bar-chart

问题 I have this dataframe and want to plot it as a grouped bar chart. I checked this question (Grouped Bar graph Pandas), It has a group with its value, not columns. How can I have a grouped bar chart with column? num_thread num_iter time category ORIGINAL 1 100000000 1360.0577 ORIGINAL 1 200000000 2731.8207 ORIGINAL 1 400000000 5440.8003 OMP 2 100000000 692.5336 OMP 2 200000000 1398.5305 OMP 2 400000000 2765.7757 OMP 4 100000000 362.1932 OMP 4 200000000 724.6331 OMP 4 400000000 1447.0628 OMP 8

问题 I'm creating a BarChart that contains multiple frequency bands as the category axis. What I want to do is to show a visible grouping of these frequency bands: For example: Freq x1 ~ Freq x2 = Band y (so the domain axis has values for category x1, x1.1, x1.2 till x2) Freq x3 ~ Freq x4 = Band z (x3, x3.1 .....x4) What I want to do is show markers for Band Y and Band Z in the graph. Note that based on the dataset that I may get, not all categories may be present. Say, for the 1st example, I've

问题 I am displaying a bar chart and trying to have the labels above bars displayed in correct locale (they are floats). I am developing in JasperSoft Studio 6.2.0. I set the global and/or the report (execution-time) locale to en_US , but the labels are still displayed in my Windows locale ( nl_NL ). I then set the label expression to new DecimalFormat("#,##0.0##;(#,##0.0##-)").format($F{Hours}) but it's still in Windows locale. Only when I explicitly set the label expression to en_US locale:

问题 The following code creates a Barplot in R. However, the 1st column is empty. I don't understand why... There is no NA values in my data set. How can I remove the space between the "Bayview Column" and the Y-Axis? # 2. Bar Plot for Police District barplot(xtabs(~sample$PoliceDistrict), main="Police District Distribution of Incidents", xlab="Number of Incidents in Police District", ylab="Frequency", col=rainbow(nlevels(as.factor(sample$PoliceDistrict))), las=2, # cex.lab=0.50 This is for the x

问题 Hi I am new to android and I am writing the following code to draw a bar graph taking the values from the database. I have created the database using sqlite data browser. My problem is that when I execute the program the graph doesnot plot. Thanks for your help in advance. public class ChartActivity extends Activity { private String productName; private Context Jayant; private Integer seriesCount; public Intent execute(Context context) throws IOException { SharedPreferences myPrefs = context

问题 I'm trying to create a figure similar to the one below (taken from Ro, Russell, & Lavie, 2001). In their graph, they are plotting bars for the errors (i.e., accuracy) within the reaction time bars. Basically, what I am looking for is a way to plot bars within bars. I know there are several challenges with creating a graph like this. First, Hadley points out that it is not possible to create a graph with two scales in ggplot2 because those graphs are fundamentally flawed (see Plot with 2 y

问题 I'm using a bar chart and I need that the bars to be gradient rather than solid colors.In the code, you can see that I add "role: style" and after a solid color, but I need that the to have a linear gradient. function drawChart2() { var data = google.visualization.arrayToDataTable([ ["Element", "Difference", { role: "style" }], ['Mg', 1.2 , "#1aab54"] ]); var view = new google.visualization.DataView(data); view.setColumns([0, 1, { calc: "stringify", sourceColumn: 1, type: "string", role:

问题 Hi I'm trying to accomplish a time stacked bar chart where the input data looks like this: {"name":"Folienwechsel", "starttime":"02/29/2012 09:50:07", "endtime":"02/29/2012 09:50:46", "duration":38546.0}, {"name":"Pause", "starttime":"02/29/2012 09:50:46", "endtime":"02/29/2012 09:51:36", "duration":49943.0}, {"name":"Wartezeiten", "starttime":"02/29/2012 09:51:36", "endtime":"02/29/2012 10:04:43", "duration":787086.0} As you see the start time and end time are continued, when a state finish
