问题 Values for my Chart range from 10 to 70000. Since 70000 is too large, small values are not visible in the chart and I cannot view its label on hovering over it.

Rails simple_form label_html

由 a 夏天 提交于 2019-12-24 01:13:18
问题 I'd like to override the margin between the input & its label on one form -- can this be done via :label_html => .... ? The example on github shows a :class => 'special' being passed. Do I need to set up something in my .css file? if so, how would I do that (meaning, do I label it with a ., or a #, or nothing)? The css I've got has a "simple_form label" with some settings, I'm guessing I need to do something similar, but I'm just having difficulty putting the pieces together.. Thanks 回答1: Yes

Change Style of Selected Radio Button Label

由 不想你离开。 提交于 2019-12-23 19:26:12
问题 I'm attempting to change the border color of a radio button label when it is selected in the form. I found this question which is pretty much exactly what I am looking to do: CSS - How to Style a Selected Radio Buttons Label? but when I try it with my own code the color doesn't change on select. This is driving me nuts, I can't figure out why it won't apply the border color - any help is very much appreciated. I have uploaded the code I am working with here: http://jsfiddle.net/SHfr5/ but I

Gnuplot, how to include a space character in key titles?

由 大兔子大兔子 提交于 2019-12-23 18:07:19
问题 I want to use key titles like "Best F" "Worst F" for a gnuplot 4.4 graph, when reading the data from a file, but I can't figure out how to put the space, e.g.: Generation Best_F Worst_F Average_F 5 4 9 5 4 3 9 4 I tried writing in the file "Best F", "Best%20F" "Best\ F" but they get split, when read as column headers, or I get the ugly looking "%20". plot for[col=2:4] data.dat using 1:col title columnheader(col) Or is there a way to do a character substitution, like "Best_F"%" "->"Best F"?

Xamarin.Forms: the MultiLineLabel doesn't longer work on Android
