Chart with scroller

官网事例:http://www.amcharts.com/line/chart-with-scroller/

amcharts可以用来做成漂亮的flash报表,jfreecharts能做的图基本上它都可以做出来.

下面主要是对amline_settings.xml这个文件的一些属性进行说明:

<?xml version="1.0" encoding="UTF-8"?>
<!-- Value between [] brackets, for example [#FFFFFF] shows default value which is used if this parameter is not set -->
<!-- This means, that if you are happy with this value, you can delete this line at all and reduce file size -->
<!-- value or explanation between () brackets shows the range or type of values you should use for this parameter -->
<!-- the top left corner has coordinates x = 0, y = 0     -->
<!-- "!" before x or y position (for example: <x>!20</x>) means that the coordinate will be calculated from the right side or the bottom -->

<!-- 值在[]中, 例如 [#FFFFFF] 如果[]中没有设置参数，则为默认值 -->
<!-- 如果你乐意，你可以删除注释来减少文件尺寸 -->
<!-- ()的值用来描述范围或类型，例如(0-100) or (Integer,String)    -->
<!-- 左上角坐标是 x = 0, y = 0  -->

<settings>

  <skip_rows></skip_rows>跳过前多少行,默认0

  <decimals_separator>,</decimals_separator>小数点分割符

  <digits_after_decimal>2</digits_after_decimal>精确度

  <reload_data_interval></reload_data_interval>动态加载数据间隔时间

  <start_on_axis></start_on_axis>起始从原点开始

<hide_bullets_count>20</hide_bullets_count>                大于20就不显示曲线标志

<!-- [] (Number) if there are more then hideBulletsCount points on the screen, bullets can be hidden, to avoid mess. Leave empty, or 0 to show bullets all the time. This rule doesn't influence if custom bullet is defined near y value, in data file -->
