label

问题 I want to know if it is possible to end a for loop in C++ when an ending condition (different from the reacheing right number of iterations) is verified. For instance: for (int i = 0; i < maxi; ++i) for (int j = 0; j < maxj; ++j) // But if i == 4 < maxi AND j == 3 < maxj, // then jump out of the two nested loops. I know that this is possible in Perl with the next LABEL or last LABEL calls and labeled blocks, is it possible to do it in C++ or I should use a while loop? Thank you. 回答1: You can

问题 I have a plot created in ggplot2 that uses scale_fill_gradientn . I'd like to add text at the minimum and maximum of the scale legend. For example, at the legend minimum display "Minimum" and at the legend maximum display "Maximum". There are posts using discrete fills and adding labels with numbers instead of text (e.g. here), but I am unsure how to use the labels feature with scale_fill_gradientn to only insert text at the min and max. At the present I am apt to getting errors: Error in

问题 Im making a list of addresses that the user will select from, and the address text will be returned. I need to use Tkinter.Label because the Tkinter.Listbox will not allow for newlines.

问题 I have created a force directed graph but I'm unable to add text to the links created. How can I do so? Following is my code link I have used the following line to append the titles on the link's, but its not coming. link.append("title") .text(function (d) { return d.value; }); What am I doing wrong with this ? 回答1: This link contains the solution that you need. The key point here is that "title" adds tooltip. For label, you must provide slightly more complex (but not overly complicated) code

Here's the relevant code: plt.bar(i, bar_height, align='center', label=country ,color=cm.jet(1.*counter/float( len(play_list)))) xticks_pos = scipy.arange( len( country_list)) +1 plt.xticks(xticks_pos ,country_list, rotation=45 ) Does anyone know a solution?

问题 Is there an easy way to align text labels between ticks? Here is my time axis with labels above the ticks: I would like to place these labels like here: 回答1: I ended up with one of the Lars Kotthoff's advices. Every time when I call(axis) I also adjust text labels. Here is simplified code: function renderAxis() { axisContainer .transition().duration(300) .call(axis) // draw the standart d3 axis .call(adjustTextLabels); // adjusts text labels on the axis } function adjustTextLabels(selection)
