Rails, Chartkick: Show values on the charts

由 霸气de小男生 提交于 2019-12-10 18:28:27
问题 The Chartkick gem lets you create many kinds of charts. Currently, my charts look like this: pie_chart @institutions column_chart @stats I want that values are shown on the charts. In the pie chart, I want the number 244 and 43 be visible in or outside of the pie chart. In the column chart, I'd like to have the values on top or in the column. Is this somehow possible? Regarding to the pie chart, there is already a stackoverflow-question, but the accepted answer does nothing for me: pie_chart

问题 I'm using chartckick in my RoR project to generate charts, which works quite nice. (along with Google Charts). I've created a column chart with only 2 bars (male and female). And now the client wants that each bar have different color? Is that possible? I've seen this post - How to change the color of a Column-chart created with Chartkick? but it's more then half of year old and I'm hoping that there is a way now to specify more colors to the bars. Update My code looks like: Controller

Sinatra and Chartkick Example

由 ◇◆丶佛笑我妖孽 提交于 2019-12-05 18:19:37
I am quite new to Ruby as web platform and learn best by adapting and expanding examples. I like Sinatra and want to use it and Chartkick to display charts. Unfortunately, I'm having trouble getting even the most trivial example running and there seems to be a dearth of full examples (lots of 'one liners'). Here's what I have: require 'sinatra' require 'chartkick' get '/' do '<%= javascript_include_tag "//www.google.com/jsapi", "chartkick" %> <%= pie_chart({"Football" => 10, "Basketball" => 5}) %>' end So what devastatingly simple thing am I doing wrong? Any help would be greatly appreciated.

Rails chartkick: want only integer values on axes. Use discrete or something else?

由 久未见 提交于 2019-12-04 11:54:09
问题 Say I have the following code <% data = [ [1,1],[2,3],[3,5],[4,8],[6,4],[7,2] ] %> <%= line_chart data, {discrete: true, library: {width: 600} }%> Using chartkick, this produces the following graph I want the vertical axis to be labeled using integers. (not decimals) I thought that the discrete option was supposed to do this but for this example all it did was change the format of the elements on the horizontal axis from time to number (i.e. the following code <%= line_chart data, {library:

Rails 5.1, chartkick a sum with multiple currencies

问题 I'm stuck on a tiny problem regarding chartkick. I have a rail app where you can create different currencies. You can then create a expense with a title, a amount and choose the currency from a list and the user_id. The relations are made and working. I have in my user controller something like this : @user_spendings = @current_user.spendings.all.order('date DESC').paginate(:page => params[:page], :per_page => 15) @sums_by_currency = Currency.joins(:spendings). select(:symb, 'SUM(spendings
