I have a customer who needs to convert a diagramming application (which was developed in MFC a long time ago) to C#. The application displays large networks (lots of graphical elements), and lets the user edit/manipulate the data through a graphical ui. I decided that it would be best to use a library rather

问题 I'd like to use ggplot2's stat_binhex() to simultaneously plot two independent variables on the same chart, each with its own color gradient using scale_colour_gradientn(). If we disregard the fact that the x-axis units do not match, a reproducible example would be to plot the following in the same image while maintaining separate fill gradients. d <- ggplot(diamonds, aes(x=carat,y=price))+ stat_binhex(colour="white",na.rm=TRUE)+ scale_fill_gradientn(colours=c("white","blue"),name =

I'm interested in drawing a treemap: What is the easiest way to make one in Python? Is there a library that could produce such a graphic, given the proper input data? 回答1: The SciPy cookbook includes an example using matplotlib, but without labels.

问题 I have a very simple Shiny app, wherein I have a set of data on past customers, and a set of data on 3 new customers. All my data consists only of 2 variables: age and score. The purpose is to select one of the 3 new customers, and see how the past customers of similar ages scored. We do this with a simple scatterplot. For example, since new customer #1 is 30 years old, we get to see how all the past customers of ages 25 - 35 scored: (my apologies for the small image) Everything works fine.

问题 I'm working with matplotlib to plot a variable in latitude longitude coordinates. The problem is that this image cannot include axes or borders. I have been able to remove axis, but the white padding around my image has to be completely removed (see example images from code below here: http://imgur.com/a/W0vy9) . I have tried several methods from Google searches, including these StackOverflow methodologies: Remove padding from matplotlib plotting How to remove padding/border in a matplotlib

问题 I have a problem with an MS Chart chart type column. If there are more than 9 bars in the chart, the axis-x labels won't show up properly, some of them just disappear. Here's my mark-up for the chart: <asp:Chart ID="chtNBAChampionships" runat="server"> <Series> <asp:Series Name="Championships" YValueType="Int32" Palette="Berry" ChartType="Column" ChartArea="MainChartArea" IsValueShownAsLabel="true"> <Points> <asp:DataPoint AxisLabel="Celtics" YValues="17" /> <asp:DataPoint AxisLabel="Lakers"

However, it does not let me visualize tree option at all. Could anyone please guide me how to get the tree diagram in weka by using data sets available online? 回答1: Look here http://maya.cs.depaul.edu/classes/ect584/weka/classify.html, for example. First you have to fit your decision tree (I used the J48

问题 I am using networkX to draw a network plot from a distance matrix(emoji_sim, a DataFrame). Here is the code: G = nx.from_numpy_matrix(np.array(emoji_sim)) nx.draw(G, edge_color='silver', node_color='lightsalmon', with_labels=True) plt.show() I know there is a way to relabel the nodes as: G = nx.relabel_nodes(G, dict(zip(range(len(G.nodes())), range(1, len(G.nodes())+1)))) But I want to substitute the nodes label with images(possibly read from files or using Python Emoji package). Is there any
