickness, color and points shape. Where to change the code? which method will use for that? What I'm having now: (source: googlecode.com) What I want: om/svn/doc/screenshot/images/XYDrawableAnnotationDemo01.png) As you can see, in the first chart, the points of the line chart are opaque and rectangle(square?), and in the second one, they
