linegraph

问题 I am trying to plot line chart using plotly for multiple dataframes in a single graph. My code is: import plotly.express as px labels=category_names[:10] for category in category_names[:10]: df_b=df1[df1['Country/Region']==category] fig=px.line(df_b, x="Date", y="Confirmed",labels="Country/Region") print(category) fig.show() However, by using the above code I am just able to get the line graph for last iteration of for loop. Current output: Desired Output: Kindly help me with the code! 回答1:

问题 I apologize that I am a beginner in R. I am trying to make the graph like the below picture. This is what I did in code. But it does not work : unemp <- read.csv("unemployment.csv", stringsAsFactors = FALSE) # adding background colors for different presidents name <- c("Truman", "Eisenhower", "Kennedy", "Johnson", "Nixon", "Ford", "Carter", "Reagan", "Bush I", "Clinton", "Bush II", "Obama") start <- as.Date(c("1948-01-01", "1953-01-20", "1961-01-20", "1963-11-22", "1969-01-20", "1974-08-09",

问题 I'm trying to generate a graph with gradient/shading effect. Now I'm able to draw line graph and applied gradient effect to that graph. It is applying to whole view not to the graph. Now I'm getting image like this. But I want like this. I want gradient effect just under the graph. Please help me in this. Thanks in advance. The code that I'm using is: UIGraphicsBeginImageContext(self.graphView.frame.size); [graphView.image drawInRect:CGRectMake(0, 0, self.graphView.frame.size.width, self

问题 I'm new to Bokeh and I'm trying to create an interactive plot of weather data. There are two Select menus, one for sensor ID (132, 133, ...), and one for variable (Temperature, Dew Point, ...). When the user changes either value, the graph is supposed to update with the selected data. The data I'm using is in a Panda Dataframe, where there is a column 'dt' which contains the one minute interval datetime objects, and the data are in columns that follow the naming convention 'Temp132', 'Temp

问题 Hello People, I am trying to use the geom_line function to create line graphs in R. I want to assign specific colours to each line and I am unable to do so. When I try to manually assign the colours I get the colour names as variables and in the legend they get arranged alphabetically. If I don't then I don't get any colours at all. I also looked around on the web and noticed that there should be a grouping variable by which colours can be assigned. Unfortunately, in my dataset here, each

问题 How would I set the x_axis labels at the indices 1,2,3....n to be something different. lam_beta = [(lam1,beta1),(lam1,beta2),(lam1,beta3),....(lam_n,beta_n)] chunks = [chunk1,chunk2,...chunk_n] ht_values_per_chunk = {chunk1:[val1,val2,...],chunk2:[val1,val2,val3,.....]...} color='rgbycmk' j=0 for chunk in chunks: plt.plot([hr_values_per_chunk[chunk][i] for i,item in enumerate(lam_beta)],[i for i,item in enumerate(lam_beta)],color=j%len(color)) j+=1 plt.set_xticks([i for i,item in enumerate

问题 I'm trying to draw ROC curves using an existing set of values using the following command plot(X1,Y1,'--rs',X2,Y2,'-*g'); Where X1 , Y1 , X2 and Y2 are matrices that have the same size However, the lines produced by this command are straight ones. How can I make them curved lines. Thanks Aziz 回答1: MATLAB by default uses straight line approximation to draw your graph in between control points. If you want, you can interpolate in between the points to produce a more realistic graph. Try using
