These fields with these "machine names" (+ values): The chart below (created using the "charts" module) shows aĬombination chart about all nodes of content type "Article", which has Refer to " Combination chart without aggregation" for an online demo of such chart." field_optionlist" (with some select list values, such as the "year")." field_free_format_text" (assumed to contain some numeric values), with Y-axis left, is used in the parent chart." field_free_format_nr" (assumed to contain some numeric values), with Y-axis right, is used in the child chart.This online demo consists of a combination of 2 " Area charts". $view->human_name = 'Combination chart without using aggregation' $view->name = 'combination_chart_without_using_aggregation' Here is the view (in views export format) that created that chart (using "Line chart" as the format for both charts): $view = new view() If you only change the "settings" for each of the 2 charts to " Line chart" (within "format" of each view), you'd get a similar set of combined charts but shown as line charts instead. $handler->display->display_options = 'perm' $handler->display->display_options = FALSE $handler->display->display_options = 'Combination chart without aggregation' $handler = $view->new_display('default', 'Master', 'default') $view->disabled = FALSE /* Edit this to true to make a default view disabled initially */ Var chart = new CanvasJS.$handler->display->display_options = 'views_query' Follow the steps to creating this without any error.Ĭreate an HTML file named ‘ index.html‘ and put these codes given here. First for HTML, second for CSS, and the third for JavaScript. For creating this program you have to create 3 files. Left all other things you will understand after getting the codes, I can’t explain all in writing. There are prebuilt functions to creating a chart, you have to put data values. As you know this program is based on a library, In the JS file I gave the values, labels, and color to the charts. The layout based on Bootstrap that’s why there is very fewer CSS codes. Now using CSS I gave only a margin and width-height of these two elements. Both divs have a unique ID name to identify and also I have linked other files like CSS, JS, and the Canvas JS CDN link in the HTML file. Then I have created two sections: one for the pie chart and one for the column chart. First I have created the layout using Bootstrap‘s responsive grid system. Pie and Column Chart Using Canvas JS Source Codeīefore sharing source code, let’s talk about it. If you like this, then get the source code of its. Now you can see this visually, also you can see it live by pressing the button given above. See this video preview to getting an idea of how this chart/graph program looks like. If you are thinking now how these two charts actually are, then see the preview given below. You can use this library free in development and educational purpose. But this a demo how we can create charts easily, that’s why the program has a watermark of the library. There I have used a JS library named Canvas JS which is premium you have to buy a license to use it professionally. So, Today I am sharing Pie and Column Chart Using Canvas JS. The pie chart contains slices with different sizes which defines the value of data, also you can see actually value on hover. Both charts have the same values, the pie chart show data in percentage values and the column chart shows in points. Basically, there are two types of charts, one is the pie chart and one verticle bar or column chart. Today you will learn to create a responsive chart using a JS library. We use charts or graphs mostly in the backend site, also sometimes use them in front to show data to users. And the chart is the best way to present or visualize data. Basically, A chart is a graphical representation of data, in which the data is represented by symbols, such as bars, lines, or slices, etc. Previously I have shared Bar Graph program, but this is a pie and column combination chart with a JS library.
