问题 The legend for d2 looks fine; for d1 , I would like to show just the hoizontal line against a white/transparent backgounnd. df = data.frame( Date = c("2012-11-30", "2012-12-03", "2012-12-04"), d1 = c(9, 5, 11), d2 = c(4, 6, 3) ) ggplot(df, aes(Date)) + geom_bar(aes(y = d2, color = "d2"), stat="identity", fill = "red") + geom_line(aes(y = d1, group = 1, color = "d1")) + scale_colour_manual("", values=c("d1" = "blue", "d2" = "red")) 回答1: It is not an elegant solution but at least it gives some

问题 My task is to draw a graph in chart control using mouse and retrieve the (X,Y) points from the Graph. I tried of drawing a graph with mouse. Here is the normal Graph looks like. After drawing with mouse, it looks like : The code which i used to draw graph is : private void Form1_Load(object sender, EventArgs e) { chart1.ChartAreas[0].AxisX.Minimum =0170101; chart1.ChartAreas[0].AxisX.Maximum =0175951; chart1.ChartAreas[0].AxisY.Minimum=0780101; chart1.ChartAreas[0].AxisY.Maximum=0785951;

问题 Using a big space performing long numbers is not a good decision. If I have a graph with a medium scale about 50 000, on the Y axis will be written "50 000, 60 000, 10 000". Can I perform it there like 50 * 10^3 or something else? It's necessary for charts with several scales like here 回答1: Use a tickLabelFormatter on the axis. For example: NumberFormat format = new DecimalFormat("#.#E0"); yAxis.setTickLabelFormatter(new StringConverter<Number>() { @Override public String toString(Number

问题 I am in need to add a zero point for category axis in javafx line chart. In the image I want some "T0" to represent the zero mark of origin on the x axis, so that I can mark point on y axis as on the chart. sample line chart ( looks like bar chart !) 回答1: I'm not completely clear what you're asking, but if you want the pixel coordinates of the left end of the x-axis, you can do Category xAxis = ... ; // ... double leftEnd = xAxis.getDisplayPosition(value0) - xAxis.getCategorySpacing(); where

问题 So I have a page written using Django where someone can enter information into a form, and on submit it accesses a SQLite database to retrieve the queried information. So far I have gotten this far, but I am not able to create and show a plot below the form on the page. I have tried different packages: ChartIt , Graphos and nvd3 .

问题 LineChart has series which have different color by default. How can I get it to set obtained color to other text connected with the specified series? 回答1: In a line chart since all elements of a single series have one color. The series are assigned with styleclass series0 , series1 , series2 etc. Each of these series are assigned with corresponding colors styleclass i.e. default-color0 , default-color1 , default-color2 etc. You can directly use the styleclass for your text/labels. 来源： https:/
