GWT线图选项 [英] GWT Linechart options
问题描述
我需要在图表中为不同的系列设置不同的线宽。这可以使用系列选项在这里 http://code.google.com/intl/sv-SE/apis/chart/interactive/docs/gallery/linechart.html#Configuration_Options 。但是这个选项在GWT中不可用,这导致了我的问题。
我可以:
- 为GWT编写一个包装器。 http://code.google.com/p/gwt-google-apis / wiki / VisualizationNewWrapper
- 使用Options.set(...)方法。 http://gwt-google-apis.googlecode.com/svn/javadoc/visualization/1.1/com/google/gwt/ajaxloader/ client / Properties.html#set%28java.lang.String,%20com.google.gwt.core.client.JavaScriptObject%29
这两个替代方案的问题在于,当系列选项需要一个对象时,我不知道该怎么做:
series:[{color:'black',visibleInLegend:false},{},{},{color:'red',visibleInLegend:false}]
series:{0:{color:'黑色',visibleInLegend:false},3:{color:'red',visibleInLegend:false}}
如何做到这一点?
方法2更简单:
<您可以使用 Options.set()
并传递另一个 Options
实例。
至少为第二个选项类型。
系列:{0:{color:'black',visibleInLegend:false},3:{color:'red',visibleInLegend:false}}
使用以下代码:
选项options = Options.create();
options.setTitle(title);
选项series_options = Options.create();
series1_options = Options.create();
series1_options.set(color,black);
series_options.set(0,series1_options);
options.set(series,series_options);
I need to set different line width to different series in a chart. This can be done using the series option here http://code.google.com/intl/sv-SE/apis/chart/interactive/docs/gallery/linechart.html#Configuration_Options . However this option is not available in GWT which leads to my question.
I could:
- Write a wrapper for GWT. http://code.google.com/p/gwt-google-apis/wiki/VisualizationNewWrapper
- Use the Options.set(...) method. http://gwt-google-apis.googlecode.com/svn/javadoc/visualization/1.1/com/google/gwt/ajaxloader/client/Properties.html#set%28java.lang.String,%20com.google.gwt.core.client.JavaScriptObject%29
The problem for both those alternatives is that I don't know how to do either when the series option takes an object:
series: [{color: 'black', visibleInLegend: false},{}, {}, {color: 'red', visibleInLegend: false}]
series: {0:{color: 'black', visibleInLegend: false}, 3:{color: 'red', visibleInLegend: false}}
How do I do this?
Method 2 is easier:
You can use Options.set()
and pass another Options
instance.
At least for the second option type.
series: {0:{color: 'black', visibleInLegend: false}, 3:{color: 'red', visibleInLegend: false}}
you can use following code:
Options options = Options.create();
options.setTitle(title);
Options series_options = Options.create();
series1_options = Options.create();
series1_options.set("color","black");
series_options.set("0",series1_options);
options.set("series",series_options);
