amcharts

问题 I'm using amCharts library (it's a JavaScript library for loading data in charts) to extract the data from mySQL database, and display it using a Stock Chart. I found a complete tutorial here: http://www.amcharts.com/tutorials/your-first-stock-chart/ They use static data that they have created in the code, however I want to use my own data by extracting it from database in JSON format.

问题 I'm using AmCharts to make a graph of payments made over time. My configuration of AmCharts looks correct. Also please note I am not a expert in Javascript.

问题 I have an Amchart graph with multiple charts and multiple value axis. Values may be quite different, for example, one chart's values may vary from -3000 to 3000, while another one is 0-40. What I want is to represent all charts so they all will be visible. So, I use 'synchronizeGrid' option. Here's my current code: "synchronizeGrid": true, "valueAxes": [{ "id": "v1", "axisColor": "#FF6600", "axisThickness": 2, "axisAlpha": 1, "position": "left" }, { "id": "v2", "axisColor": "#FCD202",

问题 I have a HTML table that serves as the data provider for the chart. The table can be dynamically edited with a click of the button (I can add a new row to it). I can update the chart each time a new row is added. However the legend remains the same, it only has three initial graphs. How can I update the legend alongside the chart? Here is my fiddle: https://jsfiddle.net/yvzj8acd/2/ And here is the JS where I add new row to the table: ////////////////////////////////// // This is where I

I have followed this example to dynamically update the data in the bar chart http://www.amcharts.com/tips/dynamically-loading-chart-datasets/ I also have a Pie Chart and would like to update the data with the same drop down but I am not sure how to connect it so that it also updates at the same time. Any suggestions ? 回答1: Just expand the function that changes the dataset of the charts

问题 I'm novice on JavaScript, but really amazed by amCharts. So, I ask here, after search a lot on internet: is it possible (or someone can tell me how) make a table as a tooltip on a amCharts graph? I mean: I have a trend graph, based on "date", if I click on a date of a day, view a popup with a table of the details of the day's data. 回答1: Searching and try a lot of code, and I reach a possible solution. So, considering that there aren't similar questions here or developed like I ask, I post my

问题 I need to create a serial chart with AmCharts but I can't get it to plot the nested bySexeDto array's nbre value. Here's my JSON structure. How do I get AmCharts to plot nested structures? 回答1: AmCharts doesn't look at nested JSON structures when drawing the chart. You have to move the nested array in the bySexeDto field into the top level as its own separate element. Here's an example that takes your array and flattens it into a an array of objects resembling {"category": "...", "value0": ..

问题 I am using the amCharts library in my Web application in order to render all the charts. They are working fine, but I need to add a mapChart on the page. I am not as familiar with mapCharts as I am with other charts, as using it seems to require a different approach than the others. Please look at the setup of my code and look at what may have gone wrong within my code.
