问题 I want to display a graph very similar to below tradingView chart in amCharts. The problem is how can I fill the area between two specific line graphs with different fill color depending on which line graph is above the other. Using fillToGraph will always fill the same color regardless of whether that graph is below or above the another graph and ends up mixing both the colors as shown below. I am using amCharts v3. Please help. 来源： https://stackoverflow.com/questions/53446791/conditional

问题 I'm using AmCharts to display two datasets which represent number of downloads per two file types: pdf and xls. The chart is similar to the one available at https://www.amcharts.com/demos/multiple-data-sets/, but I set recalculateToPercents option to 'never' to always display actual downloads count for compared series. I'm using hourly period. The problem I encounter is that in situations when there are no downloads in specific hour for first file type (the main dataSet), the value for second

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.

Angular 2 and AmCharts

Does anybody have any idea on how to implement Amcharts into Angular2 (BETA)? I was trying to follow the path/pattern of this question however, I was pretty successful with charts.js, but unfortunately, I can't use charts.js,for my charting program. Since it seems like everything in Angular2 Beta is uncharted territory, I don't have a clue where to start? I mimicked the charts.js example above with no luck, no error. /// <reference path="../DefinitelyTyped/amcharts/AmCharts.d.ts" /> There is a DefinitelyTyped library for amcharts (not one for plot.ly yet). UPDATE: Here is the directive: ///
