amcharts

问题 I have these two ValueAxes : { ... minimum: 0, maximum: 100, strictMinMax: true, autoGridCount: false, gridCount: 10 }, { ... minimum: -15, maximum: 215, strictMinMax: true, autoGridCount: false, gridCount: 10 } Now the grid lines of both axes are creating a total mess in the chart and its hard to not get confused while trying to read values. The reason for this is, that AmCharts rounds the labels up or down to ten-steps, not respecting the gridCount . I need to know if there's a way to get

问题 I am having a lot of difficulties navigating through amCharts Docs and I cant seem to find the answer to this online.

问题 I would like to change the language of a ammap (V4). Therefore I followed the example which is provided here (but it is for V3): http://jsfiddle.net/tDqs2/25/ Here first the language get loaded via a script tag. <script src="http://cdn.amcharts.com/lib/3/lang-maps/de.js"> Now if I follow the instructions I don't see any map. Here is my codepen: https://codepen.io/ms92o/pen/mjMpZy that line does not work: chart.language = 'de'; Looking at the API for language I do find a language property:

问题 Let consider my question on a sample from amCharts site: https://www.amcharts.com/demos/area-with-time-based-data/ So, after page loading, chart is zoomed between 03:30 and 6:00 (based on X-axis values) and vertical grid step (difference between two vertical grid lines) is 0:30. Now, I grab left slider at the top and move it right, so that minimal X value is 04:00. And there's still 0:30 step. It will switch to 0:10 at ~04:05. My question is - how can I manually "speed up" this process of

问题 I am using stock charts in Amcharts and plotting the graph as below: Working Pen Now Instead of giving the data in the script I wanted to load from a URL.So I instead of "dataSets": [{ "dataProvider": sourceData, "categoryField": "time" }] I replaced it with "dataSets": [{ "dataLoader": { "url": "http://localhost:8080/contacts?day=3&zone_id=3" }, "categoryField": "time" }] But it did not work.

问题 Closed . This question needs details or clarity. It is not currently accepting answers. Want to improve this question? Add details and clarify the problem by editing this post. Closed 4 years ago . I'm growing desperate with amCharts doing the simplest task. Well, at least what I think is simple. I want to create a normal line chart with "normal" data. What do I mean with normal? Well, having an array with my y values, and maybe also one for x: x = [1,2,3,4] y = [5,6,7,8] Shouldn't it be
